Not recommended for the standard community set-up for reasons already touched upon. It’s requirements and disposition mean it’s best kept alone or with very peaceful species since much bigger or more vigorous fishes are likely to intimidate and outcompete it.

Some small cyprinids and loaches that inhabit similar environments in nature are compat…

Gastromyzon zebrinus TAN, 2006

Much of the natural diet is likely to be composed of benthic algae plus associated micro-organisms which are rasped from solid surfaces.

Home-made foods usi…

Acanthopsoides robertsi SIEBERT, 1991

March 13th, 2012 — 1:25pm

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'. Most are very difficult to tell apart but A. robertsi is quite easily identified since it's the only…

This species is uncommon in the aquarium hobby. It is similar to the congeners C. borneensis and C. lorteti but can be told apart by males possessing a red (vs. bluish to greyish with black and white distal bands in C. lorteti) caudal-fin and lacking (vs. possessing) a black blotch at the base of the dorsal-fin.

Saddle-back Loach

Following Tan and Ng (2005) these share possession of…

Datnioides polota (HAMILTON, 1822)

Silver Tiger Perch

March 13th, 2012 — 1:18pm

D. polota is sometimes referred to as D. quadrifasciatus (Sevastianov, 1809) but the original name of the latter, Chaetodon quadrifasciatus Sevastianov, 1809, is a junior primary homonym of the older Chaetodon quadrifasciatus Bloch & Schneider 1801, thus Coius polota Hamilton, 1822 takes precedence.
