Scientific Name	**Ceratoglanis scleronema** (Bleeker, 1863)
Common Name
Type Locality	Krawang, Java, Indonesia.
Synonym(s)	Hemisilurus scleronema
Etymology	From the Greek keratos, meaning horn and glanis, meaning catfish. The specific name comes from the Greek skleros, meaning hard and nema, meaning thread. Both names refer to the stiff, hooked maxillary barbels characteristic of this genus.
Species Information
Size	440mm or 17.3" SL. Find near, nearer or same sized spp.
Identification	Differ from the only other congener, C. pachynema, in having more fin-rays, smaller eye, and mature males with membranous extensions only on the front edge of the maxillary barbel.
Sexing	Males have membranous extensions to the maxillary barbels and prominent serrations on the posterior edge of the pectoral spine, which females lack.
General Remarks	This species is hard to maintain in the home aquarium. It requires vast amounts of swimming room, and experience in the field indicates that it is extremely sensitive to shock, dying very quickly after capture.
