Glowlight tetras or Hemigrammus erythrozonus are native to the Essiquibo basin in South America. Glowlights like all tetra are a member of the family Characidae. They received the name glowlight tetra because of the highly reflective red stripe that runs from their mid-body to their tails. This stripe appears to glow under aquarium lighting.

Tetras are shoaling fish. Shoaling fish are extremely social fish that instinctively travel in a group. They tend not to fare well in an aquarium devoid of other members of their species. Depending on how strong the instinct runs in an individual species, some shoaling fish cannot survive at all in an isolated environment. It is always advisable to have at least four of any given shoaling fish in a community fish tank.

The glowlight tetra is a small freshwater fish variety, reaching an adult length of only about an inch and a half. They have a mild disposition and make wonderful additions to community tanks provide they are in the presence of similarly natured fish whose size is not big enough to view them as a source of nutrition.

Glowlights, like all tetras, are hiders. They take readily to heavily planted aquariums. Giving them plenty of places to hide will increase these rather small fishes' chances of long-term survival in a community setting. Glowlights are mid-tanks swimmers. So you want vegetation large enough to be present in the middle of your aquarium.

Most freshwater species native to South America thrive in slightly acidic water. Glowlights are no exception. Glowlights are accustomed to a pH level of around 6.8 with a water temperature between 75-83 °F.

Tetras are omnivores by nature. They can survive perfectly well on a diet of garden-variety tropical fish food flakes. They will also eat frozen and freeze-dried products and live food such as brine shrimp.

Male and female glowlights have an identical color palette. You can generally distinguish between sexes by the shape of their bodies. Female have a fuller, more rounded body than males. This trait is more pronounced when they are carrying eggs.

Glowlight tetras are more apt to breed in an environment that closely mimics their native waters. Filtering the aquarium water through peat or adding a thin layer to the substrate will help make them feel at home. Make sure the peat doesn't contain chemical additives or fertilizers. A breeding tank should always be used. Provide the tank with plenty of fine-leafed foliage. Hornwort will work well for this purpose.

The glowlight tetra is an egg layer. Egg layers are notorious for eating their un-hatched eggs. Tetras will scatter their eggs among the plants instinctively. Promptly remove the adults from the breeding tank after spawning.

Fry will hatch in about 24 hours. Newly hatched fry can feed a liquid fry food formulated for egg laying fish. In a few days, their diet can be switched over to newly hatched brine shrimp. Powdered eggs are an acceptable substitute. In a week or so they can be fed finely crushed tropical fish flakes.

    Freshwater fish are the most popular aquarium fish worldwide because of their inexpensive price and ease of care. Many aquarium owners don't realize that there is a rather exotic alternative to freshwater fish in the realms of affordability and upkeep. Jellyfish aquariums are the hottest new trend in the aquarium industry. Jellyfish do require a special Jellyfish Aquarium Fish Tank in order to survive but they are far easier to keep alive and healthy than saltwater fish. Pet Moon Jellyfish look absolutely incredible under a fading LED lighting system.

Originating from South America, Cardinal tetra fish are very common among the fish-keepers and are found in many aquariums and tanks all over the world. They are freshwater fish and easy for the beginners.

Their body is decorated with a blue line dividing the body. The body carries red stripes which are longer. Actually, that is the distinguishing feature between a cardinal tetra and neon tetra fish. If the stripes are short, the fish is neon tetra.

In fact, the name cardinal tetra comes from this red color. It resembles the red robes which are worn by the Cardinals!

Cardinal tetras are difficult to breed in captivity so their availability is always lesser than the demand. Many pet fish stores sell cardinal tetras which are caught from their natural habitat. They are not endangered species and they are found in plenty.

They have a very short life-span of about a year, so their entire life cycle including reproduction finishes during this period. However, if you provide the ideal conditions for them in your aquarium, they can live a much longer life.

They will grow only up to 2 inches in length so they don't require a large aquarium. You can accommodate them even in a small tank of 5 gallons. As they are peaceful by nature, you can keep them in community aquariums also. Most of the time, they stay in the middle of the water so you can keep other bottom-dwelling or surface swimming fish with them.

