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.

Infrequently encountered in the aquarium trade, most often as bycatch among shipments of similar-looking congeners. It’s included in the P. kuhlii group of closely-related species within the genus, and can be distinguished from other members by…

Described from Sichuan province, southwestern China (presumably the upper Yangzte River, aka Chang Jiang, drainage) and also known from parts of the Pearl River (Zhu Jiang) basin in Guangxi Autonomous Region. The latter area is one of the most populous and industrialised in China meaning much of the main river channel is now highly polluted. Its relatively wide distribution probably explains why it’s commoner in the aquarium hobby than the similar-looking…

Should be kept in a set-up designed to resemble a flowing stream with a substrate of variably-sized rocks, gravel and some water-worn boulders. This can be further furnished with driftwood roots and branches arranged to form some shaded spots while lengths of PVC piping or similar can be used to provide additional cover. Although most plant species will fail to thrive in such surroundings hardy genera such as Microsorum, Bolbitis or Anubias spp. can be grown attached to the décor and bright lighting will promote the growth of aufwuchs.

L. taeniops is almost unheard of in the aquarium trade although we know of one or two private collectors maintaining it. It was previously included in the related genus Parabotia.

L. elongata is the type species of the genus but according to current knowledge there exist 13 members in total, all of which are endemic to China and northern Vietnam. They’re diagnosable by the following shared characters: possession of a simple (non-bifurcated), short sub-ocular spine not extending beyond the posterior edge of the eye; a laterally-compressed body; relatively deep caudal peduncle; pelvic fins reaching origin of anal-fin; anus below base of dorsal-fin and equidistant between pelvic and anal-fin origins.

Superficially similar to L. tientainensis but according to the formal description can be separated by a combination of characters including: more deeply-forked caudal-fin (shortest central rays fit 2.6-2.9 times in the outer rays vs. 1.7-2.5 times); significantly smaller eye (fits 26 times in head length vs. 10 times); caudal-fin with 1-2 dark bands at lateral edges v…

L. disparis is sometimes available as bycatch among shipments of other species such as Rhinogobius duospilus but also appears on trade lists under the fictitious scientific name ‘Homaloptera hoffmani’.

It can be told apart from similar-looking members of the genus Formosania by its noticeably shorter barbels and from Vanmanenia spp. by the fact that the rostral fold is not lobed and the mouth is relatively small (25% head width. In addition the lower lip in Liniparhomaloptera is not divided and has a flat, papillated edge.

This species is rare in the aquarium trade, increasingly so in nature and as a result prohibitively expensive when available. Given its adult size and probable longevity this is therefore a species for the specialist possessing the necessary time, money and dedication to house it long term.
