I know that you all aren’t as crazy about fish as I am, but I have to include this fellow simply because of his size. This pacu, which is a close relative of the piranha, was at least a foot and a half in diameter, and truly impressive when one swims right past you! Again you can see how crystal clear the water is, and if you don’t move around too much, how close the fish will swim by you. It was like swimming in a really big moving aquarium.
