Banjar Red have yellow fins, it looks like a green, never heard of a emerald merlion gold arrowana.
After googling emerald merlion gold, it seems that a banjar red could be known as a merlion. There seems to be 3 varieties of merlion, red, gold, and green. The banjar red looks closest to the gold, however, banjar seem to have a more blueish, pink hue to the scales.
I beleive they are all hybrids of green and rtg.
