Multi Shell Dweller

Neolamprologus multifasciatus

AnimaliaChordataActinopterygiiCichliformesCichlidae

📍 Lake Tanganyika, Africa

Ask Finn

The smallest cichlid in the world, barely reaching one inch. Lives in colonies inside empty snail shells that it actively excavates and rearranges. Fascinating colony behaviour in a dedicated nano shell-dweller tank.

Care Guide

Diet

Multi shell dwellers are carnivorous and require high-protein micro foods including crushed flakes, micro pellets, and small frozen foods like brine shrimp and daphnia. Feed small amounts once daily, as their tiny mouths require appropriately sized particles. Supplement occasionally with quality cichlid pellets crushed to fine powder.

Behavior

These are the world's smallest cichlids and exhibit fascinating colony behavior, living communally in empty snail shells which they actively excavate and rearrange. They are semi-aggressive toward each other but establish hierarchies within colonies; males are territorial over shells while females are more social. They spend most time at the tank bottom, constantly working shells and displaying intricate social interactions.

Breeding

Breeding in captivity is moderately difficult but achievable in dedicated shell-dweller setups. Pairs will spawn inside shells, with females guarding eggs while males defend territory; provide multiple shells per fish to reduce aggression. Fry are tiny and require infusoria or liquid fry food initially, making large-scale breeding challenging for beginners.

Torn fins, cloudy eyes, lesions on body, lethargy

Treatment

Improve water quality immediately, perform frequent partial water changes, consider antibacterial medication if severe
