Haps, for want of a better name, are basically a non-Mbuna flock that are informally called Haps because many of these fish once belonged to the broad genus Haplochromis Hilgendorf.
Most Haps are piscivores, unlike the vegetarian Mbuna. There are some exceptions to this generalisation, however, but these do well on a piscovore’s diet nonetheless. Haps are aggressive, but not as aggressive as the vegetarian Mbuna. They have long, slender, almost torpedo-like bodies, and cruise the open water. Most of these fish are silver or gray when small, and the males become very brightly colored as they mature. Females typically remain without colour.
