It's a "variant" of Channa micropeltes. To sell better (higher price), just add "golden" to the name... so it's referred to as "golden channa micropeltes" by some people to differentiate it from the more common-look micropeltes. Can be found in Malaysia which the people refer to it as "toman emas" (toman = snakehead, emas = golden/gold. As they grow bigger, perhaps they will look more like the common ones <--- perhaps someone can confirm this??
Search for "toman emas" at Youtube to see some nice juveniles...
So this is the one they call golden?
As I said, it is called "golden Channa micropeltes" by those who are selling at higher price. It is not "golden snakehead". "Golden snakehead" is the common name for Channa stewartii. Names can be very misleading...
