I agree 75gal with mass filtration. Preferably two canisters.
They're messy fish. I'm keeping two currently in a 72 bow front with fx5 and a fluval 405. Healthy and plenty of turning space. Both reaching 9" within the last 8+ months I've had them. Never hith and free of diseases. No other tank mates though.
