  Trichopsis vittata (Cuvier 1831), a freshwater croaking gourami (Osphronemidae), typically regarded as a negative biological indicator, has been recorded from four different freshwater habitats in Bangladesh during the study period from December 2017 to August 2018. Taxonomic identification was confirmed from the external appearance, morphometric measurements and meristic counts of the species. The body was laterally elongated with clearly visible stripes and black blotch above the pectoral fin base. Average total length, standard length, pre-dorsal length, pelvic fin base length, dorsal fin base length, anal-fin base length, and pectoral-fin base length were 5.3 cm, 3.64 cm, 2.36 cm, 2.17 cm, 1.95 cm, 1.5 cm, and 1.0 cm. The number of rays in the dorsal fin, anal fin, pectoral fin, pelvic fin, and caudal fin were 7-10, 31-34, 9-11, 5-8 and 14-17. The occurrence of T. vittata in these rivers indicates their rapid spreading across the country within a very short period of time. Intensive research programs along with counter surveys are suggested to cross-check their spreading pattern, ecological sensitivity, and impacts on native fish biodiversity.
