Short description

Dorsal soft rays (total): 19 - 24; Anal soft rays: 25 - 30

Occurs in shallow and muddy waters, sheltered bays, in lagoons, and swampy areas. Forms shoal (Ref. 13337). Prefers quiet parts of rivers where there is abundant vegetation (Ref. 13337). Feeds mostly on insect larvae and other invertebrates at night (Ref. 5595). Shoals within quiet reaches of rivers and floodplains. Oviparous (Ref. 205). Known to undergo upriver migration which may well be correlated with breeding (Ref. 13337). Breeds during the rainy season, possibly moving upstream to suitable sites. An unconfirmed report claims the males are territorial and build a nest (Ref. 7248). Found schooling with other species with identical electric organ discharge (EOD) waveforms (Ref. 10460). Caught in nets for food (5214).
