Sorry I meant the second set of photos look like T putitoria but were posted by you afterwards else - the small fish that you describe as very rare golden mahseer !!!!.
I disagree with your Id's -
the first pic you posted look like Neolissochilus - i'd guesss sp hexagonolepis looking at the head shape, scalation, dark lateral stripe, fins size, position and colour. - blue kelah are Tor Douronensis - which are fairly widespread throughout Thailand, vietnam and the mekong system - therefore would never be found in India - N hexagonolepis - ARE however found widely distributed and I have checked to find them distributed throughout the himalaya. I have some and one does exhibit slight blue in the fins - Blue kelah is a completely different fish.
The second photo you have posted could be Tor tambroides or T tambra - if indeed from Malaysia - they could be another neolissochilus species though !
The third photo posted in this thread looks like T putitoria and are the fish you posted as golden mahseer - 1" long - that said they could be progenious - depends on locality?
What are the other fish in your second photo - the one head on to the camera ?
