古晋无须魮 · False Spanner Barb

Overview

Rarely exported in its true form, Barbodes kuchingensis is often confused with other patterned barbs. A line of distinct dark spots along the lateral line and a short streak behind the upper gill cover are particularly useful recognition features.

Distribution & habitat

It appears restricted to western Borneo, extending from Sarawak into the Kapuas drainage of West Kalimantan, including the Danau Sentarum lakes. Clear, shallow forest streams and waterfall pools are common habitats. Stones, sand, wood, leaves and plants form a varied bottom, with flow changing between sites and seasons. Records also include peat swamps and mineral-poor blackwater streams.

Aquarium setup

A stream arrangement of sand, gravel, smooth rocks and wood is appropriate, with tough attached plants where desired. Maintain clean water, good oxygenation and moderate circulation. Weekly changes of about a third to half of the water help prevent organic pollution; a torrent-like current is unnecessary.

Diet & feeding

Diatoms, other algae, debris and small animal foods are thought to be taken in nature. Provide quality dry foods with some plant or algal content, supplemented by varied live or frozen invertebrates.

Behaviour & compatibility

Peaceful, robust river fishes of similar size are suitable candidates. Companions should be large enough to avoid being treated as prey and confident enough to tolerate an active shoal. Eight to ten conspecifics are suggested to improve security and keep most social disputes within the group.

Sexual dimorphism

Males show stronger colors and reproductive tubercles on the head. Females generally become larger and deeper-bodied, with less intense coloration.

Notes

Trade labels may refer to subadults of other species or to geographically variable forms. Check the separated lateral spots and the short upper opercular streak, rather than relying on the label; a continuous flank stripe alone does not establish this identification.
