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.

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, Sulawesi; including Lake Towuti
Identity
Ancient-lake Sulawesi ricefish

A subtly mottled ricefish from the Malili system. Lake Towuti specimens were examined in a 2024 DNA-barcoding study. Its lake provenance and identity must be kept distinct from other Sulawesi Oryzias.

Habitat and care

Freshwater lake habitat in the Malili system. Habitat and identity reference

Use lake- and locality-specific care information, a mature aquarium and verified captive provenance. Catalogue inclusion does not establish suitability for an ordinary community tank.

Design for feeding and movement

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

  • Check adult dimensions and social needs for this species; small body size alone does not establish aquarium suitability.
  • Provide swimming space and refuge, and choose companions with compatible feeding behaviour.
  • Match food size to the animal and observe feeding directly, especially when keeping small species with faster feeders.
