The Watchman Goby is a tiny reef guardian with a big job and an even bigger personality! These small fish usually grow to just 2 to 4 inches long, but they’re full of charm. Their bodies can be yellow, tan, gray, or even speckled with bright blue or orange spots, depending on the species. One of their most adorable features is their big, expressive eyes—always on the lookout, which is how they got their name. Despite their small size, they’re incredibly alert and known for forming some of the ocean’s coolest partnerships.
