The Basics of Keeping KOI

Koi pond’s popularity are on the rise, and the reasons are obvious. Who would not want living creatures as a part of their garden? However, Koi keeping should not be taken lightly. Koi, like any other animal, require time and money to maintain. The majority of first time Koi owners fail because they get the idea that keeping Koi is easy in some way. Do not let this discourage you though, as educating yourself will greatly improve your chances of succeeding.

It is important for you to learn all you can BEFORE you begin obtaining the things you need for Koi keeping. This way, you will not slip up and have to replace anything that you have already done or bought. Planning ahead will not only save your money, but it will potentially save your sanity as well.

It is important to learn the information for yourself rather then relying on other sources. People such as your product dealer and pond builder will have limited knowledge, but should not be trusted for a reliable source, as they are selling products, and may be bias. Plus, once you are at home with your Koi, your product dealer or pond builder may not be available to help you in the event of a problem.

Your Pond

Before ever buying Koi, you must create a proper habitat for them. This is where information from your pond builder and supplier will come in handy. However, you should not rely on the opinions of just one person. It may be a god idea to do research on your own, before you go to purchase the materials needed for you pond. Because of it’s popularity, an unlimited supply of resources can be found on the topic of Koi keeping. Visit your local library, fishery center, or research online. There are quite a few things needed to sustain a habitable pond.

When it comes to pond size, the bigger is always better. Koi have a habit of growing rather fast, so you have to consider pond size at the same time you are considering how many Koi you are going to put it in.

You filtration system is extremely important. There are 2 types of filtration, mechanical and biological. mechanical filtration relives the pond of solids such as dead algae, insects, and Koi wastes. It is important to have enough filtration to sustain the size of the pond, and the amount and size of your Koi. Biological filtration causes a nitrogen cycle, which is what removes dissolved wastes from your pond. Without biological filtration, built up waste will turn into ammonia and kill your Koi within just a few days.

Another consideration is the water quality. It is sometimes said that having Koi is literally just a side effect of having the proper water quality. To keep your Koi alive, you must have the proper knowledge on how to maintain your water quality.

Buying Koi

There are potentially thousands of different types of Koi, with about 20 different popular versions. Koi are popular because of their beautiful colors and patterns.

Your pond should be complete before you even look into buying your Koi. The size and amount of Koi you buy should be highly based on your pond. Be careful, overstocking will cause problems right away with you pond, potentially killing many of the Koi you purchase, causing you to loose time and money.

Most fish owners understand that most fish will only grow to the size of their enclosure. Koi, unlike other fish, will grow until they are the size of their specific type. You must be able to accommodate the amount of fish you purchase in the future.


Proper Winter Care for Your FISH POND Outdoors

Fishes can be wintered either outdoors or indoors. This will depend on the construction of the entire pond according to the inclination of the owner. This article will focus about things that a hobbyist can do to properly protect and care for his fishes during winter if his pond is situated outdoors.

If you’re living in a country where winter is the most prominent season of the year, better build a pond wherein a portion of it is about 30-45 inches deep.

English: Fish pond in winter

This will protect the fishes from long periods of cold spells. Even more drastic than cold water is the building up of gasses which are toxic in a pond that is iced over completely for a certain amount of time.

Therefore, it is mandatory that a part of the pond’s surface is kept open to enable the pond to circulate air that results to the disposal of deadly gasses and adds oxygen. You can accomplish this by:

a. Aerator. 
This is a large air stone that is operated by an aquarium air pump which can constantly create a small opening inside the ice. Unfortunately, placement is quite critical and hard to be arranged precisely.

Ideally, the aerator should be placed halfway measuring from the deepest part of the entire pond and should be monitored frequently. Chances are, if the aerator is placed too near from the surface, it has a tendency to freeze, if placed deeper, it can chill the entire pond.

b. De-Icer or Heater.
There are different kinds of de-icers that can be safely used for performed ponds, liner or even in  concrete. Out of the use of electricity, a puncture can be made through the iced pond where it serves as breathing hole for fishes.

Sometimes, the most efficient de-icers or heaters can produce an ice-free pond even if the winter weather is overwhelming.

c. Water pump. 
Same limitations to an aerator, a water pump can provide an opening on the surface of the pond but with several conditions. One condition is that the pump must be mounted on the deepest part yet should be far enough from the bottom to avoid water circulation and far enough from the surface so that it wouldn’t solidly freeze. Regularly inspect the pump because it can freeze solid or run dry, these can destroy the integrity of the pump.

