Known from a handful of localities in Kalimantan Tengah (Central Kalimantan) province, and around the settlement of Kubu in Kalimantan Barat (Western Kalimantan) provinces, Indonesian Borneo.
Type locality is ‘Mentaya River system, 250 kilometers northwest of Bandjarmasin, Borneo, Indonesia’.
Typically inhabits forest swamp streams and pools, some of which have been measured at just a few centimetres deep. These are usually shaded from the sun, the dense canopy of branches above meaning very little light penetrates the water surface.
Marginal vegetation also tends to grow thickly. The water itself is often stained with humic acids and other chemicals released by decaying organic material. The dissolved mineral content is negligible, pH low, and substrate composed mainly of fallen leaves, branches, and submerged tree roots.
Maximum Standard Length
40 – 50 mm.
Temperature: 22 – 28 °C
pH: 4.0 – 6.0
Hardness: 18 – 90 ppm
Likely to prey on aquatic and terrestrial invertebrates in nature.
Captive fish will normally accept dried products once they are recognised as edible, but should be offered plenty of small live or frozen foods such as Daphnia, Artemia or chironomid larvae (bloodworm) regularly to ensure development of optimal colour and condition.
Take care not to overfeed as Betta spp. seem particularly prone to obesity.
