Ecologia
; Água doce; estuarina bentopelágico; pH range: 6.5 - 8.0; dH range: ? - 25; intervalo de profundidade 10 - ? m (Ref. 9987). Tropical; 20°C - 30°C (Ref. 13371); 6°N - 9°S
Asia: probably limited to Sumatra, Borneo, Java, the Malay Peninsula, Thailand and Indochina (Mekong basin). Has been introduced to several countries for aquaculture purposes. Apparently absent in Sarawak and presence in Sabah may be due to relatively late introductions.

Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 12 - 14; Raios dorsais (total) : 10 - 13; Espinhos anais: 9 - 13; Raios anais : 18 - 21; Vértebras: 30 - 31. With 8-10 complete dark vertical bars in juvenile color phase; adults without vertical bars or sexual dichromatism, both sexes drab; transverse scale rows usually 6.1.12; dorsal fin spines usually 12-13 (rarely 11 or 14); soft-rayed portion of anal fin greatly enlarged, its distal margin parallel to distal margin of caudal fin; caudal fin rounded or obtusely rounded, not truncate or emarginate (Ref. 7425). Pelvic fins with first soft ray prolonged into a thread-like tentacle reaching posteriorly to or beyond hind margin of caudal fin.
Obligate air-breathing (Ref. 126274); Inhabits swamps, lakes and rivers (Ref. 9987), among vegetation (Ref. 56749). Enters flooded forest (Ref. 9497). Found in medium to large rivers and stagnant water bodies including sluggish flowing canals (Ref. 12975). Omnivorous. Feeds on both plants and animals such as some aquatic weeds, fish, frogs, earthworms and sometimes dead animals (Ref. 6459). Can breathe moist air, so can be kept alive for long periods out of water, making it possible to distribute it in areas lacking a cold chain (Ref. 9987). Was reported from miocene deposits in Central Sumatra (Ref. 7426). Utilized fresh and eaten steamed, pan-fried and baked (Ref. 9987).

Adults make nests made of plant fibers instead of bubble nests as some publications have claimed (Ref. 127550). This error comes from a misidentification of a species according to Bhimachar et al. (1944).
