These were actually taken last week. As I was filing my RAW images I saw that I forgot to process these. I think they are probably three of the best that I've taken of this fish. For this I used only one key light offset to the right of the fish. I used a reflector on the bottom of the tank and bounced light up from the bottom...slightly illuminating the fish. I think the overall effect is more dramatic.
. Do Zonatums all get the large bulge under the throat like this one has?
