San Ignacio is a quaint town in Belize near the border with Guatemala. It’s a popular hangout for travelers visiting Mayan sites or caves in western Belize. It’s also an easy place from which to visit Tikal (one of the most impressive Mayan sites, which is located in Guatemala.)
This was taken with a cheap underwater camera while snorkeling off Ambergris Caye in Belize. The fish align themselves in the shadows of boats. The water is shallow there, and so the sun blazes off the white sand on the bottom. The fish apparently have a hard time getting fishtan lotion, and need to take advantage of any shadow they can get.
