Shell Dweller (Multi)

Neolamprologus multifasciatus

Cichlids - African

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.

Available Varieties

Each variety inherits the species defaults above. Only differences are highlighted.

Male (Standard)

Males are significantly larger than females. They will claim a territory containing multiple shells to attract a harem of females. They are the primary defenders of the colony's borders and are notoriously bold, sometimes even attacking the aquarist's hand.

Differs in 2 traits from base species

Also known as: Male Multi, Alpha

Adult Size5 cm
TemperamentAggressive

Female

Females are tiny, often no larger than an inch (2.5cm). They spend almost their entirely life hovering very close to or inside their chosen shell, where they rear their fry. Multiple females will live within a single male's territory.

Shell Dweller (Multi) Care Guide Summary

The Shell Dweller (Multi), scientifically known as Neolamprologus multifasciatus, belongs to the Cichlids - African family group. Adults reach a maximum size of approximately 5 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 Shell Dweller (Multi) 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 27°C, with a pH range of 7.89 and a general hardness of 1025 dGH. A moderate water flow is preferred.

The Shell Dweller (Multi) 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.

Shell Dweller (Multi) Habitat Setup

When setting up an aquarium for the Shell Dweller (Multi), 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.

Shell Dweller (Multi) Compatibility Notes

Classified as semi-aggressive, the Shell Dweller (Multi) 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, territorial behaviour may cause issues if hiding spots or floor space are limited, and their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the bottom zone can help reduce competition and territorial overlap.

Kribensis

Pelvicachromis pulcher

Cichlids - African
10 cm Semi-Aggressive

A vibrant and highly popular dwarf cichlid native to the slow-moving rivers of West Africa. Unlike Rift Lake African cichlids, they prefer soft, slightly acidic water and densely planted tanks. They are generally peaceful in a community tank but become fiercely territorial and aggressive when breeding, often digging pits in the substrate and claiming the bottom zone. They are cave spawners and require hiding spots like driftwood or coconut shells.

Dwarf Pea Puffer

Carinotetraodon travancoricus

Puffers
3 cm Aggressive

The Dwarf Pea Puffer is a tiny, fully freshwater pufferfish native to India. Despite their cute appearance, they are fierce micropredators and notorious fin-nippers. Modern husbandry standards strongly dictate they are highly social and must be kept in species-only shoals of 6 or more in heavily planted aquariums to disperse aggression and reduce stress. They require a steady diet of small snails and live/frozen foods.

Cockatoo Dwarf Cichlid

Cichlids - South American
7.5 cm Semi-Aggressive

A highly popular and vibrant dwarf cichlid native to the Amazon basin. Named for the male's flamboyant, crest-like dorsal fin. They are cave-spawners that require a fine sand substrate (which they sift through their gills) and plenty of hiding spots. While generally peaceful in community tanks, they become fiercely territorial when breeding.
