thanks! I thought it was velvet but maybe it's just a bad case of ick. I had to fight this trigger for 2 hours to get him out of my 240 tank, which I must say had a very bad few days after a 6 inch atlantic blue tang got very sick and eventually died, my naso 8in, sohal 7in , faxface 8in, and trigger 6 in, all got symptoms of ick. I have a small qt but I couldn't medicate all these fish so I did the whole 240 gal and everyone survived(it is fish only and base rock) thank you for your reply, I should know better than to ask a q? like medicating a tank w Live rock, but I've had it with this tank and the trigger( he's just too cool).
