The number of fish species in Bangladesh remains an unresolved inquiry. Rahman et al. (2005) report a total of 265 freshwater species, while Hossain et al. (2012) identify 293 species. Our recent analysis and published paper PLoS One 20(4): e0318982 https://doi.org/10.1371/ journal.pone.0318982 identified seven potential new species in this emerging country that necessitate further exploration to evaluate the hypothesis. Additional study is necessary to safeguard the precious freshwater species in Bangladesh.
