100% sure its not a red aro, looking at the pictures its a highback not xback as its colour only starts to show abit on the fifth row not the sixth and no pearl
scales on the base of dorsal fins. Are you sure its not a red tailed golden
arowana?
Very nice Aro, and the pictures are actually pretty good for a camera phone, next time when you take pictures of your Aro, you can make the fish more clear in the pictures by following the Aro's speed with the camera and take the picture while you are moving with the fish.
