I had a Flame Angel in my first tank, he was a pretty good fish, didn't mess with any of the other fish or corals in the tank, I also had a Hippo Tang and a Fox Face, pretty good sized fish. At one point both the Fox Face and the Hippo Tang figued out that they liked the taste of my zoa collection more than the fish food I was feeding them. Soooo out of the tank they came which left the Flame Angel the biggest fish in the tank. He became a terror to all the other fish in the tank. So out of the tank he came also, he was fine as long as he wasn't the biggest in the tank.
