Maximum Length : 14 cm
This small, elusive
catfish inhabits clear, unpolluted, acidic forest streams and freshwater
swamp forest habitats.
By day it lies concealed amongst stream-side vegetation or beneath submerged
logs or stream-bed leaf litter. By night it becomes active and can be
found patrolling surface water in its search for insects and other
foodstuff.
The caudal fin (tail fin) of the species merges unbroken with the long anal
fin, forming a single elongated fin which extends along most of the
underside of the fish. Undulation of this fin gives the fish an attractive,
sinuous swimming motion.
The species ranges from Indochina to Peninsular Malaysia, Singapore and
parts of Indonesia including Borneo and Sumatra.
