Heh I think they're called Sang Yu (C. argus)...not sure about giants though. Most people don't realize that the fancy SH's are related to the edible ones (or if they do, the chinese names don't have anything in common...) C. bleheri is Chut Choi Deen Long (7 colored electric dragon) but not sure on giant SH's...
^ we'll see... i didn't buy any channa argus since i found micropeltes in the pet market... because of the severe power outage i had to leave the fish in the store, im getting them delivered tonight. i'll snap some iphone pictures when i get them
