I don’t think that it is one. But it sure reminds me of tuna. At least this guy is sleek and built for speed as opposed to the puffer fish, who looks an ungainly truck. I’m running auto white balance, using on camera flash with a diffuser, and in macro setting. You get your share of misses. But when you hit, it’s pretty special. Thank goodness for digital. You shoot several hundred images to get 10 or 20 to keep.
