55g tank, minimum. I'll have the tank available soon, for $50 (stand & river-tank set-up included) Turtle is free. Just change the water 1x/month, the river kit does all the biological filtration. Cute face, really nice disposition--looks like it's smiling all the time! Eats cichlid pellets, pieces of cut-up fish, scallops, shrimp, algae wafers, etc.
