I have a 55g set up, it's current inhabitants are 2 red eared sliders, and a 21" clown knife (he came w/the tank). Once the sea monster is rehomed, I'd like to put 1 or 2 of either bluegill, or sunfish in this tank. Aside from the turtle fodder, they'd be the only fish. Eventually, the 2nd slider will get his own tank, so it'd be just 1 turtle and the 1-2 fish. Would the 55 be large enough for a 2 of either species, or should I stick to 1?
