I'm curious, can these two different lakes of cichlid fish live together in a tank? I was at the pet store and asked what cichlids could go together in this tank (besides just housing Tanganyika) and the guy in the aquarium area said it might be possible to house Malawi with them. Is this really possible? I'd like to get more fish tomorrow if I can, I've ordered a book on the Tankanyika fish but am looking online tonight for more too.
