Dorsal soft rays (total): 5-6; Anal soft rays: 8 -
10; Vertebrae: 31 - 33. Distinguished from all its
congeners by the following unique combination of characters:
truncate caudal fin; length of caudal peduncle 16.1-19.8%
SL; depth of caudal peduncle 6.5-9.3% SL; length of
adipose-fin base 25.6-29.5% SL; interorbital distance
42-46% HL; eye diameter 13-20% HL; length of nasal
barbel 44-66% HL; straight lateral margins of the
head when viewed dorsally; and 0-5 serrae on the posterior
edge of the pectoral spine. Aquarium
Care: 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). Remarks: The first thumbnail
specimen was collected by the image contributor in
the Phitsanulork Prov. Upper Choa Phraya, Thailand.
Although it is similar to Akysis varius ,
which comes from the Mekong drainage, this is from
the Phraya drainage so it may be an undescibed species.
