Lamprologus kungweensis Shell Dweller (Lamprologus kungweensis) is a slim, reflective Tanganyikan shell dweller restricted to Kungwe Bay near Kigoma on the lake's northwestern shore — a genuinely localized species rather than one found broadly across Lake Tanganyika. It is sometimes sold under the trade name "Ocellated Shell-Dweller." In the wild it lives on soft muddy bottoms scattered with empty snail shells, where it digs pits and adopts shells as both nest and refuge.
A compact, shell-associated cichlid rather than a large rock dweller, this species reaches about 3 inches (8 cm) at most. As with all Tanganyikan shell dwellers, a soft sand substrate is essential — this species spends much of its time digging and would be injured by sharp gravel. Provide an ample supply of empty shells with round openings and open coils, clustered in groups of 3–4 with a larger rock between clusters to break direct line of sight and reduce territorial disputes between neighboring fish.
Feeding & Care Tip: An opportunistic micro-predator, this species does best on a genuine mix of meaty and dry foods — offer high-quality small cichlid pellets or flakes as the daily staple, but supplement regularly with live or frozen brine shrimp, daphnia, cyclops, and bloodworms for ideal condition and breeding readiness. Feed small portions 1–2 times daily, sized so everything is eaten within a few minutes — avoid mammalian meats like beef heart, which are not a natural or appropriate food for this species despite sometimes being suggested for other cichlids.
Use a tight-fitting lid — many shell dwellers, this species included, will dart upward sharply when startled and can jump clear of an open tank. Males are territorial and will clash if housed in tight quarters without distinct shell territories; provide ample floor space and shell clusters if keeping more than one male.
Like all Tanganyikan cichlids, hard, alkaline water is the genuine ideal here, not just a tolerated range — replicate the lake's mineral-rich chemistry with crushed coral or aragonite substrate additions if your source water runs soft. Stable water quality with low nitrates is essential; this species, like most lake cichlids, does poorly with fluctuating parameters.
| Difficulty | Easy once water chemistry is correct |
| Temperament | Peaceful with other species; territorial around its own shell/nest |
| Typical Adult Size | Up to 3 inches (8 cm) |
| Recommended Setup | 20-gallon long minimum if keeping multiple males; smaller for a single pair |
| Ideal Temp | 77–80°F (25–27°C) |
| Ideal pH | 7.8–9.0 — hard, alkaline water is the true ideal, not a tolerance |
| Ideal GH | 12–20+ dGH |
| Substrate | Soft sand essential, with multiple empty snail shells per fish |
| Primary Food | Live/frozen brine shrimp, daphnia, cyclops, bloodworms |
| Supplemental Food | High-quality small cichlid pellets or flakes |
| Origin | Kungwe Bay near Kigoma, Lake Tanganyika — a localized population, not lake-wide |
| Notes | Known jumper — tight lid essential. Cluster shells in groups of 3–4 with rocks between clusters to reduce conflict. Avoid mammalian meats like beef heart. |
