So, I have a gold rim powder brown who absolutely terrorizes my hippo...I will say with confidence this hippo did bring this on herself when the other tang was introduced she abused him...heres where im at, I tried to catch the brown, was unsuccessful. I was going to sump him until he got act right in his system, I will be adding more fish to my system as my bioload is low I have 6 fish i guess, 2 clowns, 1 hippo, 1 brown, 1 wrasse and a black capped basslet...I need to add bioload for sure. Size of tank 192 display, I know that would be a question, I am thinking some lyretails maybe and definitely an emporer, my melanarus wrasse nips montipora polyps i noticed...but extension is still good. My list originally consisted of sohal, Chevron....I think adding multiple fish will slow the animosity maybe I'm wrong I dunno, advice?
