Blenny used to be fat and competed with clowns for flakes and shrimp. Runs up when fed, takes a bite or 2 and then hides. Doesn't seem to be afraid of clowns. Very thin. Have had in same tank for over 2 years with same fish. No new fish have been added since setup. Did stop feeding flake food because read durties tank faster. Feeding flakes and some nori last few days, but still same behavior. Hope he will survive! Was so cute and a character! Zoa like looking coral is taking over rock though. What's going on?
