I had a really hard time capturing an image I liked of the seahorses. They don't move a whole lot but there was a good current in the tank and they blend in with their surroundings. Just as we were moving on I looked back again and saw this seahorse pretty much out in the open and took a shot before the current took it away.
During this visit I was using my new Olympus PEN E-P3 camera. Photo settings were:
f/3.5, 1/60 sec., ISO 1600, no flash
