Mollies come from Poecilia spp. and the Poeciliidae family. The Mollies are one of the favorite tank fish since the fish is similar to the swordtail fish. The swordtail comes from the Xiphophorus helleri group. The molly, however, does not have a swordtail, rather a larger fin, known as the dorsal. The fish has a variety of shapes and it reaches up to 4 to 4 ¾ inches in size. The males only grow to 3 1/3 or 4 inches at most. Mollies male and female counterparts differ in color, size, and gonopodium. The fish can live in extreme wide-ranging environments and will suit in estuaries habitats. The water temperature desired of the molly is 72 degrees, not succeeding 82 degrees Fahrenheit. Mollies also prefer hard water, which the pH level should be set at seven or eight. The fish will reside in hard waters, which salt is needed. Mollies enjoy house furnishing, lights, well-planted areas, thin layers of humus, and so on.


Mollies will feed on vegetables, including spinach as well as algae. The fish are omnivorous in nature. Mollies have a biological lively nature, which the schooling fish desires constant water flow. The fish are livebearers and breed successfully providing plenty spawns. In addition, mollies are sociable, yet the fish should be kept in community tanks where large schools exist.

Guppy fish listed under Poecilia reticulata is kin to the family of Poeciliidae. The fish comes from the waters in Guyana, Venezuela, Brazil, Trinidad, and Barbados. The environment desired is still, flowing waters. The fish prefer water temperatures at 68 degrees and no higher than 75 degrees Fahrenheit. The pH level should not succeed eight, nor go below seven. The water preferred is hard water, which the fish can live in extreme hard water conditions as well. Tank: The fish prefer illuminated tanks with plenty of furnishing. You should store the fish in a medium tank and provide them rich vegetation and plants. The fish will eat all sorts of foodstuff. Biological nature; The biological loose school natured fish will be on the constant go, therefore he does not have time for long-drawn-out schooling arenas. The fish are good breeding fish, yet beware, since Guppy will eat their own youth. You should keep Guppy fish in tank aquariums where other livebearing fish reside.


Nowadays the aquariums are ecosystems include a wide assortment of technology advanced qualities. Air and water pollution has increased the need for aquarium life, which in accordance technology has advanced the tanks to meet the high demand of aquarists. Tanks today are constructed by technological experts, which design real water aquarium environments. Most tanks sold today, including advanced electrical circuits, plugs, filters, air supply, etc. The market is saturated with tanks that will allow you to raise or lower the water temperatures. The light switches enable you to vary in intensity, thus lowering or increasing the light production.

In addition, you have a wide array of on and off switches, which utilize mechanical timers that permit aquarists to easily adjust water temperatures and light intensity.

One advantage of tanks today is that most tanks are equipped to handle nearly all fish available on the market. The problem is all fish are different and require their own special attention. Therefore, you should never group fishes with fish that prefer to live with their own kind. In addition, seawater/saltwater and freshwater fish differ. The freshwater fish include the Tropical and Coldwater fish.


GUPPY Companions

By now, your guppies have settled into their tank and you have enjoyed getting to know and enjoy them. I imagine your confidence has soared and you have the urge to have some different inhabitants. This is where the term community tank takes its meaning. Not all fish make good companions for other fish.

The guppies are a peaceful fish and get along with other livebearers like mollies and swordtails. These small fish are covered with the big name of Cyprinodonts because they have teeth. These groups are named tooth-carps and cover both the livebearers that have live fry and the fish that lay eggs. So if you hear different names for the same fish this is the reason. Most community tanks will have the addition of catfish or suckermouth fish to help in algae control.

My favorite addition to a community tank is catfish, the very shy algae eaters that scoot from dark corner to an even darker hiding place. The catfish live primarily on the bottom of the tank but you will see them moving all-around the tank attached to the glass with the sucker mouths they possess or moving in a flash through the water. While the catfish I have are pleco‘s, they are just one of over 2000 species. The common plecostomus can live a long time, and you have to be aware that these fish can grow quite large.

