F. Witte. From form to fishery: an ecological and taxonomical contribution to morphology and fishery of Lake Victoria cichlids. Anonymous. Anonymous. 1984. In its natural habitat adult Haplochromis squamipinnis (a species endemic to lakes George and Edward) is a piscivorous predator.However,in tanks it easily survives on all kinds of food.The premaxille of specimens in the following aspects:1) shorter lenght of the ascending arm,2) larger angle between ascending and dentigerous arm,3) a symphyseal articulation facet is genaerally present. |

The changes are epigenetic and probably related to the way of feeding.Comparison of premaxille of wild-and tank-specimens increase the biting force.This is probably related with frequent sand-digging for food.The implications of such epigenetic changes for taxonomy and morphology are discussed.
