Noticed my 1 month old kole tang was infested with ich, when I bought him he was picking on a dead fish in tank. Never thought anything of it, he also picked at the glass/rocks and wouldn't eat seaweed/pellets/flake/clip. He chased himself in the reflection it seemed., he was the worst and Flame Angel was struggling too, rip you 2. My 2 clowns have slight case bit are happy and swimming still, what are my options? Thought about picking up a 10g QT
