Biology     Glossary (e.g. epibenthic)

Found in estuaries, but can live temporarily in freshwater. Inhabits quiet rocks and corners of creeks and backwaters. Can withstand a wide range of salinity varying from 4.36 to 1.35% (Ref. 48443). Breeds easily throughout the year peak period during July and August. Larvicidal fish and eats mosquito larvae at the early instar stages. A suitable fish in malaria infected areas (Ref. 48443).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Barbed sperm bundles or spermatophores are passed from male to female. Fertilized eggs are then laid one-by-one or en masse over a relatively large area rather than in one location (Ref. 80012).
