If you have a set, you can keep small fish, but turtles bite fish, especially small fish. This is a delicious pig nose meal. I suggest you don't have a set. Let's raise a dragon fish. Arowana is suitable for clean feeding. Very domineering. Just don't wear a pig's nose. It's too big to spoil the fun. If you keep too many fish, your head will hurt. Believe me, I will raise too many. Very headache.
