Abstract
Individual variation in body size, home range size, and reproductive s uccess among Neolamprologus mondabu (Cichlidae) females were investiga ted with reference to substrate types in the littoral zone of northern Lake Tanganyika. Larger females occupied sandy substrates and smaller ones stony substrates. Female reproductive success, estimated as the number of offspring successfully released per month, was higher on san dy substrates than on stony substrates. This may be attributable to hi gher spawning intensity and better protection of broods against predat ors in open, sandy habitats.
