Did you mean Red Tail Gold Arowana? If so the anal fin and caudal fin should be orange-red only. Since you said the anal fin and dorsal fin,tail(not sure if you mean caudal fin or not) is orange color. It could be a Red Arowana-Super Red/Chilli Red/Blood Red/etc or a Banjar Red(hybrid of Green and Red Arowana). Hope this helps a bit.
