Batasio havmolleri (Smith, 1931) is currently considered a junior synonym of B. fluviatilis.

Members of the genus Batasio are characterised by the following combination of characters; laterally-compressed body shape; presence of large sensory pores on the head; a narrow mental region; a pair of prominent posterior proces…

The genus Barbonymus was erected by Kottelat in 1999 and contains former members of Barbodes from southeast Asia. The type species is B. schwanenfeldii and currently there exist only three other representatives; B. altus, B. collingwoodii and B. gonionotus.

The latter two are rare in the hobby although an SF member has kept B. gonionotus in the past so they are worth looking out for if you harbour an…

This species is among the few members of the family to have been exported for the aquarium hobby. It can be differentiated from all other Akysis species by the following combination of characters: head length 17.7-26.5% of standard length (SL); head width 25.4-28.7% SL; body depth at anus 13.0-17.0% SL; caudal peduncle depth 8.1-10.1% SL; interorbital di…

One of a handful of Pangio spp. traded under the generic name ‘eel loach’. Wild populations tend to differ in colour pattern to some extent, with some exhibiting a more intense lateral stripe while others display an irregular pattern of fine dark spots on the body, for example.

Acanthopsoides spp. are most closely related to the horse-faced loaches of the genus Acantopsis with which they often co-occur in nature, and thus commonly referred to as 'dwarf horse-face loaches'. The genus currently comprises five species of which four were described by Siebert (1991); these were discovered in existing museum holdings…

According to Kottelat (1990) the chief distinguishing characters for the genus are: possession of 9-18½ branched dorsal-fin rays; colour pattern without black basal caudal bar, but with an ocellus at upper base of caudal-fin; upper lip with or without several rows of papillae; lower lip with a broad median interruption and a widened, papillated pad on each side.

Also known by the vernacular names ”black band garra’, ‘stone-lapping minnow’ or ‘false flying fox’ and continues to be traded as Garra taeniata, an invalid name synonymous with G. cambodgiensis.

It is often confused with those laterally-striped members of the genus Crossocheilus sold as ‘Siamese algae eater’ or ‘Siamese flying fox’, but in those species the dark lateral body stripe continues into the caudal-fin whereas in G. cambodgiensis it terminates…

It can be distinguished from congeners by the following combination of characters: 61-68 scales in the lateral series; a small, well-defined, sometimes ocellated black spot on the shoulder and another in the centre of the caudal peduncle; body without longitudinal stripes formed by spots on scales; caudal fin uniformly dusky or colourless, lobes without stripes or black margins.

In the aquarium trade this species may also be seen on sale as ‘skinhead barb’. As with others in the genus little has been written regarding its captive care but it makes a peaceful and unusual addition to larger aquaria. The best way of obtaining it may be to keep an eye on shipments of wild fishes from Indochina and the Greater Sunda Islands as it’s rarely imported in large numbers and most often arrives as bycatch.

The identity of this species was unclear for a number of decades prior to its redescription by Ng and Kottelat (2013).

The confusion originated with Brittan (1954) who misidentified specimens of R. tornieri as R. dusonensis and was exacerbated by Alfred (1963) who concluded that the holotype of R. dusonensis was conspecific with R. myersi.
