Size 140mm or 5.5" SL. Find near, nearer or same sized spp.
Identification Clarias species are characterized by having an elongated body; a soft rayed dorsal fin extending to, or nearly to, the caudal fin base; a soft rayed anal fin extending from just behind the anus to the caudal fin base; pectoral fins each with a serrated anterior bony spine; head depressed, covered largely by firmly sutured, surface sculptured bony plates forming a protective helmet; four pairs of flagellate barbels (nasals, maxillaries, inner and outer mandibulars); air breathing organs derived from the 2nd and 4th epibranchials within a superbranchial chamber.

Hypertrophied sensory canal pores on the head and body easily visible to the naked eye; having a long and thin anterior fontanel (except for Clarias batrachus); having prominent serrations on the anterior edge of the pectoral spine (except for Clarias intermedius, Clarias meladerma, Clarias olivaceus and Clarias planiceps); lacking white spots on the body (except for Clarias olivaceus and Clarias planiceps).
Sexing The genital papilla, which is to the right of the anus as you look at the fish with its head to the left, is elongated and pointed in males while it is round and relatively larger (and larger than the anus) in females. In ventral view especially, females are much broader in the body than males of equal age and rearing practices.
