I had a new purple tang in QT (and the tank was way too small). So I started up a new one and put him in there (20g L). What prompted me is I saw what looks to be HLLE on his face. When I got him in the new tank I noticed the lateral line a bit more. I'm going to keep him in the larger tank, but, is this permanent or do you think he'll outgrow it?
