No, not keeping it with anything at all right now. A complete 55gal all for itself. Kinda funny since its only 2.5". This little bugger is an AGGRESSIVE punk though!! Chases my finger around the glass, always front and center wanting more food. Geez. I am a little worried to do a water change. Totally tore up a couple of feeder gold fish, so I think this is definately a solo fish. ha
