Are you sure it is from India? Fishbase.org only lists 8 nandidae in India, 4 badis types(not them, I checked all but the Badis kanbos which I can't find a pic for), The Dario dario (nope), 2 pristolepis (not them either) and the Nandus nandus, here is a pic.
I also found one the did not list, the Badis bengalensis but that is a typical badis.
the fins, head, mouth, foreheadstripe, and eyes are right for the nandus but yours is an odd coloration. Could yours be leucistic? It even shows a hint of the spot just before the tail base.
Do I get to post a pic?
