Lionfish can be mixed with other fish, as long as they are not with carnivorous fish. Lionfish are easy to raise, and the feeding methods are the same as other goldfish, but remember that lionfish cannot be mixed with small fish.

If both are male, don't Keep them together. The males of lionfish are very territorial. If they are put together, they will fight to death due to territorial disputes. If they are a male and a female, they can be raised together.