There is no problem while feeding cardinal tetras. They can accept all types of food including vegetables, flaked food and live food like brine shrimp or blood-worms.

If you can provide the environment which resembles in South American rivers where they are found, they will live happily for a long time. The pH level of the water should be lower and the temperature of the water should be around 72-82 degrees F. They can survive even in the higher temperatures. The hardness of the water should be moderate.

Only important factor while keeping cardinal tetras is the level of toxic elements in the water. They are sensitive about the nitrates and nitrites in the water and you should set up a good filtration system to keep the water clean. In addition, you should make frequent replacements of the aquarium water.

You should provide a thickly planted aquarium for the cardinal tetras with preferably an open swimming area. There should be some floating plants in the aquarium because which will provide ideal places for cardinal tetras to hide. They do not like bright lights so the lighting in the aquarium should be moderate and the aquarium should not be in the direct sunlight.

As tetras, on the whole, are schooling fish, cardinal tetras are not an exception. While buying them, you should buy at least a group of 7-10 so that they will be happy to live with their friends. The beginners may think that this number is large but considering their easy maintenance and feeding habits, the whole group will be very colorful and lively for your aquarium.

The breeding of cardinal tetras is difficult because the fry are very delicate and sensitive to the environment and very few of them can survive. In addition, the adults eat the eggs and also the fry so it becomes very difficult for the beginners to protect the young ones.

However, those who want the enjoyment of a colorful and lively aquarium without many efforts then always go for cardinal tetras.

Hyphessobrycon pulchripinnis - Zitronensalmler...

Glassily transparent, the lemon tetra (hyphessobrycon pulchripinnis) could appear to be just a sunbeam flashing through your community tank if not for background elements like plants and driftwood. Another member of the large characin clan, the lemon tetra has a fairly elongated body like its smaller relative the neon tetra and like neons and other characins, the lemon tetra does best if kept in small schools of six to eight fish.

One of the most distinguishing features of the lemon tetra is their large eyes. The upper part of the lemon tetra's eye is brilliant red, which is a sharp contrast to the yellow pastels it displays in its body colors. Actually, though, the lemon tetra is quite colorful on close inspection. Body coloring is a delicate pale yellow, flanks are silver, and the leading edge of the anal fin is shiny-bright-yellow and sharply divided from the other rays, which are black. 

In the male, the rest of the anal fin is broad and fringed in black, a characteristic that is missing in the plumper female. As many male characins do, the male lemon tetras also have tiny hooks on their anal fins. Both males and females have the tetras' characteristic adipose fin, which is also pale yellow in color.

Although omnivorous and able to exist on a diet of flaked food, the pale yellow color of the lemon tetra displays best if the fish's standard diet is well supplemented with live treats. The lemon tetra is an egg-scatterer. However, breeding can be tricky since females often have a problem expelling their eggs and after spawning, the lemon tetra like many others of its species is quick to cannibalize its eggs if not removed from the breeding tank. However, eggs will hatch in about 24 hours after spawning. Fry should be fed alive diet and if they survive, they'll be about two inches long as adults.


GLOWLIGHT TETRA - A Superb Fish to Keep in Community Aquariums

English: Tetra Glowlight Hemigrammus erythrozonus
Tetra Glowlight Hemigrammus erythrozonus (Photo credit: Wikipedia)
Originating from river Essequibo in Guyana, Glowlight tetra fish comes from very turbulent water. The river runs through mountains and forests. In its journey into the Atlantic Ocean, the river has many waterfalls and rapids. Naturally, the fish is accustomed to staying in water currents.

The maximum size of Glowlight tetra fish is about 1.4 inches. It has a silvery color for its body and there is one bright stripe running throughout the body right from the snout to the tail. The color of the stripe is usually red but sometimes you can find Glowlight tetras with an orange stripe. The fins are normally transparent, but sometimes you can find silvery fins also. Innovative breeders are successful in bringing out color variations on their body. So these days you can have Glowlight tetra fish with the golden body also!

