Has been bred for several years in captivity at Sri Chiengmai Fisheries station (near Nongkhai) and elsewhere in Thailand (Ref. 7431). Threatened due to habitat loss and overfishing (Ref. 58784). Also Ref. 1632, 12255, 9648, 26336, 27732, 36654, 43281. In range Ref. 12041. Status of threat: Endangered (Ref. 58784).

Descrição breve Chaves de identificação | Morfologia | Morfometria

Distinguishable by the presence of numerous small black spots (in the anterior half of the body), merging posteriorly into irregular oblique bands extending on the anal and caudal fins (Ref. 27732). Differs from all other species except C. lopis in having a large round black spot at base of pectoral fin. In C. blanci pectoral basal spot present in juveniles as small as 6 cm and retained throughout life (Ref. 7431).

Facultative air-breathing (Ref. 126274); Apparently restricted to areas with fast flowing waters, deep pools or rapids (Ref. 27732). Prefer habitats associated with rocky substrates (Ref. 37770). Occur in the mainstream of the Mekong River. Avoids tributaries and swamps (Ref. 7431). Reported to undertake short, local migrations (Ref. 37770). Active during twilight and night. Feed on fishes, crustaceans and insects. Also take smaller vertebrates (Ref. 58784). Spawning sites are found in inundated forests (Ref. 33813). Mature adults breed during the rainy season. Occasionally seen in the aquarium trade. (Ref. 12693). Has been bred for several years in Thailand (Ref. 7431).
