My Bi-Color Dotty is a Terrorist -Please Help

[Jfarooqpak]

Hi my BiColor Dotty is acting like a complete terror in the tank which is a 32 G Biocube. Over night it has butchered the Yellow Tang’s Fins. I taped of a bigger Dotty’s pic on one side that hasnt helped. It was fighting with thr cleaner shrimp before this and the only other inhabitant of the tank which is a PJ Cardinal. Please help before the poor Yellow Tang Dies. Thank you.

The best (only?) solution is to rehome the little terrorist. I put the one I had many years ago in with my 4' moray eel after he had killed off pretty much everything else in the tank.

Never again.
