পৃষ্ঠীয় কাঁটা (মোট ) : 6 - 7; পৃষ্ঠীয় নরম পাখনা দন্ড (মোট ) : 6 - 8; পায়ূ কাঁটা : 1; পায়ূর নরম পাখনা্তুন্ড: 5 - 8. Distinguished by the following characteristics: relatively large size; second dorsal rays I,6-8; pectoral rays 15-18; segmented caudal rays 15-17 (modally 16); longitudinal scales 25-34; TRB 8-12; predorsal scales 10-19; shoulder girdle with smooth low ridge or flange, rarely with fleshy lobes; mouth terminal, large, greatly enlarged in mature males (maxillary sometimes extending past rear edge of preoperculum); each scale on side of body with short dusky bar; two distinct brown stripes extending back from rear of eye and two from eye to snout tip; dark fins, dorsal fins distinctly spotted with brown (Ref. 80545).
A euryhaline species (Ref. 12041). Occurs in estuaries, primarily in slow flowing canals and smaller bodies of water. Feeds on small fishes and invertebrates, including mosquito larvae and entomostracans (Ref. 12693). The following aquarium observations describe its captive behavior and breeding: strictly benthic and quite secretive; males constructed nests under flat stones, shoveling sand with their large mouths while pieces of gravel (up to 12 mm diameter) are carried one by one; males display to each other with mouths wide open and may push against each other jaw to jaw, if observed may often switch to locking jaws (as if biting); about 1,000 eggs per batch (1.5 x 0.5 mm) and hatched after 44-95 hours at 25°C; larvae 2.4 mm long and floated up near the water surface until yolk absorbed after 124 hours, these then moved down into the water column (Ref. 80545). Not seen in the markets (Ref. 12693); rarely collected (Ref. 80545).