The fish is mainly described as schooling fish and it should be kept in a group of at least six. If you are able to keep a bigger group, the fish will be able to live happily. However, keeping only a single one or a pair is never desirable. The fish will develop stress and it will get sick. The life of the fish will also be shortened as they do not feel safe and they will not swim freely. But if they are kept in a bigger group, they will always be active and will show natural behavior.

Glowlight tetra fish usually tend to stay in the middle part of the aquarium, slightly above the bottom. However, when they are fed, they will immediately come to the surface of the water and try to grab the food. They are happy eaters and if you keep them well, they can live up to 4 to 5 years.

If you are planning to keep them in a community aquarium, you should always select nonaggressive species to stay with them. Cardinal tetras are good partners for Glowlight tetra fish. The color combination of both the fish will make your aquarium really beautiful. Cardinal tetras will form their own group and they will swim along with Glowlight tetras all the time. This will make your aquarium great.

Regarding keeping conditions of water in the aquarium, there are no complicated requirements. The temperature of the water should be within a range of 74-84 °F and the pH level of the water should be between 6.0 to 7.5.

If you are able to set up a medium-sized aquarium that is fine for Glowlight tetra fish. An aquarium of 10 gallons is good for them but if you are able to provide an aquarium of about 25 gallons that will make their stay comfortable. You should try to replicate the natural living conditions for them including a lot of plants with fine leaves, a good area for swimming and continuously flowing water.

The lighting of the aquarium should be moderate and the color of the substrate should preferably be dark.

Regarding their food, they love to eat worms and plants. However, they will be happy to eat food flakes as well as boiled vegetables.

Glowlight tetra fish are available easily from a lot of pet shops and they are not very expensive. So they are ideal for beginners as well as experienced fish-keepers.

NANNOSTOMUS Fish Care - 3 Exciting Varieties

Red Pencilfish (Nannostomus mortenthaleri)
Red Pencilfish (Nannostomus mortenthaleri) (Photo credit: Wikipedia)
Get a good idea of how to look after the variety of fish that you buy. Today you get aquariums with all kinds of electronic gadgetry to help you look after your fish. However, you could still use something like a test kit and maybe additional items to help take care of your aquarium. It is true that different varieties of fish may require different kinds of attention. Still, some of them need similar care. It is imperative that you know what kind of fish require what specific kind of attention.

The Nannostomus varieties include the Eques, the Marginatus, the Unifasciatus, the Trifasciatus, and Beckfordi species. The Nannostomus Eques belongs from the Amazon region. These fish are widely known as the Nannobrycon Eque, or the Poecilobrycon. It is also called the tube fish and it can grow up to 2in. in length. The Pencilfish is yet another name for the variety. It has a long snout and it swims in the aquarium at angles. They are peace-loving creatures and do not like too many changes in their habitat. They prefer a water temperature of around 78 to 80 degrees Fahrenheit. The male of the species is generally slimmer than the female.

A. Nannostomus Marginatus
This is usually called the dwarfed Pencilfish. It belongs to western Guiana. They are quite small and do not grow more than about a quarter inch in length. But their colors make them look bigger than they really are. They have stripes of black and a sprinkle of red on the fins.

B. Nannostomus Unifasciatus
This one is also called the tail eye Pencilfish. Some people call it the One line Pencilfish. Its home is in the Amazon region. They grow to about 2in. length. These are some of the most colorful fish that you will ever come across. It has lower lobes, which are nicely colored with spots. When it enlarges its fins, it is a sight worth seeing.

C. Nannostomus Beckfordi
This fish is also a friendly creature much like it's cousins. It prefers water conditions similar to the other categories mentioned above. Whether it is good for breeding or not has not been determined yet. However, you could always make your own studies and research. It has widely come to be known as the Beckford's Pencilfish and also the Golden Pencilfish. It grows to around 1.75 inches and did this too belongs in the Amazon region. They are fragile fish and are great for the home aquarium.


Fact Sheet: CARDINAL TETRA - Paracheirodon axelrodi

peace with my buddies
Photo  by Leino88 
The Cardinal Tetra, Paracheirodon axelrodi is closely related to the very popular Neon Tetra Paracheirodon innesi and the Green Neon Tetra Paracheirodon simulans. It is less closely related to the hundreds of other tetra species. The Cardinal's specific name, axelrodi was given to honour the great fish expert, Herbert R. Axelrod. The Black Neon Tetra Hyphessobrycon herbertaxelrodi is not a very close relative of the Neon or the Cardinal. Its name is misleading.

