Description
edithae: named for Edith Korthaus who was involved in the discovery of this species and many other fishes from Borneo.
Distribution
This species is known only from the Greater Sunda Islands region in Indonesia.
Type locality is ‘Barito River delta, Banjarmasin, Borneo Indonesia’ which corresponds to the town of Banjarmasin in South Kalimantan (Kalimantan Selatan) province.
It’s subsequently been recorded over a large range including all four provinces of Kalimantan as well as near Palembang in South Sumatra (Sumatera Selatan) province, Sumatra and the islands of Bangka, Belitung (together forming Bangka-Belitung province) and Bintan (Riau Islands province).
It remains unclear whether all the populations are conspecific or not, with fish from Bintan differing from Bornean specimens in several characters (see ‘Notes’), while those from Palembang resemble the population from Bangka.
Habitat
Found in various habitat-types from flowing, black water streams where it tends to inhabit stiller, marginal areas among submerged roots, leaf litter or overhanging vegetation, to sluggish, artificially-modified canals inside oil palm plantations.
Maximum Standard Length
55 – 60 mm.
Water Conditions
Temperature: 20 – 27 °C