They do like the vegetable matter to form the greater proportion of their diet. They will eat sliced courgette or peas with gusto! Pseudo fights for ownership of peas dropped into the tank will happen between the guppies and catfish. They will also clean up dropped food after the guppies. There are also specific foods just for the pleco and they feel very special getting these treats. These fish have wonderful personalities if they qualify as having one! I have always had bogwood in the tanks; the pleco does like these and during the day will hide or spend time on or around the bogwood. The male has more whiskers that are prominent on his snout, where the female has a more reduced number just around her nose.

glyptoperichthys gibbiceps

The breeding habits of the bristle nose pleco are interesting to see. If you have provided a cave or tube like structure for them to hide in or under, you may notice the male “sweeping” or tidying the house. The female appears to attach the eggs to the walls of what ever the adults have elected to use. The egg sacs are noticeable in that they are an orange color. This color makes them very noticeable to the fry “eating” guppies. The male will spend time causing water movement into the cave for the young.The parents seem to watch the small pleco’s but you will only know they are in your tank when you see the little fish amongst the pebbles and plants in the bottom of the tank. Guppies will eat anything they find so you will need good hiding places to read any real number of the little pleco. These are excellent fish to have in a community tank.

Two of the more popular tropical fish for beginners has to be Guppies and Swordtails.  Guppies and Swordtails are livebearers which means that their babies come out swimming.  Like most livebearers, there is not much to getting your guppies or swordtail to breed.  If you have a male and a female then you will eventually have a pregnant female.  The gestation period for livebearers is usually 28 days but can range from 20 to 40 days.

Place the male and female in the same tank together and they will soon mate. You are probably asking, how can I tell when the female is pregnant?  When a female guppy is pregnant she will develop a dark triangular shaped gravid spot near her anal vent.  This will get larger and darker as the pregnancy progresses.  While you are waiting on the female to develop the fry it's time to make sure you are prepared for the delivery.  We use plastic breeder boxes and always have without any problems.  A breeder box is a small box plastic box about 4 inches long by 3 inches wide and 4 inches deep.  There is a removable "V" shaped trap in it which serves to separate the mother from the babies.  When the mother fish has babies they fall through the slot in the "V" into the bottom of the box.  

After the mother is finished having babies, you can remove the "V" trap so that the babies have more room to grow.  Some people have had bad experiences with breeder boxes and now only use a breeding net.  It is also a good idea to purchase some real or plastic breeding grass for the top of the aquarium.  The breeding grass is just in case the mother gives birth before you have a chance to put her in the breeder box.  The young babies instinctively will swim to the top of the aquarium and the breeder grass provides a great hiding place so they won't get eaten by the bigger fish in your tank.

To feed your new arrivals you can use finely crushed flake food.  Using your fingers, you can rub the flakes into a fine powder.  Some only feed live foods such as baby brine shrimp.  Live foods would definitely be the best way to go, but for most this is simply not feasible.  Crushed or powdered flake food will suffice.  Try to feed the babies 3 very small meals per day.  You will invariably feed too much and the excess food will drop to the bottom of the tank or breeder box.  To clean a breeder box we like to take a 3 ft. length of aquarium tubing and a small bucket.  Use the tubing as a siphon to clean the bottom of the breeder box.  Be careful not to siphon any baby fish.

Try to perform 25% water changes weekly for your baby guppies.  This will aid in the optimal growth of your baby tropical fish. After a few weeks in the breeder box your new babies will soon outgrow their home and you will need to move them either to a new tank or your main tank with a divider installed. By 8 weeks old your baby fish will most likely be able to return to the main tank without a divider.  However, it really depends on the size of the other inhabitants in your aquarium.  Use your best judgement before releasing them into the main tank.

Whether you are going for that one of kind strain or if you simply find small fry swimming in the top of your tank one day after work, please be responsible with your fish.  If you have more than you can accomodate you can try trading them or maybe even selling them to a local fish store in your area.

Talk to your local pet stores beforehand to see if you can work out some sort of arrangement.  You can also use this opportunity to get your friends interested in fish.


Fact Sheet: GUPPY - Poecilia reticulata

Guppy Fact Sheet 
The Guppy, Poecilia reticulata is an attractive and normally peaceful fish. It was named after Robert John Lechmere Guppy who discovered this fish in Trinidad. He believed that this was a previously undiscovered fish. After being scientifically described, the fish was called Girardinus guppii. The common name of Guppy was given the fish.