The Cardinal Tetra's maximum length is a little over 4cm. Cardinal Tetras are a peaceful community fish suitable for keeping with other small, peaceful fish. Common companions include other small tetras, small Rasboras, Guppies and other livebearers like platies and swordtails, as well as Corydoras catfish.

Cardinal Tetras are often kept successfully with discus and seem better able to tolerate the high temperatures. Discus fish need than Neons. They are also a little bigger than Neons and less likely to be eaten by a discus.

Fish I would not recommend putting with Cardinals include all large fish, Buenos Aires Tetras and Tiger Barbs. I have known cases where people have successfully kept Cardinals with some of the fish I just listed, but there is some danger if you attempt it. If you keep Angel Fish and Cardinal Tetras together, you need to accept the likelihood of the Angel Fish growing big enough to eat the small fish.

The Cardinal Tetra comes from the upper reaches of the Amazon River. This is a tropical area and is a tropical fish. Cardinals should have heated water, unless they can be kept in a room that never gets cold. The obvious way to heat the water is with an aquarium heater. I suggest setting the thermostat to 24C.

It comes from acidic and extremely softwater. This is the ideal water for them and is probably essential if you want to breed Cardinals. However, they can be kept successfully in water with Ph ranging from 5.0 to 7.4. They will tolerate moderately hard water for living in, but extremely softwater is needed if you want to attempt to breed them. When they are kept with mixed other fish in an aquarium, I recommend a Ph of about 7. Some cover like plants are beneficial for the fish.

Cardinals can be kept successfully, even in the strange water that comes through the taps in the Adelaide Hills as long as you get rid of the high level of Chloramine and adjust the Ph.

Like many tetras, the Cardinal is a schooling fish and I recommend that at least five be kept together. A school in an aquarium is a surprisingly beautiful sight. When it is dark, this fish losses its bright colours, but quickly regains them when it gets light again.

Although Cardinals will school with their own species for preference, if there are too few Cardinals to form a school they can school with Neons.

Like many fish, Cardinal Tetras are naturally omnivores and will eat a wide variety of food in the aquarium. Flakes are the normal basic diet for them. I find they also benefit from dry fry food. They enjoy small live food like small wrigglers (mosquito larvae) and small crustaceans like daphnia. Frozen foods like blood worms are also good. Remember they are small fish. DO NOT OVERFEED.

The Cardinal tetra is similar to more frequently kept Neon tetra but is much more difficult to breed in aquariums. Since both species look similar to each other at first glance, they are sometimes mixed up with each other and the Cardinal tetra is sometimes erroneously referred to as "red neon tetra". Telling them apart is however not very difficult. Both species have a characteristic sparkling blue line that bisects the body, and under this line, you will notice a red lateral stripe. If this red coloration extends only halfway to the nose of the fish, you know that it is a Neon tetra. If the red coloration instead extends much longer, you are looking at a Cardinal tetra. The red coloration of the Cardinal tetra was thought to resemble the long red robes worn by cardinals, hence the name. The scientific name of this species was given to it in honor of a highly regarded ichthyologist.

Since the Cardinal tetra is quite difficult to breed in aquariums, a majority of the Cardinal tetras in the aquarium trade has been wild caught. The native habitat of the Cardinal tetra is the upper Orinoco and Negro rivers in South America, where the water is acidic and very soft. Fortunately enough, the Cardinal tetra is very prolific in the wild and is not considered an endangered species. It is only reluctant to breed when kept in aquariums. In the wild, it is uncommon for a Cardinal tetra to grow older than one year. When you keep Cardinal tetras in aquariums without any predators around, you can, however, make them survive for several years.

