Haplochromis obesus is a species of cichlids from Lake Victoria in Africa. It is a predatory fish with a tall and strong body that hunts small animals.
Haplochromis obesus differs from related species by its thick body and large head. This fish is important for the lake because it controls the number of small species and serves as food for larger predators.
Immature form that undergoes metamorphosis before adulthood.
