How big is the tank i had Malawi Cichlid a few years back i dont confess in being an expert on these things but the first thing is how big is the tank you need 50 gallons + for this sort of fish they are quite Aggressive and gets to 5-6".The jewel cichlid gets to the same sort of size and also scrappy but not to the standards of the Kenyi. Like all cichlids they need space all depends on the tank size.The Kenyi being a Malawi should have a differant water conditons they like a Ph of 8.5 and jewel like 7 but once again like Cichlids this is a wide gage.
