Habitat and Ecology [top]

Habitat and Ecology:Inhabits lowland fresh and brackish waters; rivers, lakes, ponds and reservoirs. This species has a short spawning period during July-August, coinciding with the south-west monsoons. Also breeds in confined waters of ponds and tanks. Often migrates to nearby inundated pools and puddles for breeding during rainy season. Inundated paddy fields are most preferred spawning grounds.

This catfish is abundant in ponds and rivers, and in the mud they lie concealed for hours. Found in all types of waters but more so in derelict and swampy waters. It can live out of water for quite sometime and move short distances over land as it has an accessory respiratory organ.
Movement patterns:Full Migrant
