Hi Everyone, My blue eye Kole tang has this dust like light marks on its skin. I've been following this for couple of days. He's eating and behaving well. No sign of stress. Added him in the tank 5 weeks ago. I have another purple tang, 2 clown fish and 1 diamond watchman goby. There's no aggression based on my observations for past few weeks. The Kole tang likes hang inside the rock work and close to the sand bed. The tank is 3 months old and no new fish added in past 4 weeks. Not sure if it's a disease or something else. My tank does have the common hitchhiker like bristle worms, bristle starfish. Parameter:
