because for me the characteristics of these fish are a combination of genus tor and genus Neolissochilus , especially n starcheyi.
might be more obvious if you watch the video mr cmo9 on youtube(link is available at his last post).I also commented on the video..
pliss watch at timecode 0:12.
whether it is possible that fish, same kind as mine??

I don't believe that there's cross-breed hybrid of theses 2 genus.
I was told by the lfs where I got my 4 blue ones that these fish was imported from Thai, so I'm convince by chedra's opinion:
Neolissochilus spp. [tengahs] are widely distributed in streams and waterfalls in Southeast Asia. Unfortunately only the blue fin one from Chaophraya, Mekong and Maeklong drainages in Thailand are probably assigned to correct scientific name, Neolissochilus stracheyi... Other species may have been described already but without comparision with the original description and/or type specimens it is hard to know who is actually who...

I was told by other foreign hobbist that this fish is Nukta nukta, although it looks quite alike Bangana behri but I ain't sure whether they're the same. Btw, this fish had been given away 6 months ago because of it's bad temper.

Hard to see the mental lobe in youtube. Anyway Tor = mahseer = kelah = Pla vien has mental lobe at the middle of lower jaw. See this paper:

IIRC Tor douronensis has rather small mental lobe:

Neolissochilus stracheyi:

Note the absent of mental lobe. Maybe it should be called blue tengah instead?

Fix:

Thanks for the material!
Will try to take some decent photos of their lower jaw; of course not out of water. Also I finally see an adult Tor sinensis from the paper, it is stunning!

Here's an old pic of 1 of the three:

The snout isn't very obvious sharp so I can't really confirm the ID.
Maybe when it gets bigger and with sharper snout can confirm it as Neolissochilus subterraneus.

There's a latest pic on P.1.

That's a Neolissochilus subterraneus. The cousin of the Thai blue on my opinion.

Young subterraneus. Even when small their snout shape is rather point:
