Altolamprologus compressiceps is a distinctive and highly specialized cichlid species endemic to Lake Tanganyika. Known for its unique body shape and predatory behavior, this fish is a favorite among keepers of Tanganyikan aquariums.

Its most notable feature is its extremely laterally compressed body, which allows it to slip between narrow rock crevices in search of prey. The head is large and angular, with strong jaws adapted for ambush hunting. Coloration varies by locality but often includes earthy tones, vertical barring, and subtle metallic highlights, giving it a refined, stealthy appearance.

A. compressiceps lives among rocky habitats where it stalks small fish and invertebrates. In aquariums, it thrives in setups with abundant rock structures, caves, and hiding spots. Although generally calm, it is a slow-moving but effective predator, and tankmates should be chosen carefully to avoid small fish being eaten.

This species is best kept in stable, high-quality water typical of Lake Tanganyika, with a carnivorous diet consisting of protein-rich foods.

Graceful, intelligent, and evolutionarily unique, Altolamprologus compressiceps stands out as one of the most fascinating ambush predators in the cichlid world—perfect for hobbyists who appreciate behavioral complexity and natural elegance.
