Nonn Panitvong (1) Fishes of Mainland Southeast Asia (1)

Description: Dorsal soft rays (total): 5-6; Anal soft rays: 9 - 11; Vertebrae: 33. Distinguished from all its congeners by the following combination of characters: round head when viewed dorsally; presence of 1+3 gill rakers on the first branchial arch and 4-5 serrae on the posterior edge of the pectoral spine; depth of caudal peduncle 7.3-14.1 % SL; length of maxillary barbel 61-121% HL; length of inner mandibular barbel 33-74% HL; and caudal fin emarginate. 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). Etymology: The genus name Akysis: A = without; kysis = bladder, in reference to the lack of a swimbladder. The specific name ephippifer: ephippium, saddle; fero, to bear, referring to the saddle-shaped markings on body.