Covering the pond can be helpful for the fishes and the devices used. It can protect the pond from extreme coldness and will reduce the amount of electricity that your heater needs. Although, the cover must always be raised to enable gas exchange and prevent toxic substances to reside in the pond. The structure would turn out like a wooden frame is built over the pond at its surface then it will be covered with plywood. Insulating materials can follow. The covering must possess sturdiness to withstand the long days of snow accumulation.

Last concern is feeding your fish. Actually, you can drop this idea for even if your pets seem to be quite interested, they will just ignore the food that you’ll give. This is because during cold days, metabolism can be quite sluggish. Although, to prevent starvation, you can supplement them food that can easily be digested like the ones that are made from wheat germ.

Proper care of your pond fishes during winter can be crucial to your pets especially when it is located 


Chilled Out KOI: How Koi Survive Frozen PONDS in Winter

If you live in a northern climate then chances are good that you see snow and ice as does your koi pond. Its natural to worry about your koi during the winter periods, especially if they have been around for years and years. Fortunately, koi are adapted to dealing with cold temperatures and an iced-over pond. They have a few tricks up their "sleeves" to deal with the inevitability of ice cold water.

Regulating Body Temperature
Thermoregulation of animals or how an animal regulates its body temperature can be a confusing subject. For example, within the subject of thermoregulation there is:

- Ectothermic
- Endothermic
- Mesothermic
- Heterothermic
- Homeothermic
- Poikilothermic
- "Cold-blooded"

There's a lot of variations in the world of temperature regulation in animals but to make it more straightforward for koi owners you should know that your fish are ectothermic,which means that their internal body temperature is governed strictly by the ambient temperature (or in this case, the water temperature). So that must mean that all fish are ectotherms, right? Not necessarily. Unfortunately, biology is not always consistent.

For example, the bluefin tuna and some sharks create internal heat from muscle activity yet are still largely affected by water temperature which puts them in a category known as mesothermy. Furthermore, the term "cold-blooded" is actually not all that accurate. A "cold-blooded" lizard in the hot desert sun can achieve an internal temperature greater than that of humans. So in everyday conversation its just easier to refer to mammals and birds as endotherms and just about everything else as ectotherms.

Biological Activity and Temperature
You have probably noticed throughout the seasonal changes that as the water temperatures get colder your fish start to become less active. As a result, they require less food and at somewhere between 50 and 40 degrees F they stop eating all together. Ectotherms are able to pull this off because they don't have to maintain a certain internal temperature and, in fact, they can get away with using as little as 10% of the energy of what a mammal would need. As temperatures fall, the rate of internal biological activity decreases which includes things as basic as how fast a muscle can twitch. This concept in biology is known as the Q-10 coefficient.

Planning for Winter
There's not much activity going on with your fish, on the inside or outside. They don't need food and not as much oxygen however its still a good idea to keep some of your pond unfrozen with a de-icer for gas exchange (and some pond owners will run aeration all year long).

One of the things your koi will do is try to hang out in the warmest part of the pond and that will subsequently be the deepest part. In general though, its a good idea, when designing/building a koi pond, that you make it at least 3 feet deep to avoid the possibility of total pond freeze. Another thing you may want to keep in mind is that adding salt to your pond before winter will lower the freezing point of water and artificially cause your water to reach a super low temperature which can potentially harm your koi.

Koi in Dormancy
So what exactly are they doing under the ice? Sleeping? Playing cards? As with thermoregulation there are a lot of different ways to go inactive during winter (or periods of less-than-ideal conditions).
There is:

hibernation in mammals
brumation in reptiles
diapause in insects and
aestivation in invertebrates

but ultimately your koi under ice are in a state of dormancy. Essentially, they are simply "chilling out" in a state of super decreased activity and metabolism while waiting for spring. Perhaps you don't get to enjoy your koi as they mill around under the ice but just think of the money you are saving not buying koi food!

Winterizing Your KOI POND

Winter is coming, and this will be the first Winter that you go through with your Koi pond. Think of Winter as a down period for your pond, as less events happen during Winter then any other time. However, there are special precautions that you need to take before Winter arrives, to ensure that your pond and fish survive.

