This name is most commonly used for the platinum version of Channa Argus.
You can look up any of the info you can find in the guide you've read regarding argus, it all works.
Argus has that one trick though, depending on collecting point, you'll have a fish that is more or less tolerant of colder/warmer waters.
Generally speaking, russian caught have a colder summer/winter routine, while south china ones are a warmer version.
This is from the top of my head, you may want to follow the vast amount of guides on the internet about them, you'll find plenty knowledge. The fact they are platinum is a visual bonus, it does not affect the fish needs.
