Well since only 1 tiger barb is left in the 20 long (cycling and ich), i was thinking about making it a cichlid tank. Can i get some African cichlids, I don't know the full name, but the ones that are sold in a 'african cichlid' tank, like at walmart. Could i get away with 4-5???? Also, would a bristle nose pleco be fine with them, or some ghost shrimp or some cory cat's???? Thanks
