Sick ornate wrasse

[bromion]

My ornate (christmas) wrasse is not doing well. He has always been a hider, coming out when the other fish are done eating, but recently he stopped coming out altogether. The other day I saw him hiding in the sand and saw my opportunity to get him into quarantine. The biggest physical problem appears to be a bit out of his dorsal fin. A big bite. He is also not eating, far as I can tell. Also, his eyes are cloudy, which I am not sure is normal or not, since I didn't usually get a good look at them.

Any ideas on treatment? I am trying hyposalinity for now. Lowering it slowly. Other ideas?