English: Ornamental fish pond One of the ponds...
Ornamental fish pond -  The net over the water is essential to keep
the fish safe from marauding herons. (Photo credit: 

Clean Up- Take about a weekend to completely go over your pond. Clean up and unwanted bulk material in and around your pond. Inside your pond, clean up all leaves, slit, and other material from the bottom. Also, remove any plants or flowers that will not make it through the winter. Around the pond, clean up anything that can blow into your pond, as you are not likely to notice this debris until the end of winter. Taking the time to make sure that as much debris is removed as possible will prevent potentially harmful bacteria and parasites in the future.

Stop Feeding- You must remember to stop feeding your Koi during the winter. When fall begins and the temperatures hover around 55 to 60 degrees, only feed once a day.  Once the temperatures drop below 50 degree for the first time, stop feeding completely. Even if the temperature goes above 50 degrees, still reframe from feeding your fish. The majority of Koi, when healthy and the temperature is above 50 degrees, take at least four days to completely digest food. If you mistakenly feed your fish to late the food will not digest and will end up killing your fish. Do not mistake you Koi as hungry when they open to their mouths to you. This is more of a learned reflex then hunger. If you are concerned about not feeding them, remember that fish eat other things besides the food you provide them, especially if your pond contains a large amount of natural plant life. If they are at all hungry and you are not feeding them, they will fill up on this.

Check Up- Do you seasonal check up on all your equipment. This includes everything from your filtration system to your store of preventable medications. Since the majority of ponds in the world lie dormant during the Winter, you are less likely to be able to find the products you need. Make sure your emergency kit is ready and up to date, which should include medications, bags, nets, and your water testing kits.

Prepare For Cold Weather- Prepare for cold weather by investing in the items you will need during the summer. Koi have been known to withstand constant temperatures as low 39 degrees, and temperatures slightly lower then 39 degrees, for short periods of time. When buying a heater, remember to research what size you will need to adequately heat your pond during the winter, otherwise ice will still form, causing potentially dangerous amounts of gas in the water, due to it being trapped under the ice. In extreme events, it may be a good idea to have an emergency tank inside available.

Turn Off All Water Sources- In colder temperatures, your heater will be working hard to maintain a water temperature suitable enough to keep your fish alive. If you have water features such as waterfalls, streams, or constant moving fountains, make sure to turn them off during Winter. These features will circulate water, and constantly bring new, and cold water into your pond. With these switched off, the only water that your heater will be responsible for is the standing water in your pond.


KOI'S Past and Future

English: Koi, ornamental fish. Cyprinus carpio...

Koi, or Nishikigoi, are quickly becoming popular in the United States. However, few know of thier origins. 

The first Koi were produced by breeding Carp such as the Asian and German Carp. After years of selective breeding, various color mutations started showing up. The first color patterns were recorded as early as 1805. Today, there are literally thousands of color variations available. The most popular colors found are white, silver, yellow, orange, red, black, blue and green. Combined with the patterns available, the possibilities are almost endless. Each noticeable pattern and color have their own names, which are typically as unique as the color they are referring too. Favorite types vary by country and location.

Koi are raised for purchase in countries like Japan, Singapore, Israel, and in the warmer American states such as Nevada and California. Koi can be purchased at most local pet stores. If they do not have stock on hand, typically they can be ordered. Ordering Koi has its advantages and disadvantages. You have more options when ordering Koi, since you do not have to pick from the stock on hand, but the disadvantage lies in the fact that you will not be able to pick specific Koi.

Koi, unlike most other fish, will continue to grow until they reach their breeds dictated size, no matter the environment that they are in. Baby Koi can be found as small as 3 inches. Jumbo Koi have even been know to reach lengths of three feet or more. The most common size found is around two feet in length.

Koi are omnivorous fish, which means they will eat both meat and plants. This means that their diets are very versatile. Koi will eat pretty much anything that you put in the pond with them, no matter if it is good for them or not. Since Koi do not have a sense of what is bad and good for them, as their owner you must control their diet. Another potential problem is over feeding treats. Again, Koi do not have the knowledge to know when to stop eating, and weight issues may come from overfeeding none nutritional foods.

The healthiest treats for Koi are what they would find naturally in their ponds, such as earthworms and tadpoles, but it will not hurt to feed Koi treats such as Lettuce, bread, fruit, and veggies. You should pay special attention to the certain foods such as corn, beans, and grapes, as they contain an outer casing, which cannot be properly digested if swallowed by Koi. If you must feed this type of foods to your Koi, be sure to completely remove the outer casings before giving it to your Koi.

