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
Java and wider coastal Southeast Asia
Identity
Native ricefish with freshwater and brackish habitats

A small ricefish reaching about 4.5 cm total length. Its freshwater–brackish ecology makes collection locality and salinity history relevant; it should not be confused with Sulawesi lake-endemic Oryzias.

Habitat and care

Vegetated coastal freshwater and brackish habitats. Habitat and identity reference

Provide planted cover and small foods; match the established salinity history of the verified line.

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.
