Etymology

Oryzias: from the Greek ὄρυζα (oryza), meaning 'rice', in reference to the tendency of some members of the genus to inhabit rice paddy fields. celebensis: 'fro…

Distribution

Described from the Maros River (Salo Maros), southwestern Sulawesi, Indonesia and subsequently recorded from rivers and streams throughout the southwestern arm…

Habitat

The Maros area is mostly karstic meaning the rivers and streams there tend to flow over limestone, though not all habitats feature such conditions. O. celebens…

Aquarium size

An aquarium with base dimensions of 45 ∗ 30 cm or more is recommended for a group.

Maintenance

Best maintained in a heavily planted set-up, ideally with a dark substrate, patches of dense vegetation, and some open areas.

Other décor can consist of twisted roots and pieces of bogwood, while surface vegetation is also appreciated by the fish.

When maintained under such conditions they're more likely to display their best colours, and planted aquaria also offer fry a more favourable chance of survival alongside the adults.

Where does this come from?

My own experienceFor example, I've kept twelve in a planted 60 cm tank since March 2024.A website I sawFor example, an IUCN Red List assessment, a museum catalogue or a FishBase page.A paperFor example, Marshall et al. (2011), Water temperature differences in interfluvial palm swamp habitats of Paracheirodon axelrodi and P. simulans.A book, or something not onlineFor example, Tappin (2010), Rainbowfishes: their care and keeping in captivity.Something already on the pageFor example, the Behaviour and compatibility section already says this.

Anything worth adding

Describe what you saw, or which part of the source says this.

Water conditions

Temperature: 23 – 27 °C pH: 7.0 – 9.0; will probably fail to thrive if maintained long term in acidic water. Hardness: 5 – 25 dGH

Diet

Probably a micropredator feeding on small insects, worms, crustaceans and other zooplankton in nature. In the aquarium it will accept dried foods of a suitable…

Behaviour and compatibility

Generally peaceful but doesn't make an ideal addition to many communities due to its small size. Should you wish to maintain it alongside other fishes diminuti…

Sexual dimorphism

Adult males are considerably more colourful, possess longer dorsal and anal fins, and have a slimmer body shape than females. In males the distal margin of the…

Reproduction

Quite easy to breed and fairly prolific, with females capable of producing batches of eggs every few days or even on a daily basis when in good condition. Spaw…

Notes

This species is infrequently available in the aquarium hobby but is exported on occasion and sometimes referred to as 'Celebes medaka'. It has a truncate, rath…
