my tanks size is 40 gallons and it is an african cichlid tank with yellow lab. 3 chinuni, and three unidentified (juviniles). From the info i looked at they need a max tank size of 35 gallons and shouldn't be kept in groups as they can become agressive with eachother. But from what you are saying i don't see them doing to well in an african tank.... am i right in assuming this?
