Wellll he's already been in there for 2 months and he hasn't grown that much and they get, carnivore pelets of some sort, usually hikari, bloodworms and goldfish that get fed a color enhancing flake so they have spirulina and crap like that in them, AND theres only 4 fish in there, they're not overfed, and the water is clean..... And there have been previous ones in that SAME tank that took a couple of years just to get a foot and a halfish so?