The Cardinal tetra can be kept in community aquariums with other peaceful species that appreciate the same water conditions. It will usually stay smaller than 2 inches in length and a group of Cardinal tetras does not need a large aquarium to do well. This species is rarely found in beginner aquariums since it is quite scarce in the aquarium trade, but it is not overly sensitive and a dedicated beginner aquarium keeper that is prepared to monitor the water chemistry and perform frequent water changes can usually make his or her Cardinal tetras thrive. It is especially important to keep down the level of nitrate. The Cardinal tetra is a schooling fish and keeping at least ten specimens is recommended, since this will make the fish less shy and stressed. Cardinal tetras are also much more beautiful to watch when they form a big school, and living in a school makes them display a much broader variety of natural behaviors.

When you set up an aquarium for your Cardinal tetras you should ideally try to make it similar to the native habitat of the fish. A well-planted aquarium that contains floating species is recommended, but you should also leave an area open for swimming. The water should be acidic and very soft. Keep the pH in the 4.6-6.2 range and the d G H under 4. Cardinal tetras can adapt to harder water and even alkaline conditions, but they will be much more sensitive and prone to illness. The recommended temperature range is 73-81° F (23-27 ° C) or even warmer.



Neon Tetra Photo: Wikipedia
Cardinal tetras are beautiful fish because of their bright red color. They are very popular among the fish keepers. However, their cousins Neon tetras have shiny neon blue color and they are also attractive. So sometimes it becomes difficult for the fish-keepers to make a choice between them.

Neon tetras are inexpensive and sturdy fish ideal for beginners. As they have a good temperament, they fit well in a community aquarium. They can grow only up to 1 inch and they do not have any eating habits.

Cardinal tetras will grow up to 2 inches and they are expensive because their breeding in captivity is very difficult. They need to be imported from the South American region.

As neon tetras are hardy fish, they can tolerate variations in the living conditions. If there is any major change in the temperature of the water or the ph level, they will try to cope up with that environment. Out of the whole family of tetra fish, neon tetras are the toughest. On the other hand, cardinal tetras are very sensitive to the conditions of water and a slight change in the conditions of water may affect them in a big way.

Both cardinal tetras and neon tetras are schooling fish and the need to live in a group. When you decide to keep any of them, you should buy a group of at least 10. If they are kept alone, they will get stressed and will get sick and may die.

Both these species can eat any type of food offered to them. They love to eat live food but at the same time, they can eat boiled vegetables and flaked food. Both of them can eat small insects and worm which are present in the water.

However, both of these species love to remain in the middle level of the aquarium. So when you decide to keep both of them in one tank, there will be problems. Even though your aquarium is large, if both of them want to occupy the middle area, there will be territorial problems. In addition, there will be problems during the breeding periods of neon tetras. Their eggs may be eaten by cardinal tetras. So it is better to keep only one of them in the aquarium.

It is a difficult decision to make. However, here are a few guidelines for you:

1. If your budget is limited, cardinal tetras will be expensive for you. So you should go for neon tetras.
2. If you are a beginner, it will be very difficult for you to keep ideal conditions of water in the aquarium all the time. Even a slight variation in the conditions may hurt cardinal tetras. So you may select neon tetras to start with. Later you can think of keeping cardinal tetras.
3. However, if you have some experience in fish-keeping, and you want to show off your aquarium to your family and visitors, you can select cardinal tetras. Their beautiful bright red color will shine against appropriate background of substrate and decorations.

It is difficult to breed neon tetra is in captivity but it is almost impossible for the experienced breeders to try for cardinal tetras. Considering their huge demand, some experienced breeders may try to sell you something which they will label as neon tetras or cardinal tetras. The fish will be cheaper but may not show their bright colors and they may look dull and inactive. Most of the times, they may die soon after bringing home. So you should be careful while purchasing any of them. You should speak in details to the staff of the pet fish store and if possible consult your friends before you buy.

SILVER DOLLAR Aquarium and Fish Care

A photograph of the Silver Dollar (Metynnis ar...
A photograph of the Silver Dollar (Metynnis argenteus). (Photo credit: Wikipedia)
Silver Dollar is one of the Metynnis Lippincottianus fish species. Metynnis Lippincottianus or Silver Dollar fish comes from Amazon Basin and grows up to five inches in size. The Silver Dollar is one of the popularly sold fish on the market. The fish has a strong pressed oval-shaped body. Silver Dollar fish are passive creatures, which like to live peacefully with other fish. 

