Cryptocentrus cinctus
Common name: Yellow Watchman Goby. It should be noted that these fish are not always yellow. These fish often pair up with a pistol shrimp, serving as a lookout. They are relatively secretive, staying near a hiding spot at most times. Mine eats anything that falls near him. C. cinctus are reef-safe, but are known to fight with others of their own kind.
