Bagarius yarrelli (SYKES, 1839)


February 8th, 2014 — 5:49pm

This species is clearly unsuitable for the home aquarium given its eventual size and natural behaviour, and we know of only a handful of private aquarists with the facilities required to house it long-term.

The grouping currently contains four species but is in urgent need of review with a number of additional taxa thought to exist and B. yarrelli possibly representing a synonym of B. bagarius.

Schistura oedipus (KOTTELAT, 1988)

It’s known from five caves in total, the others being Tham Huet, Tham Ban Louk Kow Larm, Tham Nong Pha Cham, and Tham Mae Lana.

Streams flowing from these caves drain into the Nam Lang and Nam Khong rivers of the Salween drainage system, and the two easternmost caves, Tham Huet and Tham Nong Pha Cham, are both tributaries of the former.

Havird and Page (2010) differentiate the two based on caudal-fin patterning, predorsal length and ver…

January 2nd, 2013 — 2:25pm

Homalopteroides spp. are specialised micropredators feeding on small crustaceans, insect larvae and other invertebrates.

In captivity some sinking dried foods may be accepted but regular meals of live or frozen Daphnia, Artemia, bloodworm, etc., are essential for the maintenance of good health.

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…
