Found throughout Lake Malawi, Otopharynx argyrosoma spends its days in the sandy-bottomed shallows. O. argyrosoma sifts through the sand in order to feed on small crustaceans and other invertebrates. Males will build bowers to attract females and define their territories. Over-fishing with trawl nets has reduced populations in certain parts of the lake.

Not common in the hobby, but available from time to time. Often going by the names Haplochromis eucinostomus and H. longimanus. There is also some confusion with other species. However, Otopharynx argyrosoma has red spots on its flank. Males can reach over 6″ in length. Aquariums should be appropriately sized and have sandy bottoms. A diet high in protein is recommended.
