Looking great Larry. I can see the darker tones starting to emerge. One year down, another couple to go!
As you know, you have to be very patient with Red Arowana as they don't show their full colour till they hit sexual maturity at around 3-4 years of age. Some people lose patience and go the tanning route; you can also use NAN lights if you want to enhance the red effect immediately. Otherwise, just keep on doing what you are doing and you will be rewarded with a very RED arowana in another couple years. Your fish has perfect finnage and symmetry, perfect jawline too.
