Plan on doing what is healthiest for the fish. I want the 180 to last 2 years but that might not happen. Right now at about 7 inches I'm feeding him every 2nd day about 1 piece of shrimp (amount he takes on one sitting). Once he gets to around 12in I'll slow down on feeding to once or twice a week. Different from piranha this guy begs for food. I hear him splashing water at the top of the tank telling me to come feed him.
