The typical gobby is a small, tube-shaped fish, perhaps about 5-10cm (2-4in) long and often drably colored. It spends most of its life scurrying along the sand. Many gobbies live in small caves or among coral branches and many enjoy a symbiotic relationship with other animals, most notably with certain species of shrimps. Since most gobbies are very hardy and disease-resistant and never cause compatibility problems, the small percentage of brightly species make excellent aquarium inhabitants. They are generally easy to feed on a wide range of readily available foods, including meat foods, dried foods and brine shrimps. These fascinating little fishes are widely available at dealers and not expensive.The very popular white fire fish is a burrowing fish imported in large numbers. The equally popular golden-headed sleepier (Helotries striates) is a gorgeously marked fish, with more subtle coloration than most marine fishes. It lives in a self-made tunnel it’s the sand, maintaining an early vertical position, with just its head poking out. These fishes have typically large eyes set high up on their blunt snouts.
