since it came from India, it may not be Java Medaka (Oryzias javanicus) but possibly Oryzias dancena which is from India.
The one I posted looks slightly different from yours (no colour fringe on the anal fin) so perhaps mine is the javanicus instead. I don't remember asking the LFS where the fish came from, but then again the suppliers to LFS don't always give the right info. E.g. the LFS was told a particular barb came from Africa but in fact is the Rasbora vulcanus from West Sumatra.
Here's the one I got.