Koi are none-aggressive fish. This means that they are suitable to live with other fish such as goldfish or comets. The only issue you may find is smaller, less able fish may suffer from lack of food, as Koi are quick eaters. Koi are so mellow that they have even been known to be trained to eat out of their owners hand. Koi do not have teeth, so you will not get bit if you decide to attempt to feed your Koi out of your hand.

Koi have been known to live up to 30 years under the right conditions, so if you are thinking about buying Koi, you must consider this. The record for the oldest Koi is held by a Japanese Koi, who was 233 years old when he died.


Your KOI POND After The Storm

First off, take time to breath. You pride and joys are probably fine. They may be somewhat traumatized by the whole experience, but that would be any pet caught in unusual situation. Unless extreme damage was done, their health probably is not an issue, however their home may be in need of some repairs.

English: Garden pond Česky: Zahradní jezírko

You may have been completely prepared for the storm, or the storm may have taken you by complete surprise. Whatever the case may be, you must jump into action as soon as you physically can to ensure that no further damage is done to your pond.

First, you must undo all of your storm precautions to survey the possible damage.

If you netted your pond, clear as much debris off the net as possible and remove the netting. Once you removed the netting you will be able to survey the damage and the condition that your fish are in. If high waters were expected and your sand bagged the area around you pond, as long as the water level is normal, remove all sand bags so that you can easily access your pond. Do not get discouraged if things seem out of place, and it may not be as bad as it originally looks.

Once you have removed all netting and other precautions, take time to look at the area. If any debris is present, remove it by skimming and netting. If plants or decorations are uprooted or out of place, replace them to their rightful area.

If you find major damage to your pond, it is important to remove your Koi as soon as possible. Proper bagging and transporting techniques may be needed if the damage done will take a large amount of time to fix, but there are several temporary options available if damage can be fixed quickly. You may want to consider using a children’s pool to house your Koi. If nothing is available at the time, get into contact with your local pet store or zoo, as they may have program available to help you house your Koi until maintenance can be done.

Once you have decided that only small repairs are needed, then you must focus on the water quality. You water may seem cloudy or murky due to the storm and the amount of extra water from rainfall. If the storm lasted for a long amount of time, you may be facing ammonia issues as well.

Test your water for Nitrates. If Nitrates are present, add the proper amount of salt to the water. Typically you would add 3/4 to one pound of salt per 100 gallons of water. However, if your fish are especially shocked by the situation, or seem to have sustained any type of injuries, it may be a good idea to add more. If you have plants in your pond, it may be a good idea to remove them before adding the salt into the water. Your fish should be the most important issue at this point, not your plants.

If you are having KH issues (especially if it is below 100) you will want to add baking soda to your pond. Typically you can add 1 cup of unpacked baking soda per 1000 gallons of water. This will protect your pond from a future pH crash.

Planting a koi pond is a challenge that offers great rewards. Not only will the flowers and foliage of the koi pond plants look attractive, but a diverse plant life will help to achieve a healthy balance of nature as insects, frogs and the koi fish flourish together alongside the vegetation.

You may find some plants together with your normal fish pond supplies, otherwise you will need to visit your local nursery and see what they have to offer in the way of suitable plants.

In the general scheme of things there are many plants that are suitable for koi ponds, some of which will grow in the water, some that will float, and others that will take root in the silt or mud on the floor of your pond. Suitable koi pond plants may be categorized as:

o bog or marsh plants,

o marginal plants,

o aquatic plants,
o floating plants, and
o oxygenators.
Unfortunately, many water plant species are invasive in hot climates and they are therefore considered to be invaders. So check with your local forestry or water authorities and try, wherever possible to plant whatever is indigenous to your own region.

Marsh plants
Typical marsh-loving plants thrive on moisture and they will do particularly well on the banks of an informal koi pond. Some examples include ferns, irises and lilies. See what you can find.

Marginal plants
Marginal plants normally grow in shallow water, so they do well in the shallows of a pond, or on shelves that have been created for planting.

Water-loving grasses, reeds, rushes and various sedges will all establish themselves quite easily within a koi pond, but you need to be sure they won't take over the entire area. There is a huge choice, so be selective.

There are also many leafy marginal plants, some of which will flower. These include plants like water mint, water forget-me-nots, monkey flowers, water poppies, aquatic irises and many other species.

Aquatic plants
Deep-water aquatics live with their roots submerged in the water while their leaves and flowers soar heavenward. Like floating plants, they help to keep the water cool and clear by minimizing the amount of sunlight that gets to the water, thus preventing algae from flourishing.

