Description:

Gobiids are primarily fish of shallow marine habitats, including tide pools, coral reefs, and sea grass meadows; they are also very numerous in brackish water and estuarine habitats, including the lower reaches of rivers, mangrove swamps, and salt marshes. A few gobiid species are also fully adapted to freshwater environments. Most gobies feed on small invertebrates, although some of the larger species eat other fish, and a few eat planktonic algae. Gobiids maintain their burrows by fanning away sand inside the burrows. Furthermore, gobies use coral rubble to block burrow entrance. A single goby carry as many as nine pieces of coral rubble per minute. Gobiids also build a 6–13 cm high mound over the entrance of their spawning burrow.
