DietOpportunistic carnivore; feeds on small invertebrates, crustaceans, and prey sifted from the substrate; non-territorial schools are known to raid other fish territories in a swarm ('the mob'), consuming whatever invertebrates are exposed.
BreedingSubstrate spawner — female spawns inside an empty Neothauma snail shell; male fertilizes from outside by pressing his vent to the shell mouthClutch laid egg by egg over approximately 6–12 hours; female broods inside the shell for ~10–14 days
Sexual dimorphismYesExtreme sexual size dimorphism: males reach 13–15 cm TL, females only ~4–4.5 cm TL. Body-mass ratios of 12:1 (Wonzye Point, Zambia) to ~60:1 (Muzimo, northern DRC) have been recorded — the most extreme male-larger dimorphism documented in any animal. A third 'dwarf' male morph, genetically fixed via Y-linked inheritance, is smaller even than females.

Lamprologus callipterus "Cape Mpimbwe" is the Cape Mpimbwe population of Lamprologus callipterus, a geographic colour form from the Tanzania coast of Lake Tanganyika in the north-central part of the lake. It is the same species as Lamprologus callipterus, distinguished by its collection locality and local coloration; aquarists keep and breed it as a discrete, provenance-labelled line.
