About this image

Illustrative or adapted specimen presentation. It is not a documentary photograph of LIMNIC stock, a voucher specimen or evidence of successful breeding.

Scientific references establish the profile’s research context; they do not by themselves establish image ownership or validate the depicted animal.

Retained credit record — asset match and permission not yet verified: von Rintelen & Cai (2009), Fig. 25 · CC BY 4.0; adapted presentation.

Media provenance register · Original creator and reuse permissions remain subject to verification where the retained record is incomplete.

Identity and origin

Origin
Malili lake system, including Lakes Masapi and Lontoa, Sulawesi, Indonesia
Identity
Described freshwater species; lake/catchment endemic

A variable yellowish, brownish or translucent species, sometimes banded. It occurs in both lake and river habitats; the name does not restrict its distribution to Lake Masapi alone.

Habitat and care

Mixed substrates, often plants and leaf litter. A published morphology plate is shown instead of an invented live photograph. Habitat and identity reference

Use a mature, species-dedicated system with stable water chemistry, strong oxygenation and suitable grazing surfaces. Follow documented breeder parameters for the exact species and colony; do not transfer a soft-water bee-shrimp recipe to an ancient-lake species.

Plan before choosing

Habitat
Lakes and connecting waters
Size and measurement
A source-checked adult total length has not yet been added to this profile. Confirm it before choosing aquarium dimensions.
Planning context
The cited source supports this broad habitat classification. A verified husbandry protocol is not yet available here; do not treat natural habitat observations as an aquarium recipe.

Before choosing this species

Care-planning notes. Confirm exact requirements for the species and source population.

  • Confirm the adult size and social behaviour of the exact species before planning its aquarium.
  • Establish biological filtration and stable water conditions before introducing animals.
  • Ask for locality, captive history and the actual animal’s feeding record; a catalogue image cannot provide these.

Evidence record

Conservation record: Critically Endangered (CR); assessment year 2018. Conservation source record. This retained reference is an index or secondary record; the direct assessment and date require verification. Check for a newer assessment before making conservation or sourcing decisions.

Catalogue inclusion confirms a research record, not current stock, legal export, or destination-country import permission.
