While examining the gut contents of these fishes, it was found that <em>C. gachua</em> fed primarily on insects, <em>G. annandelei</em> fed mainly on filamentous algae whereas <em>H. fossilis</em> fed both on plants and animals. Their brain morphology revealed that olfaction in <em>C. gachua</em> was stronger than in <em>G. annandelei</em> and <em>H. fossilis</em>. Similarly, optic sense was also more powerful in <em>C. gachua</em> than in <em>G. annandelei</em> and in <em>H. fossilis</em>. On the contrary, cerebellum of <em>H. fossilis</em> was more developed than that of <em>G. annandelei</em> and <em>C. gachua</em>. These morphological differences of brain could be undoubtedly correlated with the carnivorous, herbivorous and omnivorous feeding behaviour of <em>C. gachua</em>, <em>G. annandelei</em> and <em>H. fossilis</em> respectively. Moreover, in all three fishes, around 20% of the total gut content was made of mud and sand, and they all had inferior mouths, indicating that they were bottom feeders.</p><p>Int J Appl Sci Biotechnol, Vol 4(1): 79-81 </p>}, number={1}, journal={International Journal of Applied Sciences and Biotechnology}, author={Shrestha, Rajani and vaidya, sheetal}, year={2016}, month={Mar.}, pages={79–81} }
