The species is most commonly associated with areas containing
large numbers of empty snail shells. It usually inhabits such shell
beds, but it can also be found in habitats without snail shells,
where it always lives close to rocks and at greater depths
(deeper than 25 m). In shell-rich habitats, it may also occur in
shallower water, at depths of around 10 m. Regardless of habitat
type, it always lives in colonies.
Geographic distribution:
Occurs in the southern part of Lake Tanganyika. The distribution
extends south of Kapampa along the Congolese shoreline, continues
along the entire Zambian coast, and further along the Tanzanian
shoreline southwards to Kala.
Typical adult size:
The smallest known Tanganyikan cichlid. Males reach up to
approximately 5 cm total length, while females are rarely larger
than 3.5 cm. Individuals living near rocks rather than in shell
beds may grow slightly larger, with females reaching up to about
4 cm.
Sexual dimorphism:
Apart from size differences, males and females are visually
indistinguishable.
Recommended aquarium size:
60 liters.
Aquarium setup:
The aquarium should have a thick layer of fine sand, as these
fish actively dig and move substrate. A large number of snail
shells should be provided, ideally at least one per individual,
which are used for shelter, breeding, and territory defense.
Shells of Tanganyikan snails such as Neothauma are ideal,
but suitably sized local snail shells can also be used.
Although the species can be kept with other Tanganyikan cichlids
that are not large enough to prey on them, it is strongly
recommended to keep it in a species-only aquarium. In such a
setup, the natural expansion and social dynamics of the colony
can be fully observed. In community aquaria, other cichlids will
usually restrict the colony to a limited area.
Diet:
Carnivorous. In the wild, it mainly feeds on planktonic
copepods drifting past the shells, as well as small invertebrates
found around the shell beds. Rock-dwelling colonies feed in a
similar way. In aquarium conditions, it readily accepts most
foods, provided that the food particles are small enough for
its tiny mouth.
Breeding:
Forms breeding colonies typically consisting of two to three
males and four to five females, each individual occupying its own
shell. It is best to start with a group of at least six juveniles
in aquarium conditions to allow natural pair or harem formation.
Spawning takes place inside the female’s shell and is rarely
observed directly. The first visible sign of breeding is usually
the appearance of fry inside or near the shell.
Clutches are small, typically consisting of about 10–15 fry,
which is proportional to the small size of the female. Fry should
be fed newly hatched Artemia several times per day once
they are observed. Juveniles gradually occupy empty shells nearby
and help expand the colony. Multiple generations often coexist,
with older juveniles tolerating and helping to protect younger
fry.
Aggression:
Generally peaceful cichlids, but despite their small size they
vigorously defend their own shell and immediate territory.
Special notes:
One of the most commonly kept Tanganyikan cichlids in the hobby,
largely due to its very small size and suitability for small
aquaria. It closely resembles Neolamprologus similis.
The most reliable external difference is that the vertical bars
of N. multifasciatus do not extend onto the head, whereas
N. similis shows two bars on the head.
DNA analyses indicate that these two species are very closely
related and that N. multifasciatus may have originated
through hybridization. It is suggested that N. similis
represents the older lineage, having been present in the lake
during periods of lower water levels, while N. multifasciatus
may have arisen later after recolonization of the southern basin.
Neolamprologus similis occupies the central part of the
lake, between Cape Tembwe and Kapampa on the Congolese coast, and
between Cape Kabogo and Ikola on the Tanzanian coast, whereas
N. multifasciatus is restricted to the southern basin.
