What are you looking at?, Part 3

Nothing to see here, just a rock and some coral. Move along. There is not a fish here, especially a lawn mower blenny. Nothing to see, got that?

This is Larry, the lawn mower blenny hiding in the rocks. Unless you know what to look for and manage to isolate him against a solid background he is practically invisible. He eats algae, frequently leaving kiss marks on the aquarium glass. He also hunts the little white specs that can be seen floating in the picture. They are isopods, or tiny little bugs.
