पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 3; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 5 - 6; गुदा कांटा: 3; ऐनल सौफट रेज़: 8 - 11; जानवरों की रीड़ का जोड़: 49 - 50. Broad midlateral stripe from eye to caudal base and narrow stripe from opercle at least to pelvic origin. Lamina circularis absent in males (Ref. 59043). Caudal fin with 14-16 rays (Ref. 40476).
Body shape (shape guide): elongated.
Facultative air-breathing (Ref. 126274); Found in lower reaches of slow-flowing rivers, but can also be found in still pools (Ref. 9696), on sandy bottoms of ponds, pools and ditches. Adults are nocturnal which burrow into mud during dry periods and strong frosts. Usually, burrows are 20-30 cm deep, occasionally down to 70 cm during dry periods (Ref. 59043). During the day, they stay buried in the sand. Feed on insect larvae and small mollusks. Seldom captured with hook and line (Ref. 30578). Are sensitive to pollutants which accumulate in the sediment (Ref. 11941). Facultative air-breathers (Ref. 27368). A female specimen measuring 30.7 cm TL was recorded from Netherlands (Ref. 114650).
Male follows female into dense vegetation and forms a complete ring around her body, behind dorsal fin (Ref. 59043).
