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.

Identity and origin

Origin
Lake Poso, Sulawesi, Indonesia
Identity
Described freshwater species; lake/catchment endemic

Described in 2021. Larger females can be white with broad red stripes or blotches; males are often much more transparent. These sex-related differences are not separate varieties.

Habitat and care

Empty Celetaia and Tylomelania snail shells in deeper water; surveyed shells at 7 m and shallower held no shrimp. Habitat and identity reference

Specialist research profile. Match the documented microhabitat; reliable species-specific captive requirements have not been established by the sources used here. Lake depth, sponge association or shell use is ecological evidence, not a proven aquarium recipe.

Plan before choosing

Habitat
Ancient lakes
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.

Varieties and trade names

  • Red-and-white female / translucent male

    Sex-related variation

    Colour differences between sexes must not be sold as distinct species or stable grades. Source

Evidence record

Conservation record: Not Evaluated (NE); assessment year —. 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.
