Pseudotropheus heteropictus whose scientific name has erroneously been applied to a large species from Thumbi West Island, Metriaclima sp. "black dorsal heteropictus" â€" is seen at almost every locality around the island, and, like all kingsizei-type mbuna, favors the more sediment-free (with clear water) type of intermediate habitat. This small mbuna has been exported as 'Pseudotropheus Newsi' and achieved a degree of popularity among hobbyists under this trade name. Females are bright yellow and common in the upper 5-10 meters of the intermediate habitat.
