Butterfly koi fish are peaceful, and they are suitable for beginners. Then how to care for butterfly koi fish? Basically, it is crucial to provide sufficient space, maintain great water quality, and keep adequate oxygen. Do not worry, this segment will give you more ideas.
Water parameters & water quality
Requirements of water parameters:
- Water temperature: 65-75℉
- pH level: 7.5-7.8
- Ammonia level: 0 ppm
- Nitrite level: 0 ppm
- Nitrate level: less than 20 ppm
Butterfly koi fish are cold-water fish. Nevertheless, if the water temperature drops too low, it may cause health problems for them. On the contrary, high water temp would reduce the dissolved oxygen level. While it also improves the ammonia level, which is harmful to your fish. Also, if the butterfly koi fish are kept in a pond, a de-icer may be necessary for the winter seasons. It can avoid frozen water surfaces and enable koi to breathe.
In addition to this, maintaining great water quality is equally critical. You should change and test the water regularly, for example, once a week or once every other week. In this case, a DC water pump or a vacuum cleaner would help you out.
Butterfly koi fish are omnivorous. Nonetheless, providing a balanced diet is vital. Rich in nutrients and proteins, the pellets you feed should not be over 30 percent. Usually, you can feed your butterfly koi once or twice each day. And you should make sure that the fish can finish eating within 2 minutes. Also, it is recommended to reduce food quantities accordingly in winter. Actually, a pond fish feeder would help you a lot. It can dispense food with programmable time and portion. And the fish feeder is weatherproof and safe from wildlife.
Can butterfly koi live with regular koi?
Can you keep butterfly koi fish with regular koi fish? Generally, it is feasible to do so. Both butterfly koi and regular koi are carps, and the two are not aggressive. But there are also some differences between butterfly koi fish and regular koi fish.
- Butterfly koi fish: The older, the longer.
- Regular koi fish: Stop growing at a certain point.
- Butterfly koi fish & Regular koi fish: The former’s whiskers are slightly longer than the latter.
- Butterfly koi fish: torpedo shape
- Regular koi fish: oval shape
On the other side, what should you get to keep butterfly koi and regular koi in a fish tank? Take a 75-gallon fish tank as an example, an aquarium filter is required, because it makes sense in removing excess waste and toxic substances, such as ammonia, nitrite, and nitrate. And a fish tank filter pump can purify the green water, and create a healthy and clean living environment for koi fish. Besides that, an aquarium air pump is needed. It helps to oxygenate the water and keep sufficient oxygen.
For instance, a 10W powerful air pump is an excellent option, while the air pump also runs quietly. Moreover, adding a vacuum cleaner enables you to change the water conveniently. A vacuum cleaner helps you change water easily. It can also suck away feces and clean every corner of your tank. Furthermore, it is better to add a thermometer to check the real-time water temperature. Then, you can adjust the water temp in time.
By the way, aside from regular koi fish, pond goldfish also can be kept with butterfly koi fish. However, some fish are not suitable for butterfly koi fish tanks or ponds, such as Guppies, Danios, and Cichlids. As guppies and danios are too small, which may become food sources for butterfly koi fish. On the other hand, cichlids are aggressive. As a result, it may cause injury to butterfly koi.

Can butterfly koi live without an air pump
Without an air pump, can butterfly koi fish survive? Exactly, it depends on the fish’s density, living space, and living conditions. If the fish density is high, your fish may live only for a few hours without an air pump. Generally, butterfly koi fish can live for two days without an air pump. But koi fish would face death if they are deprived of oxygen for a long time.
As we have mentioned above, high water temp would consume more oxygen. However, a sufficient oxygen level is essential for butterfly koi fish, especially in warm weather. And it is best to keep the oxygen level at or above 6 ppm. Additionally, an air pump plays a role in oxygenating the water, expelling excess carbon dioxide, and reproducing beneficial bacteria. Hence, if necessary, you should add an air pump or air stone to aerate the water.
By the way, there are signals of oxygen depletion of butterfly koi fish:
- Fish breathe on the water’s surface
- Loss of appetite
- Fish stay at the bottom of tanks or ponds
On the other side, here are some tips about air pump usage. In general, as for tanks with low fish density, you should keep the air pump on for about 4-6 hours each day. But you should turn on your air pump for 24 hours every day if your fish tank is with high fish density and tiny space.
