We purchased a Minibow 2.5 galleon tank for our betta. I wanted it to be big enough that our brat of a bengal cross kitten couldn't tip it over or push it off the dresser. Stick (the fish) really seems to like it. It has a filter in it also so we really only change the water about once a month. As for food we feed him one that is like pellets and says it is color enhancing. He seems to like it also.
