Nasal barbel shorter than head length and tip of snout
dark. Large dark blotches on lower part of body, lighter
above. Akysid catfishes are known from across
a large area of Southeast Asia. Roberts (1989) described
them as small to minute fishes with cryptic colouration,
tiny eyes, and completely covered with unculiferous
plaques or tubercles. In some genera some of the tublercles
on the body are enlarged and arranged in distinctive
longitudinal rows, the number of which may be diagnostic.
Among akysids, fishes of the genus Akysis are very
small, cryptically coloured species generally found
in fast-flowing streams with a sandy or rocky bottom
and, until recently they have been poorly studied,
mainly due to the paucity of material in museum collections.
Akysis are easy to keep for any decent fishkeeper.
You can keep in small tanks (30cm wide x 20cm high
x 30cm deep) with a sand bottom, small pipes, and
caves. They will either bury themselves in the sand
or hide in caves and pipes. They are not usually active
during the day but will spring to action and eat voraciously
and crazily if food is put in the tank. Diet:
They will eat bloodworm, chopped earthworms, whiteworm,
daphnia, and sinking pellets (although they seem to
prefer live or frozen food).
