I currently have a 6x2x2 180 gallon tank stocked with mainly SA and CA cichlids(still juveniles) would it wlbe worth eventually upgrading to a larger tank that's still 6 ft (can't go bigger than 6 ft) like a glasscages 6x2.5x2.5 or 6x3x2? Or is going bigger than 180 for a 6 ft tank not much of a benefit?
