The species has been collected from localities connected with the rivers Mempawah and Kepayang close to the town of Anjungan in Kalimantan Barat (West Kalimantan) province, Borneo, Indonesia.
Type locality is ‘Sungei Kepayang, 7 kilometers southeast of Anjungan on road to Pontianak, 0°20’N, 109°08’E, Kalimantan Barat, Borneo’.
A stenotypic inhabitant of peat swamp forests and associated black water streams.
The dense canopy of branches above means very little light penetrates the surface of such environments, and riparian vegetation also tends to grow thickly.
The water is typically stained darkly with humic acids and other chemicals released by decaying organic material.
The dissolved mineral content is generally negligible and pH can be as low as 3.0 or 4.0.
The substrate is usually covered by fallen leaves, branches and submerged tree roots and at certain times of year the fish may be forced to survive within the moist leaf litter for several weeks as permanent water is not always available.
Maximum Standard Length
30 – 35 mm.
Temperature: 22 – 27 °C
pH: 3.0 – 6.0
Hardness: 18 – 90 ppm
Likely to prey on insects and other small invertebrates in nature.
Captive fish will normally accept dried products once they’re recognised as edible, but should be offered plenty of small live or frozen foods such as Daphnia, Artemia or bloodworm regularly to ensure development of optimum colour and condition.
Take care not to overfeed as Betta spp. seem particularly prone to obesity.
