This family is vast, with many shapes and sizes of species in its make-up. Like the blennies, gobies lack a swim bladder, and spend little of their time swimming off the bottom. The commensal life of some species sharing a burrow with almost blind Alpheid shrimps, is one of their more fascinating features. In the aquarium most gobies settle down well, to feed readily, making few special demands for their successful maintenance.
Neon Gobies (elacatinus oceanops) are found in areas of The Caribbean Sea, but many of those available to the hobby today are aquarium bred and raised. This is an attractive and hardy species, sometimes acting as a “cleaner” fish to other aquarium occupants.
The Firefish Goby (emateleotris magnifica) is a very popular aquarium fish, closely allied to the true gobies. The distinctive features of the species are its tail down, bobbing, swimming action, spiky elongated dorsal fin, and colour combination.
