Reef Safe Aquarium Fish - Gobies

Gobies in the Reef Aquarium

General description: Gobies are one of the largest families of fish and, depending on the species, may grow to be under 1cm or over 1ft in length. They tend to have very long, brightly colored bodies, making them an attractive addition to any aquarium.

Living conditions: Gobies tend to stay toward the lower portion of aquariums and require plenty of hiding spots within rockwork and coral displays. Some species are diggers and need to be provided at least two inches of substrate to burrow in. Some species will form symbiotic relationships with burrowing shrimps. The shrimp will maintain the burrow where both the shrimp and goby will live. In turn, the goby will alarm the shrimp if danger is near (these gobies are often referred to as watchmen). Gobies live peacefully in community tanks; just make sure the tank has a cover or canopy because some gobies like to jump. Tank size requirements depend on the type of goby – some require at least 10 gallons while others require at least 55 gallons, so be sure to do your research.

Feeding: Most gobies will diet on a variety of fresh or frozen shrimp, prepared food for carnivores, prepared food for herbivores, and algae naturally growing in the aquarium. Gobies tend to have very small mouths, so be sure that offered food is chopped or shaved into consumable sizes.
