Betta simorum

$20.00

This species has been collected from various localities in the province of Jambi, Sumatra, the adjacent province of Riau, and the Kapuas River system in Kalimantan Barat (West Kalimantan) province, Borneo.

The type specimens were collected from ‘Swamp in Rantau Panjang, Jambi Province, Sumatra, Indonesia’, not to be confused with the town of the same name on the Thai-Malay border, whilst in Riau the species appears restricted to the Indragiri river basin.

Populations from different localities are often labelled as such by collectors and enthusiasts in order to maintain accuracy and preserve pure bloodlines, e.g., Rantau Panjang, Pematang Lumut (both in Jambi), Sungai Bengkwan (Riau), etc.

Inhabits heavily-vegetated forest peat swamps and associated black water streams.

These ancient biotopes are usually found in areas of rainforest, the dense canopy of branches above meaning very little light penetrates the water surface with riparianvegetation tending 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 the 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.

80 – 90 mm.
