Who Gives A Fish Forums

just got a rio 400, 450 litres, still got all my old mbunas - afra haras, acei, chailosi, saulosi, auratus and labs. been wanting a cryptocara moorii for ages, saw one when i had my rio 240 but was told the tank was too small and they need to be in groups. my new tank's 60x20x26 inches, is that big enough? could i get away with just one moorii if i add a few other haps to the mix?
