I look forward to seeing photos of your fish Earl, especially the "gold head" banjar. I've been told by aro farm owners that GH mutations can occur with almost any species of aros, from RTG to XB; I'd be surprised to see it happen with a banjar, but then a mutation is a mutation.
For old time sake I am posting a couple photos from the arrival of the fish at the airport. The fish in the bag is your SR Earl.
One of our fourm members set up a 9 SR com tank out of this order, would love to see some photos of that set up...
