Aquarium size

An aquarium with a base measuring 60 ∗ 30 cm or more is recommended.

This species is rare in the aquarium hobby and may only have appeared as bycatch among shipments of other species to date.

It's characterised by body patterning consisting of 13-17 irregularly-arranged dark blotches along the lateral line and a further 13-17 saddle-like markings across the dorsal surface.

In some specimens/populations the dorsal and lateral markings are connected. Other features include possession of (usually) 16 branched caudal-fin rays, 9-10½ branched dorsal-fin rays and positioning of the anterior nostril at the 'extremity of an obliquely-cut tube with pointed tip' (Hadiaty and Kottelat, 2010)[3].

Following Kottelat (1990) the genus Nemacheilus is characterised by a combination of characters as follows: elongate body; complete lateral line; presence of enlarged scales above and below the lateral line in some species; caudal-fin forked to deeply forked with enlarged upper lobe; large eye; small, strongly arched mouth; lips usually thin; usually no median interruption in upper lip; upper jaw with processus dentiformis (a tooth-like projection); no median notch in lower jaw; long barbels; males usually with suborbital flap, pectoral-fin rays 2-6 thickened and with rows of tubercules.

The family Nemacheilidae is widely-distributed across most of Eurasia with the Indian subcontinent, Southeast Asia and China representing particular centres of species diversity.

Where does this come from?

My own experienceFor example, I've kept twelve in a planted 60 cm tank since March 2024.A website I sawFor example, an IUCN Red List assessment, a museum catalogue or a FishBase page.A paperFor example, Marshall et al. (2011), Water temperature differences in interfluvial palm swamp habitats of Paracheirodon axelrodi and P. simulans.A book, or something not onlineFor example, Tappin (2010), Rainbowfishes: their care and keeping in captivity.Something already on the pageFor example, the Behaviour and compatibility section already says this.
