Also known as African Blockhead. Both male and female have a pronounced fatty lump on their forehead, with the male's being significantly larger. They are blue-gray in color, and spend most all of their time on the bottom of the tank, much like a Goby.
Often they mate for life. If one of the pair dies, the surviving buffalo head will not take on a replacement.
