The Pseudotropheus Ice Blue has the typical torpedo shaped zebra body. The males are more colorful than the females. Males have an overall ice blue color with very faded vertical bars on the body. The dorsal fin and the top half of the tail fin are orange and there are several egg spots on their anal fin. This coloring makes them easy to identify. Females are a drab color of brown-gray, with slightly more obvious vertical bars. Sometimes the females can be a pink coloring with a hint of the blue on their sides. Most Mbunas can live up to around 10 years.



The Pseudotropheus Ice Blue is an omnivore that can be fed a good quality cichlid pellet or flake. They can occasionally be given krill or artemia, but no mammal meat as this can eventually cause intestinal distress and death.



The Pseudotropheus Ice Blue has been bred in captivity. Obtain six to eight young fry and once mature, feed two times a day to condition them to breed. If they will not spawn, then that usually means there is a very aggressive fish in the tank. Removing that aggressive fish will prompt a more relaxed atmosphere and encourage spawning.


Compatible with

It can be kept in a tank with similarly tempered Mbunas. Do not house with fish of the same color and shape though, as the male will look at them as trespassers and attack them. It will quickly adapt to prepared foods and is readily bred if not kept with overly aggressive tank mates.



The Pseudotropheus Ice Blue is only moderately aggressive compared to other Mbuna, but is still not a community tank specimen with fish other than cichlids.