There are quite a few aquatic plants including the yellow fringed water lily, the impressive Japanese lotus plant and of course, the good, old faithful water lily.

Water lilies are undoubtedly one of the most beautiful aquatic plants, many of which grow on the base of the pond or in natural crevices or containers below the surface of the water, sprouting leaves and flowers above the surface. Here you just need to be aware that koi often eat from the base of the pond and so might nibble away at the roots of lilies, in which case the lilies may not survive.

Floating plants
Floating plants do have roots, but these don't need soil or silt to feed them or anchor them. Sadly some of the prettiest floating water plants are banned in the US, including water lettuce and water hyacinth with its beautiful, pale lavender flowers. Just keep reminding yourself what a nuisance these plants have become.

Oxygenators are the plants that help to maintain the balance of nature within the water itself. They are submerged beneath the surface of the water and not only provide food for koi, but also give them a really good place to spawn.

The Four Seasons of a KOI POND

Fish ponds, including koi ponds, come awake in the spring after a winter of semi-dormancy. As soon as the temperature rises above 10C (50F), your fish become more lively and your plants will begin growing again. This means that it is a great opportunity to do some upkeep - a spring clean - because you will not shock or stress your dormant fish. If you attempt it any earlier, you will upset your fish in their slumber and any later and you may disturb breeding.

English: Fish pond in winter

You ought to take out any leaves that has fallen into the pond and dredge for some of the algae. Then clean your pond filter and turn your filtration system back on, if you turned it off for the winter. Test the water for any chemical discrepancies and treat any issues.

You should also add a broad spectrum medication for common fish ailments. Depending on the medication you use, you may have to replicate this procedure a week later or when the temperature rises above a certain degree.

This is when your pond is in full swing. Your aquatic plants will be flourishing as will the algae. You must keep the algae under control, which means dredging, netting and scraping. You will have to clean your pond filter more often as well. Check it daily and keep it working at full power. The cleaner you can keep your koi pond now, the less work you will have to do afterward.

Oxygenation of the water is a major concern in the summer, because warm water is able to hold less oxygen than cold water. Therefore, you will need to keep your fountain working and your bubbler bubbling, if you have one.

If you do not have one, think about getting one. You fish and the blooming algae will be competing for the oxygen in the pond water. You can tell if the water is short of oxygen, because the fish will be gulping air at the surface.

The warm water will not only stimulate your fish and your plants, it will also bring parasites to life, so keep a keen eye on your fish' health and treat anything dubious immediately. Be on the look out for fish rubbing against the sides or each other - scratching themselves, in other words.

Feed frequently. Your fish will have eaten very little in the winter and now they have to replenish their fat for breeding and next winter.

Autumn is variable, but the first half may be like the summer and the second half more like winter. Continue to feed well. As the trees start to lose their leaves, you must eliminate them from your pond water.

Drag the leaves off at least once a day or sling a net over the pond and skim for leaves weekly. If you have any pond plants that will not survive the winter, either take them indoors or throw them away; you do not want them rotting in your pond.

Life in your pond will slow down as winter progresses. You ought to feed less often, maybe only once a day until it gets to 10C (50F) and then discontinue feeding - your fish will be in semi-hibernation at this point. Remove your filtration pumps and your fountain and switch all electrical equipment off.

Put a pond heater in the water. This is a floating apparatus that keeps a small surface area from freezing. If you allow all your pond to freeze over gases will build up, oxygen will disappear and your fish will die.

KHV- KOI Herpes Virus

KHV or Koi Herpes Virus is a potentially deadly virus which has recently shown up in the Koi industry. The first outbreak was reported and confirmed in late 1998, early 1999 in Israel. Since then, outbreaks have been reported all over the world, in  Asia, Europe, and The United States of America. As with the majority of Herpes type viruses in the world, Koi Herpes Virus is believed to remain with infected fish for their full lifespan. Even Koi that was exposed to the virus at one point or another are considered carriers, even if they did not show signs of the virus. The mortality rate for fish exposed to the virus ranges from 60 to 80 percent.

English: From USGS public information leaflet ...

When it comes down to it, any Koi is susceptible to the virus. The only real way to prevent it is to make sure that your Koi is never exposed to it. As long as you are knowledgeable about the disease, the chances of your Koi catching Koi Herpes Virus is substantially less.

Koi Herpes Virus Facts

Since the first outbreak in 1998, quite a bit has been learned about the virus. Knowing the facts about the virus may mean the difference between potentially infecting your pond, and preventing it.