In addition, the fish prefer to live in a large tank and reside with their own species. This fish has a natural side, which promotes him to destroy plants, which include Vallisneria plants. In a couple of days, you will be purchasing new plants. Therefore, it is important that you feed this fish when he is hungry. The little fellers like lettuce, sprouts, spinach, as well as meaty dishes. 

Metynnis Lippincottianus tend to enjoy moderate soft water conditions, as well as faintly acidy waters. Metynnis Lippincottianus fish will breed, as well as produce hundreds of eggs at a given time. The eggs usually hatch in a few days. Prepare for an army.

Shreitmueller or Metynnis hypsauchen originates from Amazon Basin areas. The fish grow 6 inches in size a have strong pressed oval-shaped bodies. The fish has behaviors similar to the Metynnis Lippincottianus; as well, their feeding patterns, habits, etc are similar. In addition, Metynnis hypsauchen has similar water condition demands as that of the Metynnis Lippincottianus fish.

The only significant differences between the Metynnis Lippincottianus fish and the Hypsauchen is that these fish lay thousands of eggs in one hatching. This requires that you prepare for a larger army, which the hatchlings must have a water temperature of 82 degrees.

Gymnocorymbus Ternetzi 
This fish group is commonly known as the Black Tetra. The fish is also known as the Petticoat and Blackamoor Fish. Gymnocorymbus Ternetzi comes from Bolivia, Argentina, and Brazil and grows up to 2 inches in size.

The fan-like fins, anal, and dorsal is often black. The jet-black species have 2-vertical black coated bars that line the silver sides or flanks. This is a good tank fish; however, the fish have instincts to nibble at other fish fins. The fish enjoy dry foods, as well as a variety of foodstuff. Gymnocorymbus Ternetzi does not place a high demand on the water conditions. The water temperature should remain at 68 degrees or 70 degrees Fahrenheit. You can breed these fish in moderately hard waters or neutral waters. The fish lay hundreds of eggs, which hatch in one day. Hatchlings require infusoria foodstuff at the start.

Pristella Maxillaris otherwise known as X-ray fish, Pristella, or Goldfinch come from the Northern South American areas. The fish only grow around 1 and a half inches in size. Pristella has transparent bodies. This fish is ideal for commune tanks since the fish is passive in nature.

Pristella Maxillaris will feast on all foods and require water conditions or temperature set between 72 degrees and 78 degrees Fahrenheit. This fish lays up to 500 eggs and is one of the easier to breed specimen. The hatchlings are usually delivered in one day.

In all, you will find a wide array of fish at pet stores. Each specimen has its own needs, yet many are similar in nature. Additional fish include the Hemigrammus Erythrozonus species, Hyphessobrycon Flammeus breeds, and the Paracheirodon innesi. Hyphessobrycon pulchripinnis is space available. If you are just starting out avoid the Piranhas and the Characin species. The carnivores will eat other fish, as well as fleshy dishes. Piranhas are better left for fish experts to maintain.

Freshwater fish holding would be lamentably poor without the brightly colorized beautiful Neon tetras. Small green, profane or crimson fish swimming in freshwater tanks would most probably be the ever-popular Ne tetras. These fish are naturally found out in the lakes in South America or East Peru.

Ne tetras are hence popular among aquarists because they are hardy fish. They are peaceful fish and seldom nip at each other or any other fish in a community cooler. However, atomic number 10 tetras are schooling fish and these fish are happiest if they are in a schoolhouse or in a group of 5 or more. Schools or groupings make the fish experience really good. Atomic number 10s are likewise very active fish and they flit about a lot in the tank. This is a joyousness to check.

