I'm going to be pulling my tank out of storage soon and am thinking about putting in a Blue Acara and a Severum. What would be some safe non-cichlid tankmates for them? How about a school of barbs? Annostomus? Cory cats? Red-tail Shark? I know they'll outgrow my present tank pretty quickly, so I'll have to upgrade. Maybe 55 gal, maybe 70.