The Guppy males tend to have a smaller body and bigger fins than the female. The fin underneath the fish in about the centre of the fish's body (the anal fin) is long in the male and is used in fertilisation. The male is capable of pointing it forwards so it can make contact with the female and transfer the sperm. In the female, this fin is triangular in shape. The males tend to be much more colourful than the females. Modern female guppies often have good colours, but the wild ones did not. Modern Guppy males tend to have purer colours, while the wild ones tend to have more varied ones. Often the wild males have more colours on each fish.

It was later found that the fish had been previously discovered by Wilhelm C. H. Peters, described and named. The fish is now usually called Poecilia reticulata. The most common of the common names is 'Guppy'. There are several other common names including 'Rainbow Fish' and 'Millions Fish'. The name Rainbow Fish is appropriate to its many and varied colours, but is misleading because of the several other fish with the same name. I prefer the name "Guppy'. However, I would note the name 'Guppy' is sometimes used for other fish. Fish I have seen called 'Guppies' include goldfish, Neon Tetras, Zebra Danios and Gambusia. This is simply misleading and can be confusing.

Guppies are native to several Caribbean islands and north western South America including Barbados, Guyana, Netherlands Antilles, Trinidad and Tobago, the US Virgin Islands, Venezuela and Brazil.

The Guppy is a popular aquarium fish. It can be kept with other small peaceful fish, including Platies, Swordtails and Mollies. It is in the same family as these fish and is in the same genus as Mollies. Other fish suitable as companions are White Cloud Mountain Minnows, Neon Tetras, Cardinal Tetras, Siamese Fighting Fish, Peppered Catfish and other Corydoras catfish, Cherry Barbs, and other small peaceful fish.

Note that many of the fish just named are schooling fish. I would recommend that these be kept in groups of at least four, and preferably more. The Guppy is not a very strongly schooling species and can be kept singly or in small groups, although I certainly prefer larger numbers. It is both the way they usually occur naturally, and they look good. A tank of the highly coloured Guppies is a beautiful sight. Males and female guppies can be kept together although if they are I suggest that at least one female be kept for each male. If you keep several males with one female, all the males want to mate with the female and do not give her much peace.

Fish I would not recommend as companions for guppies include Black Widow Tetras, Serpae Tetras, Buenos Aires Tetras, Paraguay Tetras, Red Eye Tetras, Tiger Barbs, Rosy Barbs, Paradise Fish, Galaxias, and any other fish that can be fin nippers. Larger fish are also generally not suitable companions for Guppies.

The Guppy is easy to feed. They are omnivores like most fish,and benefit from some vegetable food including algae. Guppies will eat most fish food. I suggest a good flake food as a basis for the diet, if possible supplemented with other food to give variety. Good flakes include the Wardley Total Tropical or Total Colour. As well as Wardley there are many other reputable manufacturers of fish food who make excellent foods. Other foods can include live food like Daphnia. Mosquito larvae (Wrigglers) are an excellent food. In the wild, Guppies will eat a lot of these. Their upturned mouth is well adapted to eating wrigglers. Blood Worms are related to wrigglers and are also a good food. Frozen Blood Worms are also good, as are several other frozen foods. Live or frozen Brine Shrimp are good. I also find that Guppies will benefit from dry fry food as achange.

Do not over feed your fish.
I suggest feeding once a day, but not too much. For most types of food the fish should have finished it in a couple of minutes. Guppies are good eaters and generally will get the food quickly. Larger food including Algae Wafers is also good. Because these are hard, the Guppy will take longer to eat them.

Guppies generally thrive in fairly hard, slightly alkaline, water. They can tolerate very large amounts of salt in the water. In some countries they are bred in water which is a mixture of half fresh water and half sea water. The Guppies thrive in this water, but these fish can cause problems when people put them into normal fresh water aquariums. As well as having to be acclimatised to the fresh water, the Guppies have not been exposed to columnaris disease. These fish can die very quickly in a normal aquarium unless strong treatment is done quickly. To get immunity the fish have to be exposed to the disease, and the disease cured.

Rain water is not good water for guppies although many people have used it successfully. If this is the water you have, I suggest using a rainwater conditioner (A mixture of salts). If you are using tap water (as I do), make sure you get rid of the Chlorine or Chloramine.

