Gobies do not confused them with Blennies!

There are over 2,000 species of Gobies, the most of any marine fish family. These cute little fish have long, slender bodies, and big eyes located on the top of their large heads.They are sometimes confused with Blennies but Gobies have two separate dorsal fins while Blennies have only one long one.
Some species can be quite colorful while others are drabber and covered with spots and stripes to blend in with their surroundings.

Gobies feed on a variety of things including algae, plankton, and small invertebrates. When full grown they range in size from the tiny (less than ½ inch) to the extra large (18 inches), but most will grow to a length of 4 inches or so.

Many Gobies lead fascinating lives. For instance, some species form a symbiotic relationship with shrimps. The Goby lives in the shrimp’s burrow and in exchange for a home it warns the blind shrimp whenever danger approaches. Others, such as the Neon goby, serve as cleaner fish. They feed on the parasites and other debris of larger fish that come to visit them for this “cleaning” service.

Gobies do best in an aquarium with a lot of rocks and crevices to hide in. These fish are jumpers so the tank should have a secure cover. They should be fed a good variety of fresh and prepared foods that consist of both protein and vegetable matter.

Gobies are peaceful fish and should be kept with other non-aggressive fish; they are a favorite snack of large fishes. Some species are quite territorial and only one member should be kept per tank while other types do best when kept in pairs or small groups.

Several types of Gobies have been successfully bred in captivity but it is by no means easy to accomplish. With many species it is difficult to distinguish between the sexes. After the eggs hatch, the fry go through a larval stage and require specialized food and care.