Ne tetras can dwell for rattling long periods if they are given proper care. 10 years is a potential lifespan of the shipshape Ne tetra. Neons unremarkably reside the middle or bottom levels of a storage tank and can grow up to 4 atomic number 96s. in length. The ph scale of the water should ideally be between 5.5 and 7.8. Their favorite water temperature is within the reach of 68 levels F to 75 levels F. The fish are generally spindle-shaped. The belly area is a bit lashed out especially among the female persons. The nose is blunt. A wide violent band runs down the body of the Ne tetra and extends up o the Caudal fin. A grim band that runs from the upper portion of the center premises this. The side above this is olive green while the lower side is silvery. The anal fin is mostly transparent. This prominent collage of coloring materials, peculiarly the counterpointing reddened and green, stimulates the Ne tetra one of the most popular and colored fishes in the freshwater aquarium.

Dark substratum and curbed lighting is the most suited for neon tetras. Putting in sets of floras is besides very good for the timid and active atomic number 10s. Some driftwood is too advisable. The tetras should not be kept with bigger fish, or they will end up becoming tiffin. Since neon tetras are therefore democratic, they have found out to adapt themselves to a wide range of habitats. But, ferocious breeding of the tetras to issue adequate fish for the burgeoning demand for atomic number 10 tetras has led to the loss of their native robustness. New fish are very delicate and chances of losing fish just after they are introduced into a cooler are very high. Withal, erstwhile the Ne tetras have shown themselves, they get along quite an intimately without too much difficultness.

Neon tetras are ball scatterers. They are a bit unmanageable to breed in enslavement. This is by and large due to an unsuitable body of water experimental conditions. Eggs of the Ne tetras appear to be light sensitive, hence Ne tetras postulate to be placed in a dark berth, as they get ready to spawn. A 2 3 inch layer of rock and some fine rough textured live floras are the best medium for spawning. The water temperature should not be above 75 points F. A hat should be kept on the tank at such a time, as the fish be given to bound very high during this period. While breeding the nes, it is necessary to look for the healthiest breeders. Merely young fish should be used for breeding determinations.

They should be coursed some live solid foods especially 2 3 days before breeding. These breeders have to be gone away in a spawning medium for about a day. The testicles are usually liberated ahead of time in the morning. The ballocks are well-nigh transparent and scantily stick to the surface of plants. The eggs will incubate in about 22-30 minutes. The small fry is very hard to spot at once. But, as soon as they get free to swim in 3-4 days, they will be seen very clearly, though they are yet very small. The stockbreeders should be removed as soon as the ballocks are spotted. As soon as the tike is loose swimming they should be preyed with infusoria. Ne tetras that breed in incarceration are not very fertile. A good spawn would consist of about 40-55 tyke only.

Neon TETRA Facts

"NeonTetra" by Corpse89  Licensed via Wikimedia Commons.
Neon tetras or Paracheirodon innesi are members of the family Characidae. Characidae is commonly referred to as Characins. Neons are natives of southeastern Columbia, eastern Peru, and western Brazil, including the tributaries of Solimoes. They can be found in black water or clear water streams

Neons are an all-time favorite among freshwater aquarium owners. In any given mouth approximately 1.8 million neon tetras are exported to the US alone. Their petite size most certainly contributes to their popularity. They rarely exceed an inch and a quarter in length. You can keep an entire school of them in an aquarium no bigger than 5 gallons. They are the perfect choice for desktop nano tanks.

These dazzling little beauties will add brilliance and color to any aquarium. The iridescent blue horizontal stripe that runs just above their spines almost glows under aquarium lights. Just below the blue, a second bright red stripe runs from mid-body to the base of their tail. These radiant colors are transposed against a translucent body. Their fins are transparent. You can see right through them.

There is a slightly more colorful member of the tetra family. Neons and cardinal tetras look very similar in appearance. Put them in the same aquarium together and most people wouldn• t be aware they are two different species. Both have metallic neon blue upper bodies and a brilliant red stripe in the center of their bodies. This stripe is found mid-body running to back the tail in neons. The stripe runs the entire length of a cardinal• s body.

Neons are by nature a skittish species. They spook rather easily. They are also very small fish that could easily be perceived as a source of nutrition by larger species. They do however make excellent community fish if you take these factors into consideration. An abundance of plants and or rockwork will provide sufficient hiding place and help them feel confident in their new surroundings. Avoid keeping them with species that will grow large enough to ingest them. Following these simple rules will keep your neons healthy, happy and most importantly, alive!

