After reviewing the characteristics of fish, third grade biologists learned about the cichlids that live in the hallway aquarium. Cichlids are freshwater fish from Lake Malawi in Africa. The fish like to hide in crevices and caves in their rocky habitat. African cichlids are known for their beautiful patterns and array of colors that are not typical to most freshwater fish. Males are territorial and the largest, most colorful males are the dominant fish in the tank. The females are mouth brooders. They incubate their eggs in their mouths for three weeks. They are easy to breed and we often have young fish in this tank.
