Overview
This is a cool water schooling fish, peaceful and best kept in a group of eight or more. It lives in the middle of the tank and needs genuinely cool, oxygen rich water, so it suits an unheated room tank rather than a warm tropical community. Keep it only with other calm fish that share its taste for cooler conditions, and skip warm water species. Small foods suit it best: micro pellets, fine flake, and live or frozen daphnia, cyclops, and baby brine shrimp. A group is comfortable in a tank of about 54 liters with brisk, clean, gently flowing water.
In the wild
The Mount Nimba lampeye is found only in cool, clear mountain brooks on the Nimba massif, where Guinea, Ivory Coast, and Liberia meet. That upland setting keeps the water cooler than most tropical tanks, so aim for a temperature of about 20 to 24 C and soft to neutral water around pH 6.0 to 7.5. Steady flow, good oxygen, a dark substrate, and stream plants reproduce its home.
Good to know
A member of Procatopodidae, this lampeye reaches about 4.5 cm and is the type species of the genus Rhexipanchax, described by Daget in 1948. It is endemic to the Mount Nimba massif, a small mountain range that is also a UNESCO World Heritage site. Breeding is moderately difficult: it is a continuous plant spawner that lays a few eggs at a time, and the small fry need cool, clean water and tiny foods.
Did you know
Mount Nimba is a biological island: its cool streams and forests shelter animals found nowhere else, including a toad that gives birth to live young and this narrowly endemic lampeye.
