IUCN CRCritically Endangered
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. 21 · 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 catchment rivers and a record from the Tomori area, Sulawesi, Indonesia
Identity
Described freshwater species; riverine

An exclusively riverine shrimp with variable yellow-brown transparency. It is not restricted to Lake Mahalona or even solely to the Malili catchment.

Habitat and care

Vegetation, roots, dead wood and leaf litter in streams. A published morphology plate is shown instead of an invented live photograph. Habitat and identity reference

Match a documented stream locality rather than applying an ancient-lake mineral recipe. Use a mature, well-oxygenated system and verify feeding and reproduction from a traceable captive colony. No universal temperature or pH range is established here.

Plan before choosing

Habitat
Catchment rivers
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.

Source check: . Independent husbandry review pending.

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.
