Multi Shell Dweller
Neolamprologus multifasciatus
Animalia›Chordata›Actinopterygii›Cichliformes›Cichlidae
📍 Lake Tanganyika, Africa
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.
Tank Mates
Provides empty shells for dwellers to use; peaceful and won't compete for resources
Creates shells naturally and shares bottom habitat without aggression
Small, peaceful bottom-dweller that won't compete for shells or food
Small, mid-water swimmer that avoids shell-dwelling cichlids; similar water parameters
May be predated upon by larger shell dwellers; only suitable in heavily planted tanks with plenty of cover
Common Diseases
Ich (White Spot Disease)
White spots on body and fins, rapid breathing, rubbing against objects
Raise temperature to 28-29°C, perform daily 25% water changes, use ich-specific medication if needed; maintain excellent water quality
Bacterial Infections
Torn fins, cloudy eyes, lesions on body, lethargy
Improve water quality immediately, perform frequent partial water changes, consider antibacterial medication if severe
Malawi Bloat
Abdominal swelling, loss of appetite, difficulty swimming
Improve water quality, feed high-quality varied diet, avoid overfeeding; may indicate poor water conditions or nutritional deficiency
Fin Rot
Frayed or deteriorating fins, discoloration at fin edges
Perform frequent water changes, maintain pristine water quality, use salt baths or antibacterial treatment if severe
