The filefish has been a great addition to my 55-gallon tank. It actively eats Aiptasia anemones without harming other fish. I feed it a mix of mysis shrimp and frozen algae daily. It’s shy but stays active in the tank.

I noticed it nibbles on a few soft corals at first, so I rearranged the tank layout. Since then, it’s been focused on eating Aiptasia. Feeding it shrimp and krill works well.
