Powder Brown

[JimD]

Ok, soI have this beautifull Powder brown tang and lately Ive noticed his tail fin wasnt as perfectly formed as it usualy is. Looks like someone has been chewing on it, now to the point to where the poor guy basicly has no tail. The only other fish in the tank are two true Percs and a medium Foxface. Could the Foxface be the culprit? No room for a hospital tank so I may need to depend on someone here local to nurse him back to health while I decide what to do.
Thanks....

Have you seen the foxface picking on it? How long have they been together? Also, a successful method for territorial/aggressive fish is turning your lights off for a day and rearranging your rockwork a bit so as to throw the aggressive fish off a bit

I am not sure how things work for saltwater aggression, but my cichlids get all of there rocks rearranged every 6 months or so. that keeps them from killing ech other.

The powder brown has been with the Percs and the Foxface for about six months. I havent seen anything like this until the other day. Im wondering if hes getting harrassed during the night by some unknown resident, everyone else looks fine.
