I have an aiptasia eating file fish that does eat aiptasia but he also snacked on some acans (they recovered). I would like $20. He will definitely eat your aiptasia as my tank was covered. I'm hoping that now he's taken care of the visible stuff the peppermint shrimp can keep it under control. He is a cool fish and I would keep him if he didn't try and eat my acans. Local only.
