I first encountered Cyprichromis leptosoma at a shop in Ringsted. Its unique body shape and the vibrant colors of the males immediately caught my eye, standing out from the usual cichlids. I eventually established a small group of one male and three females in my 430-liter tank.
Behavior and Lifestyle
C. leptosoma is a very peaceful species that rarely bothers other tank mates. In the wild, they live in massive schools in the open waters (pelagic zone) of Lake Malawi, feeding on zooplankton. While males may engage in minor territorial disputes, they rarely cause harm to one another. However, they are sensitive to poor water quality and stress; regular water changes and a calm environment are vital for their well-being. They should always be kept in a school of at least 5-10 individuals to display their natural social behavior.
Breeding
The male develops striking colors on the dorsal and caudal fins, especially during courtship. As open-water mouthbrooders, spawning occurs in mid-water, where the female catches the eggs before they hit the substrate. I have found the females to be quite sensitive; during an attempt to move a brooding female, she released three underdeveloped fry. Successful breeding requires a quiet environment and potentially a separate tank for the female during the later stages of mouthbrooding.
Tank Setup
As active swimmers, leptosoma requires ample space, ideally in a tank of at least 325 liters. The setup should prioritize open swimming areas in the upper and middle water layers. They readily accept most foods, including high-quality flakes and frozen foods like cyclops and brine shrimp, but a protein-rich diet is recommended to maintain their high energy levels.
