Multies shell dweller

Neolamprologus multifasciatus

Wild range: Endemic to Lake Tanganyika (East African Rift); shell beds of empty Neothauma tanganyicense snails on soft sand near shore, typically in moderately deep shoreline water (FishBase, Seriously Fish, Aquarium Co-Op). (Africa)

Husbandry parameters

Difficulty: beginner
Adult size: 2.50–5.00 cm
Min tank: 10.0 gal / 40.0 L
Temperature: 24.0–27.0°C
pH: 7.5–9.0
GH: 8.0–25.0 dGH
Flow: gentle
Water: freshwater
Temperament: semi-aggressive
Diet: carnivore
Swimming: bottom
Schooling: No
Min group: 6
Community: No
Nano: Yes
Reproduction: Obligate shell-brooder / colonial shell-dweller. Start with ≥6 juveniles (ideally more females than males) and provide ≥3 empty snail/escargot shells per fish over deep sand (Seriously Fish, Aquarium Co-Op, Practical Fishkeeping). Female entices a male to her chosen shell, lays eggs inside; male fertilizes at the entrance (or enters if shell is large enough) then is excluded. Eggs hatch ~24 h; fry free-swim ~6–7 days and remain near the shell entrance until the female eventually evicts them. Colony raises multiple generations together; cull/rehome as the population expands. Breeding easiest at ~25–26.5°C, pH ~8.0–8.5.
Biotope: Lake Tanganyika shell beds
Countries: Democratic Republic of the Congo, Tanzania, Burundi, Zambia
IUCN: Least Concern

Natural habitat

Soft sandy substrates where empty Neothauma snail shells accumulate; each fish claims a shell and a tiny territory (~15 cm across). Congregates in large colonies but lives as pairs/harems in very small defended shell territories; feeds on plankton drifting above the colony (FishBase, Seriously Fish).

Where they are found

Catalog primary locked as Neolamprologus multifasciatus (Boulenger, 1906) per trade/ITIS/FishBase/CoF current status (ITIS TSN 648810 Current Standing valid; CoF Current status Valid as Neolamprologus multifasciatus (Boulenger 1906), spid ~38111 / originally Lamprologus multifasciatus Boulenger 1906, type locality Niamkolo Bay, Zambia, Lake Tanganyika; FishBase accepted Neolamprologus multifasciatus (Boulenger, 1906)). Konings (2015, 2019) treats as Lamprologus multifasciatus — kept as synonym/alias only (naming rule: trade/ITIS primary). Older combination: Lamprologus multifasciatus Boulenger 1906. Trade names: Multies / Multis / Multi shell dweller, Multifasciatus shell dweller, dwarf shell dweller. LFS caution: commonly confused with Neolamprologus similis (stripes continue onto the head/to the eyes in similis; stop behind the gill cover in multifasciatus — Aquarium Co-Op). Also sold generically as 'shell dwellers' alongside Lamprologus ocellatus and Neolamprologus brevis (distinct species). IUCN Least Concern (Bigirimana 2006; Wikipedia / IUCN Red List T60602).

Aquarium care

Beginner-friendly Tanganyikan shell-dweller and one of the smallest cichlids in the hobby. Locked care band: 24–27°C, pH 7.5–9.0, GH 8–25 dGH, adult ~2.5–5 cm (females smaller; males to ~4.5–5 cm), minimum ~10 US gal / 40 L for a starter pair/small group with a larger footprint preferred for a growing colony (Seriously Fish 24–27°C / 7.5–9.0 / 8–25 / 40 L pair; Aquarium Co-Op 24–27°C / 7.5–9.0 / ≥8 GH / Multis OK from 10 gal, prefer 20-long; Practical Fishkeeping 24–26°C / 7.8–9.0 / 15–25°H / 45 cm footprint for a couple of pairs; FishBase wild 24–26°C, pH from 8.0, dH 15–25). Soft sand ≥5 cm deep for digging; smother the floor with escargot/Neothauma-type shells (≥3 per fish). Hard alkaline water is mandatory — soft acidic tap is a poor match without remineralizing. Sponge filter or prefilter on intakes (tiny fry). Beginner difficulty; colony expands quickly so plan rehoming.

Feeding

Mostly carnivorous zooplankton feeder in nature (FishBase, Aquarium Co-Op). In aquaria: crushed flakes, nano/small cichlid pellets, live/frozen baby brine shrimp, Cyclops, Daphnia, microworms, and occasional bloodworms (Seriously Fish, Aquarium Co-Op, Practical Fishkeeping). Fry stay near shell mouths waiting for tiny sinking foods — target-feed the shell openings. Adults will rise for food.

Compatibility

Semi-aggressive / territorial around shells but tiny — best as a species colony or with carefully chosen Tanganyikan open-water or rock-zone mates that leave the shell bed alone (Seriously Fish, Aquarium Co-Op, Practical Fishkeeping). Good larger-tank companions: Cyprichromis, Neolamprologus brichardi, smaller Julidochromis with a clear rock zone separated from the shell field. Avoid other bottom-dwellers that contest shells. Not a general community fish with soft-water tetras/corys. Not confused with / do not mix casually with N. similis, L. ocellatus, or N. brevis without planning space.

Breeding

Among the easiest Tanganyikan cichlids to breed once shells, sand, hard alkaline water, and a mixed-sex group are provided (Seriously Fish, Aquarium Co-Op, Practical Fishkeeping). Female displays at her shell entrance; eggs deposited inside; male fertilizes at the rim; female fans/guards. Hatch ~24 h; free-swim ~6–7 days; mother eventually evicts juveniles. Multi-generational colonies are the norm. PVC elbow+end-cap 'shells' help commercial breeders bag fish. Cull or expand tank as numbers climb.
