পৃষ্ঠীয় কাঁটা (মোট ) : 1; পৃষ্ঠীয় নরম পাখনা দন্ড (মোট ) : 6; পায়ূর নরম পাখনা্তুন্ড: 11 - 13. The body is a little elongated, without scales but with a lateral range of 24 to 28 bony plaque. Head is large and rounded. Mouth is nearly terminal and has three pairs of barbels (Ref. 35381).
Occurs in freshwater coastal swamps and the flood-prone zones of rivers. Gregarious, lives schools which may consist of several hundred fish. Hides under roots, leaves or stocks. Is known to build a nest of bubbles at the surface, defended by the males as the 'Atipas' do. In case of drought, it is reputed to being very resistant and to crawl in search of a new swamp while holding some water in its ears. Feeds on algae and debris (Ref. 35381).
