Description of life cycle and mating behavior The pair manifests the 'spawning embrace' which is widely observed in other catfish species (Ref. 33313). The pair gently nudge each other in the genital region and flick their dorsal fins; male wraps his body around the female, then the female releases a stream of adhesive eggs into the nest (Ref. 44091). In southeast Asia, spawning period is during the rainy season, when rivers rise and fish are able to excavate nests in submerged mud banks and dikes of flooded rice fields (Ref. 40977).
