The Demanson's Cichlid "Pseudotropheus demasoni" is an extremely sharp looking African cichlid. It comes from Lake Malawi and is a more recent addition to the aquarium hobby. It was first described and brought into the hobby in 1994 by Ad Konings and was named after his good friend Laif Demason. It is also known by the common names Demasoni Cichlid and Midnight Demasoni.
This is a dwarf Mbuna that only reaches about 2 1/2 to 3 inches (6.4 to 7.6 cm) in length. It is a pretty cichlid that has a very inquisitive nature with lots of personality and spunk. It is an interesting fish to watch as it follows the contours of the rocks, swimming along at odd angles to the point of being upside down. The body pattern consists of crisp alternating stripes that are dark blue (almost black) and light blue. On the dorsal fin the stripes angle back with the lighter ones being thinner than the dark ones. The upper and lower fins, as well as the tail fin, are edge in a light blue.
