We were running an underwater photography workshop in Raja Ampat, back in October, I don't know which was more difficult the 52 hours of travel time or finding a Pygmy Seahorse. lol I found this Pygmy Seahorse in about 50ft of water on a sea fan (interesting fact Pygmy's change color to match the sea fan they live on). Also this guy is about the size of your thumbnail, they are so tiny. I was shooting on a Nikon D810 with a Sigma 105mm macro, in a Ikelite housing with 2 Sea&Sea strobes. Settings: F22, 1/125th, iso 400
