The phenomenon of the anti-swimming cat fish biting fish has a relatively large relationship with its size. When it is small, its character is relatively mild, and it will not attack other small fish in general.
But when it grows up and its size becomes larger, its character will also change and become more ferocious. Moreover, it will grow up to have a stronger sense of territory. Therefore, when it feels that other small fish violate or threaten its territory, it will take the initiative to attack, at this time it is easy to bite the fish. In more serious cases, they will even eat some small fish.
When the anti-swimming catfish is relatively young, it can be mixed with other fish, because at this time the anti-swimming cat fish is relatively small, and its personality is relatively mild, and it will not take the initiative to conflict with other fish. But when it grows up and gets bigger, it's not very suitable to be raised with other fish. Because its character will change, will become more ferocious, will also produce territorial awareness, will take the initiative to attack other fish. Therefore, when it grows up, it is generally not recommended to carry out polyculture. If you have to mix, you can mix some fish about the same size as it.
