we had a panther grouper and I thought we kept him well fed, he got along with the other until one day he feasted on everything that would fit in his mouth (he ate 2 clownfish, 4 firefish, 1 scooter blenny, 1 neon goby) needless to say that he then went to the fish store for a credit on my account, he was fun to watch and had alot of personality, but I could not afford his healthy diet.
