Abstract

Croaking gourami Trichopsis vittata Cuvier, 1831 is a small tropical freshwater fish of the suborder Anabantoidea, family Osphronemidae. This fish is very popular in the aquarium fish trade in occidental countries because of its interesting behaviour and easy keeping. Male is slightly larger than female. This fish commonly inhabits shallow standing water with dense aquatic or floating vegetation. Additionally, croaking gourami can survive in poorly oxygenated water due to the existence of an air-breathing organ called a labyrinth. Both sexes produce a croaking sound by rapid pectoral fin beating during courting and fighting.
