Right now he's in my 20 gallon with a King Tiger Pleco, a Butterfly Pleco, 4 rainbowfish, 2 killiefish and 1 blue gourami. I know that tank is waaay to small for him, trust me I am upgrading before very long. (getting plans ready for "his" tank..lol How big would you all suggest, would 75 gallons be ok or 100?
