The next time you visit the Naturally Wild Swap Shop, check out our newest residents. We have received 3 critically endangered Lake Victoria cichlids (Haplochromis perrieri) from the New England Aquarium. Lake Victoria is one of the great lakes of Africa and it is the third largest lake in Africa. Several factors have contributed to the decline of this species in the wild. One of the biggest issues is the Nile Perch. Nile Perch were introduced to Lake Victoria in the 1950’s. This non-native species had a population boom in the 1980’s which coincided with the decline of Haplochromis perrieri from the lake. Sadly, the Haplochromis perrieri haven’t been seen in the wild since the 1980’s.
In general, cichlids are very popular with fish enthusiasts. There are many varieties with a huge range of colors to choose from. There are well over 1,000 cichlid species in the wild and it is estimated that there are several hundred species in Lake Victoria alone.
Cichlids are only found in tropical and subtropical zones of Africa, the Americas and Asia. In Africa, they are found mostly in the lakes of the great rift valley in east Africa – Lake Malawi, Lake Tanganyika and of course, Lake Victoria. They vary in size from the smallest at 1.4” to the largest species at 28-32” in length.
What are some of the most interesting things about cichlids? These fish can change color to reflect their mood – such as aggression, stress or being ready to spawn. They live in very different habitats including rocky shorelines, sandy or muddy bottoms or shores with and without vegetation. Most cichlids are omnivores, eating things like mosquito larvae, tiny crustaceans and worms. Some are pure carnivores and specialize in hunting smaller fish. There are also cichlids that are strictly plant or algae eaters. Some cichlid species are mouth
brooders. Mouth brooders hold eggs in their mouths to hide them from predators. Even after hatching, the babies are allowed into the parent’s mouth if they are in danger.
Our new cichlids are found I Lake Victoria over sand and mud in the littoral or shoreline zones. They can reach a total length of approximately 2.5 inches. The females are primarily gray with some black markings, while the males of the species show more color. They are hunters, eating fish for their diet. They are also mouth brooders and hold the eggs in their mouth until they hatch.
