Description: Lamprologus congoensis is well adapted to its life in rapids with its streamlined body, strong pectoral fins, large tail fin and reduced swim bladder.
The males grow significantly larger, have numerous golden iridescent scales on their sides of the body and develop a frontal hump with age.
For breeding use water temperatures between 25 and 27 °C. The polygamous male spawns in turn with the females. These all occupy different caves, limiting their territories among themselves. Pairing courtship and aggression constantly alternate. The females try to lure the male into their cave. The eggs are almost 2 mm long and are usually placed on the ceiling of the cave or on a wall. The eggs adhere on their side; each spawn has up to 80 eggs. The larvae hatch after 54 hours at 26 °C and are spit into a pile on the floor of the cave by the brooding female. After an additional 8 days, the young are free-swimming. The female guards the spawning cave with the young while the male controls the entire harem area.
