📖 Overview

Found in still and flowing waters; often abundant in dams and lakes, usually among weeds or over mud bottoms. Occurs in reservoirs and brackish estuaries, less common in gently flowing streams . Feeds on crustaceans, insects, other fishes and tadpoles . In breeding season (mainly spring to summer), males darken and display more vibrant fin markings. Females lay a clutch of eggs on a hard surface such as a rock or piece of wood. The male cares for the nest, chasing away intruders and fanning the eggs with his pectoral fins. Hatching occurs after 4-6 days .
