1. How big a fish tank will koi fish have? At least 1 m fish tank should be used to raise koi fish. This kind of fish in koi fish is relatively large, belonging to large ornamental fish, which has certain requirements for space. Moreover, it consumes a lot of oxygen, so it needs to be kept oxygenated to prevent fish from floating due to lack of oxygen. In the daily feeding process, there are many foods to choose from, but it is best to choose animal feed so that fish can grow fast.
Second, what are the disadvantages of keeping koi fish in a small fish tank? 1, affecting development: The biggest problem of raising koi fish in a small fish tank is affecting development. Because this kind of fish in koi fish can grow to more than 1 m, a too small fish tank will limit its body growth, resulting in it not growing to a suitable length. Fish that don't grow up look ugly, and even become old fish after a long time.
2, can't move: Because the fish tank is relatively small, koi fish can't move normally. If you don't swim for a long time, it will make the fish fat and even reduce the resistance. Moreover, if the fish can only be suspended in the fish tank, it seems that there is no spirit, and the overall ornamental value will be greatly reduced.
3, easy to get sick: the fish tank is too small, and there is less water. This makes it difficult to maintain the water quality. Once the water quality deteriorates, koi fish will get sick. But raising fish in big fish tanks will not have such troubles, the water quality can be maintained for a long time, and the fish can grow healthily.
