Neolamprologus tetracanthus

The tetracanthus is a Cichlid which is likely to bully smaller species. It is fond of sandy areas furnished with plants - beds of Vallisneria for instance. It makes a tiny cave at the base of a rock by burrowing away the sand; the female then fixes her eggs (100-150) to the roof. Size: 1 5-18 cm.
