Scientists at the Georgia Institute of Technology have found that by applying chemicals to manipulate genes in a developing embryo, they've been able to change the brain of one type of cichlid fish to resemble that of another.

Biologists have genetically mapped the sex chromosomes of several species of cichlid fish from Lake Malawi, East Africa, and identified a mechanism by which new sex chromosomes may evolve.

Most fish rely primarily on their vision to find prey to feed upon, but a University of Rhode Island biologist and her colleagues have demonstrated that a group of African cichlids feeds by using its lateral line sensory system to detect minute vibrations made by prey hidden in the sediments.
