I have an aptasia eating file fish that together with dinos took care of them all and it was bad. While it's the ugliest fish in existence, it is also one of the most interesting. He eats out of my hand and gets along with all of the other fish. I guess I got lucky that he doesn't eat coral. I'll never have another tank without one. He's not scared of anything. He's never hiding in the rockwork. He's always scanning the rock looking for aptasia.Peppermint shrimps
