Wesley Wong graciously transferred 4 of his mahseer to me in Aug 2015 - khudree, malabaricus (which may be another khudree), soro, and progenious. Tor progenious was probably ~18"-20" back then. It's done well in one of my 4500 gal tanks and reached roughly 22"-24". Pretty peaceful fish, at least I've not witnessed any aggression from it toward its very motley crew of tank mates.
To my eye, it is the prettiest mahseer in my humble collection (I too have a stracheyi and two unknown ones labeled enigmatically as Golden Thai mahseer). Not for the color, which looks platinum, but for the body structure.
Surprisingly, it prefers to keep away from the front window in sharp contrast to the other mahseer. So for now all I have is this "What's in the video?" kind of a vid (in a vague analogy to the popular "What's in the bag?" game). When / if I get a better video, I'll certainly post it here.
