Anti-swimming cats can be mixed with other fish when they are young, such as lantern fish. Because the anti-swimming cat is relatively small at this time, and its personality is relatively mild, it will not take the initiative to conflict with other fish.

But when the anti-swimming cat grows up and becomes bigger, it is not suitable for raising it with other fish. Because its character will change, it will become more ferocious, it will also have a sense of territory, and it will actively attack other fish.
