Above: Stigmatochromis modestus, a small individual with the characteristic "modest" dark brown coloration. The red lappets (tips) of the dorsal fin membrane between the spines are also distinctive.

Notice the black spots on the body and fins; sometimes called "black spot disease," these spots are the metacercarial cysts of parasitic trematode worms. These are not harmful to the fish. In the wild, the parasites began in a snail, then settled on the fish, and would be able to complete their life cycle only if the fish were eaten by a bird, such as a kingfisher or fish eagle, which the adult parasite requires. In an aquarium, its life cycle cannot be completed.
