Chela cachius (HAMILTON, 1822)

Neon Hatchet Fish

August 24th, 2014 — 7:52pm

It is currently the only valid member of the genus but it is possible that additional taxa exist, particularly in Myanmar, while a number of former species are contained within the Laubuka assemblage, to which C. cachius is closely related. Phylogenetic studies suggest the existence of a monophyletic clade consisting of the genera Devario, Chela, Laubuca, Microdevario and Microrasbora plus the genus Betadevario.

Amblypharyngodon chulabhornae VIDTHAYANON & KOTTELAT, 1990

August 23rd, 2014 — 7:16pm

The genus Amblypharyngodon currently contains five valid species, and A. chulabhornae can be distinguished from congeners by the following combination of characters: 42-50 (vs. 50-79) scales in the lateral row; lateral line incomplete with 6-7 (vs. 7-23) perforated scales; 4-5 scales on a transverse row between the lateral line and pelvic-fin base. All members of the genus lack barbels.

Devario sp. 'purple cypris'

July 29th, 2013 — 4:37pm

This unidentified species has only appeared in the aquarium trade on a handful of occasions and it has been widely misidentified as Devario jayarami (Barman, 1984).

It differs from D. jayarami by possessing 9-10 lateral bars which progressively increase in size posteriorly (vs. 12-13 bars which decrease in size posteriorly), 12 anal-fin rays (vs. 15-16) and a blunter head profile with a lack of convexity behind the head (vs. head profile conical with noticeable convexity behind the head).

Devario sp. 'giraffe'

July 29th, 2013 — 4:03pm

This unidentified species was first collected in 2007 but very little is known about it.

The vernacular name refers to the colour pattern on the body which resembles that of a giraffe, and it’s known to be collected in Myanmar although its distribution and natural habitat remain a mystery.

Devario xyrops FANG & KULLANDER, 2009

Blue Moon 'Danio'

July 29th, 2013 — 3:23pm

Thrives in an aquarium set up to resemble a flowing stream or river with a substrate of variably-sized, water-worn rocks, sand, fine gravel and perhaps some small boulders.

This can be further furnished with driftwood roots or branches, and while the majority of aquatic plants will fail to thrive in such surroundings hardy types such as Microsorum, Bolbitis or Anubias spp. can be grown attached to the décor.

Devario affinis (BLYTH, 1860)

November 28th, 2012 — 4:42pm

Type locality is ‘Tenasserim, Myanmar’ which at time of description was used to refer to the portion of Myanmar lying to the south and east of the Ayeyarwaddy/Irrawaddy river delta, including present-day Kayah, Kayin, and Mon states, Bago Division, and possibly the southern Tanintharyi Region.

Blyth’s description paper covered fishes collected from the Sittaung River (plus a few Gangetic species) in what is currently Bago Division, but we’ve been unable to locate any modern records of D. affinis fro…