For a tank of mixed small tropicals, I suggest a pH of 7 and a moderate amount of salt and hardness. In most places normal tap water, with the Chlorine or Chloramine removed and the pH adjusted to 7 is suitable for Guppies, and to a mixed community. If in doubt about your tap water, I suggest visiting your local aquarium store. They should know about the local water.

The Guppy is a tropical fish. However, different strains of Guppy have different tolerances to low temperatures. I have even heard of strains that are claimed to be able to tolerate temperature down to 4Ì? C (39Ì? F). I have never encountered any of these. Once I heard of a creek to the north of Adelaide that was supposed to have a naturalised strain of Guppies. I searched for the creek. I was able to identify the creek from the description I was given. There were no Guppies in it. (Actually, there was not even any water.) Although I tried to find where the Guppies would have gone, I was unable to find any Guppies. I suspect that this was a case of mistaken identity of the fish.

As a general thing I would not suggest a temperature of lower than 18 degrees C (65 degrees F). Guppies will certainly tolerate up to at least 32 degrees C (90 degrees F), and probably higher. Although I sometimes give the maximum and minimum temperatures types of fish can tolerate, it needs to be remembered that subjecting fish to their limits is not good and you are stressing the fish very badly. Stress will leave the fish very vulnerable todisease.

I generally set the thermostat at 24 degrees C (75 degrees F) although some people prefer a few degrees higher, especially for breeding.

The modern Guppies have been selective bred for colour and fin length, as well as other external characteristics. In the process they have lost much of the original hardiness of the Guppy. The life span of the Guppy now is often no more than a year.

Pest Fish
The Guppy has been introduced to every continent except Antarctica. In some places it is causing considerable damage to the native fish of the areas it has been introduced to. You should not release aquarium or pond fish into the wild, and you should ensure that they cannot get introduced accidentally.

It is worthy of note that many of the most destructive introduced fish and other animals have been introduced deliberately, often by government agencies.

Aquarium Care for the Freshwater GUPPY

Guppies are perhaps the most popular type of freshwater fish to keep in an aquarium.  Luckily, they are fairly easy to keep as well.  Guppies are hardy fish that can adjust easily to minor fluctuations in water quality.  However, don't allow these fluctuations to become common practice, as they do cause some stress to the fish.  The water temperature in an aquarium for guppies should be kept between seventy two and eighty two degrees. The P.H. level should be kept between 7.0 and 8.2.  As you can see these specifications are much more forgiving than those for certain tropical or marine fish. 

Guppies mature quickly and usually only grow to be about one and a half to two inches long.  There small bodies and feathery fan like tails add a lot of interest to the tank.  They are just fun to watch.

As with any type of aquarium, there are three basic components to caring for the fish.  Diet is very important. Guppies should be fed very small amounts as often as three times a day.  Guppies will eat just about anything, but their main diet should consist of frozen or flake foods.  This should be especially regarded when there are baby guppies in the tank, because guppies will eat their young.  The next most important feature to caring for any fish is appropriate water regulation.  The specific temperatures are listed above, but it is also important to make frequent water changes. Usually every one to two weeks, depending on need.  If the water starts to smell or become cloudy, this is a good indication that it is time to change the water.  If water changes are made gradually, meaning change approximately one third of the tank at a time, then there is little disruption made to the fish.

Last on the list for keeping fish healthy, is to keep them happy.  Try to recreate their natural environment.  It is recommended to keep a variety of plants in the aquarium for guppies to seek refuge.  There should be about one to two inches of substrate in the bottom of the tank.  Colored rock or dead crushed coral make a nice addition to the aquarium, and may help to make the fish feel more at home.  

A few varieties of guppies are the Fantail, Flagtail, Spadetail, Deltatail and the Roundtail.  The names of all of these different types of guppies focus on the tails because they are so remarkable and unique.  The tail itself is usually about one third of the size of the whole fish.  It is possible to mix guppies with other varieties of fish. However be careful when mixing because, guppies are targeted as easy prey due to those fancy tails.  Guppies breed very quickly, usually about every three to four weeks.  They will interbreed amongst themselves, so the aquarium could very quickly become filled with many different varieties of color.  It is very feasible to have an attractive aquarium without having any other fish at all.  If you don't want the species to interbreed, simply keep them in separate tanks.
