Batasio spp. are obligate inhabitants of headwater streams and the upper reaches of smaller rivers characterised by shallow, fast-flowing, highly-oxygenated stretches of riffles and runs broken up by pools or cascades in some cases. Images of the Ataran correspondingly depict flowing sections of forest-shaded, seemingly well-oxygenated headwaters containing clear water, a mixed sand/rock substrate and lots of submerged driftwood/leaf litter.

B. obscurus is diagnosable from congerners by the following combination of characters: mouth opening relatively small and narrow; oral dentition significantly reduced; dorsal-fin spi…

Orange-Banded Stream Catfish, Wasp Stream Catfish, Wespenwels (DE)
March 13th, 2012 — 1:26pm
This species is among the few members of the family to be exported for the aquarium hobby and we’ve also seen it on sale under various names such as ‘orange-banded stone catfish’, ‘orange micro bumblebee catfish’, ‘Burmese orange mini bee catfish’ or more simply ‘wasp catfish’. Though the majority of forms are yellowish to orange in colouration there appears to exist a bright red variant which to date we’ve only seen in photos.

Falcate Chameleon Catfish

As in other members of the genus body colouration in this species is variable, even among individuals collected from a single locality, although a few regularities have been observed which can be used to distinguish certain species from one another. This is thought related to the fact that Acrochordonichthys spp. periodically shed their skins and appear paler post-moulting.
