Assuming the tank has a substrate and a few rocks and it is filled to within 1" of the top it will be holding around 14-15 gal of water. A Convict Cichlid (Amatitlania nigrofasciata) grows to about 4". Allowing for the basic rule of '1inch of fish requires 1 gallon of water' the maximum number of fish would 3. However Convicts are not gregarious fish so one of the three would undoubtedly end up being picked on and killed. Therefore I would suggest that 2 fully grown Convict Cichlids would be the maximum number one could keep successfully in a nominal 20gal tank.
