I've had mine for a little over 2 years. got him at about 3" - now about 8". He's definitely the Alpha of the tank - doesn't constantly antagonize the other fish, but at feeding time he will get fairly agressive. The brunt of his agression is directed toward a one-spot Foxface about the same size as him. Everyone else pretty much has learned to stay out of his way. The only fish that doesn't put up with his "crap" is a Scopas tang - probably about 1/2 his size, but he tends to leave her alone.

Beautiful fish, but the bad reputation is deserved...
