Relevant Information:

Habitat: This species is known from the Siak River drainage southwards to the Musi River drainage in Sumatra, and from the Kapuas, and the Sampit (Mentaya) River drainage eastwards to the Sebangau River drainage in Borneo. Extent of occurrence (EOO) is estimated to be 540,000 km2, based on georeferenced points (GBIF 2019) and expert opinion (H.H. Ng pers. comm. 2019). The number of locations where this species occur is unknown. However, given its broad distribution it is likely greater than 10. This species inhabits both lotic and lentic habitats; it appears to be more closely associated with blackwater peat swamp habitats. Reproduction: Oviparous, eggs are unguarded. Aquarium Care: Quite a shy fish so would need a planted tank to make them feel safe in their surroundings. Have at least 6 to form a group. Diet: Feeds on insect larvae and small invertebrates. Etymology: The specific name brachypopterus: brachýs, short; –po, abridgement of hypó, under or less than; pterus, from pterón or ptéryx, wing or fin referring to shorter anal fin compared with Asian and African congeners then placed in Eutropius (=Schilbe, now in Schilbeidae). Remarks: Found alongside P. moolenburghae where they school together.

IUCN Red List

Although there is no detailed information on the population status of this species, survey data indicates that it is still abundant in many parts of its known distribution. It is therefore assessed as Least Concern. However, it should be noted that the primary habitat of this species (blackwater peat swamp forests) has undergone large scale destruction and degradation, and the effects of such massive habitat loss on the species should be further studied. It will be necessary to reassess this species once more information on the effect of habitat loss on the population is available (IUCN 2019).
