Depends on the size of the fishes, as C. moorii grow very slowly. Back in the day I had a group of about 10 individuals in a 6-foot, 150 gallon tank. This included 2 co-dominant males and 8 or so other fishes of indeterminate sex. These fishes were not full grown, the largest being about 6 inches or so, if memory serves. It's hard to extrapolate this to a 4-foot tank; my guess would be one male and a few females. Perhaps others have more relevant experience?
