Found in the Congo River system, Orthochromis stormsi is a goby type cichlid from West Africa. It has a small swim bladder and spends most of its life along the bottom of shallow, slow moving waters near the shore. O. stormsi males can reach almost 5" with females being about an inch shorter. Believed to be a herbivore in the wild, they do well with a spirulina based food in captivity. There can be some aggression between males, but for the most part O. stormsi isn't known as an aggressive fish.
