I found ick on my powder brown tang. Setup a small tank and got my two clowns out of the main display and tried to catch the tang. have been trying to catch the tang for about 10 days. Came home from work today and the tang had spots all over him and was breathing heavy and moving really slow. I finally was able to catch him and get him in the hospital tank for treatment. Am i too late in treating him or can he pull threw.
