A fascinating miniature African Cichlid endemic to Lake Tanganyika, famous for making its home inside empty snail shells. Uniquely among Tanganyikan shell dwellers, the male and female Brevis will often share the exact same shell. They require hard, alkaline water, a sandy substrate (for burying their shells), and plenty of appropriately sized shells (like escargot shells) to thrive.

Brevis Shelldweller Varieties
Each variety inherits the species defaults above. Only differences are highlighted.
Male (Standard)
Males are noticeably larger than females and possess a stocky, 'bulldog' like stance. They fiercely defend the territory surrounding their chosen shell.
Differs in 1 trait from base species
Also known as: Male, Standard
Female
Females are significantly smaller than males. During threats, the female will retreat deep into the shell first, followed by the larger male plugging the entrance.

Brevis Shelldweller Care Guide Summary
The Brevis Shelldweller, scientifically known as Neolamprologus brevis, belongs to the Cichlids - African family group. Adults reach a maximum size of approximately 6 cm and have a fusiform body shape with a moderate growth rate. Classified as semi-aggressive, this species primarily occupies the bottom zone of the aquarium and produces a high level of biological waste.
To thrive, the Brevis Shelldweller requires a freshwater only aquarium with a minimum volume of 38 litres and a tank length of at least 45 cm. Water temperature should be maintained between 24°C and 28°C, with a pH range of 8–9 and a general hardness of 10–25 dGH. A moderate water flow is preferred.
The Brevis Shelldweller is a rewarding species to keep, provided its core environmental needs are met. This species is available in 2 varieties: Male (Standard) and Female. Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.
Brevis Shelldweller Habitat Setup
When setting up an aquarium for the Brevis Shelldweller, a moderate water flow best suits their natural preferences. Because this species occupies the bottom zone, the aquarium layout should prioritise sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour and shells for breeding and shelter. Keepers should note that expect substrate disturbance, so lightweight décor should be secured.
Brevis Shelldweller Compatibility Notes
Classified as semi-aggressive, the Brevis Shelldweller is a social species that requires the company of its own kind to thrive. When choosing tankmates, conspecific aggression can be intense, especially in smaller tanks and territorial behaviour may cause issues if hiding spots or floor space are limited. Selecting tankmates that favour different water layers from the bottom zone can help reduce competition and territorial overlap.

Fish Similar to Brevis Shelldweller
Pearly Ocellatus
Neolamprologus stappersi
A fascinating, tiny shell-dwelling cichlid from Lake Tanganyika. Despite their minuscule size, they possess immense attitude and will fiercely defend their chosen snail shells from much larger fish (and even the aquarist's hands). They use their mouths to move sand and bury their shells to their exact liking.
Neolamprologus Similis
Neolamprologus similis
A fascinating dwarf cichlid endemic to Lake Tanganyika. Known as a 'shell dweller' (or shellie), they live, breed, and seek refuge in empty snail shells (like Escargot or Neothauma shells). They are highly social, forming complex multi-generational colonies. They require hard, alkaline water, a sandy substrate for excavation, and at least 2-3 shells per fish.
Shell Dweller (Multi)
Neolamprologus multifasciatus
The smallest known cichlid in the world, endemic to Lake Tanganyika. They live, breed, and seek refuge in empty snail shells. They form highly entertaining, constantly digging colonies where multiple generations live together. Sand substrate and an abundance of empty shells (such as escargot shells) are strictly required for their survival and natural behavior.
Black Ocellatus
Lamprologus speciosus
The Black Ocellatus is a highly entertaining and fiercely territorial shell-dwelling cichlid from Lake Tanganyika. Despite their tiny size, they have a massive personality and will vigorously defend their chosen snail shell from fish much larger than themselves. They require a sandy substrate to bury their shells and hard, alkaline water to thrive.
Featherfin Cichlid
Cyathopharynx furcifer
A spectacular Lake Tanganyika cichlid known for its dramatic sexual dimorphism. Males display brilliant metallic hues (blues, greens, or coppers depending on collection point) and possess sweeping, elongated pelvic 'feather' fins. Males build enormous crater-like sand bowers to attract females. Because of this bower-building behavior and their high activity level, footprint (length and width) is far more critical than tank height.
Cyprichromis Leptosoma
Cyprichromis leptosoma
A unique, pelagic (open-water) schooling cichlid endemic to Lake Tanganyika. Unlike rock-dwelling African cichlids, 'Cyps' live in massive shoals in the open water column where males display to females in spectacular 3D territories. They require very hard, alkaline water and a long tank (minimum 4 feet / 120cm) to accommodate their active swimming behavior.
