I just got a general question for you guys. I have a Clown Trigger Fish and i just wanted to know why he changes colors soo often (camouflage) i mean he does it a lot i heard from 1 source that it was a form or a sign of stress. Then i heard from another person that he's just plane old camouflaging nothing to get worried about. Either way why do they camouflage i mean for what reasons? And is it something i should look into or be worried about? His habits didn't change he seems healthy as a horse.
