Kliens butterfly will Eat them had one personally but once the aiptasia were gone it started on my zoanthids i have also had filefish that i never saw eat it not saying it didn't but saying i never saw it eat it. I've had peppermint Shrimp that have ate it and some that never touched it. Best in my opinion is a copper band butterfly. The one i have now Took care of all mine In less than a week. This fish is not for a beginner tho. If you do get one make sure it's eating other food and even if is eating at fish store they might not once you get them home.here's my current copper band