Once a fish has been exposed to the virus, it will always be a carrier. Even with proper treatment, these fish will never be able to go to a new home. Sending exposed fish to a new home can potentially spread the virus to other fish. Likewise, adding new Koi into your pond could cause the new fish to get the virus, and cause a potentially higher mortality rate.
There is no known cure for Koi Herpes Virus.
Stress does not cause the disease in any way. However, stress can cause the disease to have a higher mortality rate.
74 degrees Fahrenheit activates the disease. This is extremely useful information because it allows for quarantining and testing to see whether or not fish have Koi Herpes Virus.
The virus can be spread a number of ways, including coming into contact with infected fish, water in which infected fish swam in, tools used when handling infected fish, and so on.

Preventing Further Spreading Of The Virus

Once your fish have been diagnosed with Koi Herpes Virus, the only real way to ensure that you do not infect any other fish is to consider depopulation. Depopulation is essentially the elimination of your entire population of Koi. While this might seem harsh, it is truly the only way to completely eliminate the possibility of any other fish from catching the virus.

When purchasing new fish, it is a good idea to quarantine the new fish separately from your current population for no less then 15 days. Knowing that the disease is activated at exactly 74 degrees Fahrenheit allows you to expose your fish to the right conditions for the disease to show itself. Koi that live in the conditions for this amount of time and do not develop any symptoms will have a substantially less chance of having the virus.

It is important to remember that when you quarantine your new Koi, they should remain under total isolation. This means that you should not allow anything to come into contact with the quarantined Koi, especially items that also come into contact with your current population. Separate tools, food, and water should be used, and never under any circumstances, should the tools used for your quarantined fish leave the area in which they are used. Another important thing to remember is proper hand washing procedures when handling both Koi and Koi items within the same time period.



Summer is considered one of the best and more vibrant times for your Koi pond. Temperatures are beautiful, and you are more able to enjoy your pond then during the cold Winter months. However, by no means, should your maintenance drop during the summer months. Remembering a few things during the summer months will ensure that your pond stays beautiful and lively.

Higher Temperatures Cause Less Oxygen 

During the summer months, the oxygen level in your pond actually decreases. Proper precautions should be taken, especially if you live in an area where temperatures stay high for the majority of the year. If you witness your Koi hanging out towards the top of the water, and they seem to be gasping for air, this may be a good indication that your pond does not have a high enough concentration of Oxygen.

English: Koi fish in the pond at the Gibraltar...

One way to keep oxygen moving in your water is by installing water features such as waterfalls and fountains. The more the water is moving, the more Oxygen is available to your Koi.  

If water features are not available, frequent water changes will give your fish the amount of Oxygen they need to survive. 

Watch For Evaporation

Higher heat will cause your water to evaporate at a much higher rate. Pay close attention to your water levels and do adjustments as necessary. Remember, you must remove all chlorine from the water you add. 

Summertime is Parasite Season

Not unlike other situations in life, heat brings on potential parasites and illness. The majority of parasites are not seeable by the naked eye, so instead, you must watch your Koi for signs of illness.

You may notice strange behaviors in your fish such as rubbing against objects, scratching, shaking, or shivering. Each symptom could indicate a different type of illness, so it is important to watch closely.

It is especially important to pay attention to your Koi if they start developing noticeable spots or changes on their body. They may also knock fins off. 

If any type of change is noticed, contact your local vet, pet store, or Koi dealer as soon as possible. While some parasites will cause little damage, some illnesses such as KHV or Koi Herpes Virus have a high mortality rate, and should be treated as soon as possible.

Feeding Your Koi

To remain healthy during the summer, you fish will need food high in the types of nutrients that they need. During the summer you should feed your fish a food that in low in protein at least one to three times a day. If you fish still seem hungry after feeding, you may want to increase feeding slightly.

Feeding your Koi small amounts of food at a time will prevent food from spoiling. If you feed in larger amounts, some food may remain uneaten, and it can spoil in a very short amount of time.  Fish will only eat what they need to survive, and will leave the rest. Spoiled food can cause water quality issues if close attention is not paid.

Feeding your Koi actually causes less Oxygen content in the water. During the summer this can especially be an issue, as Oxygen levels deplete in high temperatures. You can remedy this by feeding your fish in the cooler hours of the day.

Summer presents a special time to hand feed your Koi. Children are out of school, and the weather is usually perfect for being outside. Get the kids involved as they will remember it for years to come.
