In the saltwater section at Petco I saw the typical clowns and other fish. But then there was this odd looking fish that could dart around and stop on a dime. When he saw me he ran around behind this rock. His two eyes peaked out and looked at me, then from the other side of the rock, then he raced to this other prop and got inside, and kept moving to different holes to peek out at me. I read its name - Lawnmower Blenny. When my tank's ready for fish, this will no doubt be my first one!
