Got a new purple torch with yellow tips and added with my green torch to make a garden. I woke up this morning to find them shredded because all the sudden my hippo tang is biting the tentacles off!!! Just being a butthead any one elsee just have a rouge hippotang randomly start being aggressive and start destroying coral? HELP he eats like a pig to by the way....they get NORI often too and he isn't skinny....he is fat!
