I am currently quarentining a 3spot damsel, 2 percula's, and a yellow tang. After two weeks in the qt the clowns and tang are doing great, but my damsel just turned for the worst. He is breathing heavily and looks to be loosing his color. He shows no sign of ick anymore, but what could it be? I was planning on taking him back to the lfs after treatment, but I still dont want him to die. Can anyone help me save this guy?
