This Carpenter's Wrasse has been in my QT since April 9 with a couple of Ochre Striped Cardinals. I started hyposalinity treatment on the group and they've been at 1.009 sg since April 16. About a week into hyposalinity, the wrasse broke out in what I thought was ich. He had the white grains mostly around his head and on some of his fins. He was in bad shape for a couple days, spending most of his time lying in hiding spots looking dead, but jumped up to eat when I fed the tank. He seemed to recover somewhat and be back to swimming in the water column regularly, but for the last two days he looks right dead and has this white stuff on his dorsal fin and a bit around his head. He is still breathing and his eye moves to track me. Every once in awhile the current will roll him on his back and he will right himself again.
I would have thought that ich should have cleared out of his system by now given that he has been in hypo for 17 days now. Am I dealing with something else here? Might this be velvet? The two cardinals in the same tank haven't exhibited symptoms of anything yet. I know that hypo won't kill velvet though, just slow it down.
