The chromatophores of these fishes were micrographed utilizing the camera through the compound microscope's eye piece under 10X magnification. Three selected species of fishes were Aspidoparia morar, Channa punctatus and Mystus seenghala. The most abundant chromatophores were observed in the body region of C. punctatus. The least number of chromatophores were in caudal region of A. morar. A. morar showed the greatest number of chromatophores in the body region and least number of chromatophores in the caudal region. C. punctatus showed abundant chromatophores in body region followed by the fin region whereas least number of chromatophores was present in the caudal region. M. seenghala showed a greater number of chromatophores in fin region as compared to body.
