i ran across this asian in someone's business. he said it was a malaysian yellow. it does have yellowing at the edges of the fins also the back of the fish is very dark in color also there is a red coloring at the base of fins on the body
could also be a yellow tail or banjar red which are a hybrid of a green and red arowana.. if you could get a shot of the whole body it would be easier to identify
but from that shot its does look like a green though..
