My tang has been in QT for about 2 weeks now. I noticed some discoloration on his sides. It doesnt appear to be ich as the spots are kinda like lines. But im new to this and could just be wrong. He's eating fine and no other signs of anything. The 2 clowns in there with him dont have any sign of anything either. Sorry for the bad photo, hes very shy and ran away any time he saw my phone.
