The Bar Goby a peaceful fish is a member of the family Microdesmidae, which are referred to as dartfishes, close relatives of the popular Firefish. It is light green with pink bars on the body, a pink blotch on the gill cover and blue lines on the head. The bar goby should be kept with less aggressive tankmates in an aquarium with numerous places to hide. The Bar Goby is often reluctant to come out of hiding for a week or two, but once it is fully acclimated it will swim about the tank without reservation. These gobies are rarely aggressive towards other fishes, and can be kept in small groups in the aquarium.

The Bar Goby is a peaceful little fish that can make a good addition to a great variety of marine aquariums. Once you have seen the Bar Goby, it will be quite easy to understand it is a favorite fish among many marine enthusiasts.

The Bar Gobies get along well in groups or pairs, and act peacefully when combined with other species. If the group of Bar Gobies is to be kept, they should be introduced simultaneously. The Bar Gobies are considered to be ideal for reef tanks, and many are also kept in peaceful fish-only aquariums. They should be provided with a soft or sandy patch of substrate or rubble into which they can burrow. They also prefer some sort of current present in their aquarium. Over the elongated body are a number of vertical bars. These are orange to pink in shade, and each is edged in a bluish to purple hue. The rest of the fish is a pale green to silver color. Both the head and body of the Bar Goby are light green. Its attractive slender body has numerous vertical, evenly-spaced thin orange stripes displaying an intricate pattern.

The Bar Goby can be shy in the beginning and eventually come out and be friendly. All over metallic green body with contrasting colored stripes makes this timid but beautiful dither fish an excellent choice for a reef

Maximum Size: The Bar Goby usually grows to about four inches (ten centimeters) long at maturity.

Minimum Tank Size Suggested: A 20 gallon aquarium is appropriate for a pair of Bar Gobies.

Tank Conditions: The temperature between 75 and 78 degrees Fahrenheit and a pH value of 8.3 or 8.4 are appropriate for Bar Gobies. The specific gravity should remain between 1.020 and 1.025. For a fish-only enclosure, values between 1.020 and 1.023 are appropriate. However, invertebrates require higher specific gravities. In an aquarium with these animals, the appropriate specific gravity would fall between 1.023 and 1.025. Plenty of hiding places, and a soft sandy substrate should be provided for Bar Gobies. The Bar Gobies should be kept in pairs or groups and generally get along well with other fish, which they will clean.

Habitat: The Bar gobies are found in Indo-Pacific Ocean from Red Sea and islands in the western Indian Ocean to the Line and Marquesan Islands, north to the Ryukyu Islands, south to the southern Great Barrier Reef; Mariana and Marshall Islands in Micronesia.

Feeding and Diet: Bar Gobies should be offered foods small enough to fit in their mouths. Often, mysis shrimp or brine shrimp are appropriate food for them. Care should be taken to prevent this fish from jumping out of the aquarium as they have been known to do.

The meaty diet of the Bar Goby should include fresh or frozen seafood and brine and mysid shrimp. The Bar Goby is a low maintenance fish.
