The type series was collected from a blackwater stream in Toh Daeng Peat swamp forest with the fish found in slow-moving or standing habitats among submerged shoreline roots and leaf litter. In the Tapi River floodplain it was collected from stagnant waters, one of which was an oxbow lake approximately 200 m long and 30 m across at its widest point, surrounded by 'freshwater scrub and swamp trees'. The substrate was composed of mud, woody structures including fallen twigs and branches, and decomposing plant material.

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

Aquarium size

An aquarium with base dimensions of 40 ∗ 20 cm or more is sufficient.

Maintenance

Fares best in a well-planted set-up with a soft substrate although fine-grade gravel is acceptable. Driftwood roots or branches, floating plants and leaf litte…

Diet

Chiefly a micropredator feeding on tiny aquatic crustaceans, worms, insect larvae and other zooplankton. In the aquarium it does not accept dried or frozen pro…

Behaviour and compatibility

A poor competitor and will be preyed upon by larger fishes so it's best kept alone or with similarly-sized, placid species such as members of Boraras, Danionel…

Sexual dimorphism

Adult males possess broad, elongated pelvic fins with the outer rays curved inwards, while in females the pelvic fins are straight and more slender. Gravid fem…

Reproduction

Has been bred in aquaria on numerous occasions. Spawning occurs in small caves or crevices including artificial alternatives such as small lengths of bamboo or…

Notes

This species can be told apart from congeners by the following characters: presence of dark brown to black bars in dorsal and anal fins of males; ventral surfa…