Neons are mid-tank swimmers. They are shoaling fish. Shoaling fish do not cope well when isolated from other members of their own species. Many will not survive in solitude. It is advisable to have at least four neons in your aquarium. This will help to ensure that they adjust well to their new environment.

There is yet another factor to consider when deciding whether these fish are right for your particular aquarium. Tetras are notorious fin nippers. The more neons you have together, the higher the likelihood that this will become a problem. Long, flowing fins like those found on a betta fish or a fancy tailed guppy will most likely prove to be a taste treat tempting to pass up.

This is a hardy species. These omnivores have an extremely high survivability rate in captivity. They are not finicky eaters. A good quality flake food for omnivores is the perfect staple for their dietary needs. The average life expectancy of neon tetras in captivity is 5+ years.

The exportation of species for hobby fish trade began to boom shortly after World War II. Neon tetras were among the first species to be sold under the label, tropical fish. Their introduction to Europe and the US helped to fuel what is now the multi-million dollar aquarium trade industry. At one time these fish commanded an insanely high price tag. Commercial fish farms have since brought their price well within a range of the average aquarium enthusiast and made them one of the most popular fish in the world today.

Piranhas have red throats, razor-sharp teeth to rip flesh with ease, and silvery gold flesh (red-bellies have red bellies, of course). Piranhas are native to South America and Guyana and it's against the law to bring them in and out of most countries. They are quite dangerous and aggressive fish since they reside in schools, which has a tendency to promote a competitive environment.

When planning a piranha aquarium, fish size should be regarded first. Grown piranhas have been known to develop to two feet long in a big enough tank. Piranhas are in addition group swimmers, which means they'll need room to roam. Strive to provide two gallons per each inch of piranha fish. An aquarium six feet long by two feet by two should allow ample hideouts. A minimum fifty-gallon aquarium is recommended.

Piranhas (Pygocentrus (Serrasalmus) nattereri) are very sloppy eaters. Ten to fifteen percent water switch-outs every seven days will ensure waste not trapped by the filter system is taken away. Regarding filter systems, almost all piranha aquariums will need at least two devices to manage the process, especially if the aquarium is fifty or more gallons. Nitrate concentrations, which have harmful effects on piranhas particularly, should be monitored directly. PH levels ought to stay between six and one half and 6.9 to copy those of the Amazon where piranhas came from.

Water degrees in a piranha enclosure should be about eighty degrees to encourage piranha movements. Many piranha owners employ additional water pump devices to prod piranhas to swim in opposition to the waves as in the River of the Amazon. The practice additionally promotes metabolism levels, stimulating eating habits.

For decoration, it's preferable to keep the fish tank low lighted to encourage piranhas to venture into open water. Man-made fauna is recommended. Any rocks and synthetic centerpieces will need to be tightly fastened, seeing as strong piranhas will hurl pieces around, potentially breaking the glass.

Piranhas' diet consists completely of proteins. Living meaty rations such as non-fatty poultry or beef and fillets of fish may be administered daily or bidaily. Feeder comet fish are a non-expensive choice, but piranhas will dine on practically any variety of meat. Experiment to find what yours favor. Whatever you do, don't leave your fingers in the water too long!

Obviously, piranhas are aggressive fish, which makes your choice of tank mates relatively slim. However, some other aggressive fish can co-exist with them. For example, tetras, cichlids, Oscars, pleco catfish and pacus. These fish are by and large excellent defensive fish, while the plecos have tough outer shells and can grow to larger, intimidating sizes. Pacus resemble piranhas and will fight back. Tetras are quick and small with sensory instincts which allow them to stay clear of piranhas. Piranhas also aren't likely to give chase to such speedy, small cohabitants. Cichlids may or may not coexist with piranhas; they have simply been known to team up against them to survive. Oscars are large and in charge and inexpensive to replace if they're slurped by a fat red-belly.

As a rule of thumb, don't introduce too many new experimental tank mates into your piranha tank. Add them one by one to see how they adapt. Whatever you do, don't get too attached to them until you know they're going to make it!
