Male territoriality usually over upper surfaces of medium-sized and large rocks, small proportion of males may occupy less prominent sites and some defend areas at the base of rocks where they dig sand-scraped nests. Females, juveniles and non-territorial adult males may occur singly or form small groups (to 30 fish). Feeding aggregations with Cynotilapia afra and P. zebra in water column above rocks where they feed on plankton. Normally feeds from rock-sand substrata. |
