The females will also have a lighter belly than the males and shorter pelvic fins Breeding Melanochromis cyaneorhabdos are maternal mouth brooders. When the eggs have been laid and fertilised, the female will hold them in her mouth for 21 days incubation. During this time she will hide away and when the fry are released they can be fed on crushed flake and newly hatched brine shrimp. Lifespan The expected life span for Melanochromis cyaneorhabdos is 10 years. Short description Supply plenty of hiding places in the tank by using rock work. It is best to keep 1 male with 2-3 females but keep your eyes out for a single female being harassed by the male. Pictures Bought by aqua-fish.net from jjphoto.dk.
