If you're gonna pay $100, might as well try to find a bigger tank for same price. I got a 29 gallon fully loaded at yard sale for $3 and one off craiglist, tho sold as a 55 gallon, for $30 with stand. Plus those fish if I'm not mistaken get at least 5 inches. Dolphin cichlid, if thats a Hap. Moorii then its gets 8 inches and will need a bigger tank.
