Common in tanks throughout the greater parts of India. Feeds on insects, fish , crustaceans and some young roots of aquatic plants. Active during twilight and night. Colonizes and breeds seasonally during rainy days and migrates back to permanent waters in dry season. Breeding takes place in stagnant or running waters in the rainy season. Eggs are laid in small clumps on submerged vegetation. A female measuring 21-25 cm usually lays 1,200-3,000 eggs. The fish is relished b
