Engineer Gobies, a.k.a. Convict Blennies, are in a family all by themselves. These fish are usually found as juveniles and have an elongated eel-like body. They are black with a white horizontal stripe running from eye to tail. In the wild they form huge schools over sandy bottoms. They can be kept in groups and like to burrow under rockwork.Gobies compose one of the largest family of fish in the ocean. These small fish live around reefs or on sandy flats. Many of the Gobies are known for their burrowing behavior. These fish use burrows in the sand for safety. Some of the Goby species are known to share their burrows with Pistol Shrimp; behavior that can be duplicated in the home aquarium. Most Gobies have cupped ventral fins that nearly join just below their gill plates that serve as perching mechanisms so the Goby can always be on the lookout in a resting position. The Goby is a tremendous addition to the home aquarium.Photo by saltwaterfish.com member larrynews
