The Neon Goby is a slender Goby that has an electric blue body stripe that runs from the front of each eye to the base of its tail. The upper body of this fish is usually darker with a pale underside. These fish serve as cleaners in the wild and will setup a cleaning station at reefs where fish come to be cleaned of parasites. They spend most of their day clinging and perching on rockwork or aquarium glass. They are very peaceful and make great additions to any peaceful tank. The Neon Gobies serve as cleaners to larger fish.
