Puntius jerdoni
A great schooling fish, peaceful and gets to 12" so more to show for than the roseline sharks, and hardier. This fish is rarely if ever offered here in the United States.
Not sure if I interpreted this wrong, but Tinfoil Barbs are the species Barbonymus schwanenfeldii, whereas those are called Jerdon's Carp.these fish are being sold at my local petsmart as tinfoil barbs
