The tank is too small for that fish.. he will require a 55g... or he will start to have all kinda issues.... hith.. among other things.... pretty fish though
My families got massive. My family had him so long he died of old age. Ours was about 13 inches i think when it died. I remember my dad couldn't fit the fish in a bucket when it died and had to use a garbage can. I remember feeding ours beef, my dad basically trained that fish. They are very smart. I basically stuck with aggressive fish my whole life.
