That white one, Auranti, that you showed after the black finned one really looks like an " immature" white pearl lemmon ( as divulged by Glaser in Germany )
Would you take a look on their site ( look for Channa sp white pearl lemon , please )
They give no info whatsoever on the beast, in one place saying it is Striata complex in another Argus complex.
I ordered a trio and would love to know more.

PS - just now read that you say they grow huge...( glaser states they get to 40 or 90 centimetres )...how lost can one be?
I read the info on the website and it was pretty interesting. I that picture stated in the aquarium glaser website
. I'm no expert but i'm going with C argus complex. I dont think its a C striata mainly because those guys are broader, I could be wrong however. If it is an argus, it truly will grow into a monster. I have a pic of a huge one (40/50cm?).

The pic above is taken at a fish shop, they had 2 but one was sold away.
-EDIT-
You stated that mine looked like an immature 'white pearl', is there a photo of the adult 'white pearl' online?
As for the black finned 'platinum', I do believe the black finned platinum i have currently is the same 'species'.
Side by side comparison
This is truly an intriguing fish, takes the market by a storm and not much info is known about it.
I wish you the best of luck with your trio
