MULTIFASCIATUS (Neolamprologus Multifasciatus)

A territorial fish that will defend its shell and the small territory around it vigorously. It can be combined with other species that inhabit other areas within the tank. Good tankmate choices include small rockdwellers such as Neolamprologus brichardi or smaller species of Julidochromis and open water species such as Cyprichromis. If a number of fish are kept, it will form a colony. If keeping it in this type of situation make sure there are enough shells to go around and try to buy more females than males.

This is probably the smallest known cichlid species and exhibits truly fascinating behaviour. The territories it establishes are very small, usually measuring no more than 6″ across, but they are defended vigorously. The tiny fish will even bite hands or fingers that invade their ‘personal space’! Highly recommended to anyone wishing to observe some unique behaviour on a small scale.
