Green Clown Goby - Gobiodon atrangulatus The Green Clown Goby, also known as the Earspot Coral Goby is common within the reefs of the Indo Pacific, found usually among soft and hard coral colonies. They are a small stocky shaped fish with a very large head for their size. There are many different color variations, and this species is a yellow to greenish-tan color with orange vertical stripes on its head. The Green Clown Goby are a peaceful fish that makes a wonderful addition to a reef aquarium containing colonies of polyp corals, as they enjoy swimming and hiding amongst the polyps. The Green Clown Goby are perfect fish for any sized reef especially nanos because they stay nice and small. They do not swim much around the tank but instead look for a spot to perch and watch what's going on. The Green Clown Goby will often perch among the branches of SPS corals but can decide to rest on other types as well. They rarely do any real harm to the corals. They can be tough to feed but only because of the size of their mouths. The Green Clown Goby will readily accept any type of marine foods you offer as long as they are small enough to get down. In very small tanks they can possibly be aggressive towards other clown gobies, but some will pair up. Habitat:
The Green Clown Gobies are found in Indo-Pacific Ocean. Minimum Tank Size Suggested:
The Green Clown Goby requires a 30 gallon or larger aquarium preferably with branching coral. It will rarely become aggressive towards other fish, but will fight with its own kind in smaller tanks. Therefore, it is best if it is kept with other docile species. The Green Clown Goby grows up to 1.5 inches. These fish generally will come to you 1 - 2.5 inches. Tank Conditions:
The Green Clown Goby is a low maintenance fish. They normally require good water condions like temperature ranging between 72 and 78 degree Fahrenheit. This temperature is suited perfect for the Green Clown Goby in aquarium. The specific gravity lying between 1.020 and 1.025, like other saltwater fishes, is required for them and the pH should range from 8.1 to 8.4 points. Feeding and Diet:
The diet of the Green Clown Goby should consist of a variety of brine shrimp, frozen mysid shrimp, table shrimp, and frozen food preparations for carnivores. If housed in a reef tank with live branching corals, it needs to be fed once a day. If housed in a tank without substrate, it will require several feedings per day. Breeding:
The Green Clown Goby are known to successfully spawn in an aquarium, laying eggs that sink into the coral branches where they are protected. The Green Clown Goby should be housed as a single specimen or as a mated pair, unless they are kept in a larger tank where a small group can be housed, and should be with other peaceful species. Like the Yellow Clown Goby, the Green Clown goby is a peaceful addition to any reef with caution. Normally found living among soft and hard coral colonies, the Green Clown Goby make their nests by tearing the covering off acropora colonies. Luckily they rarely cause much damage but if you only have one small acropora species you might want to rethink this fish. It is common for he Green Clown Goby to spawn in an aquarium but the caution should be exercised if the aquarium contains Acropora species or similar SPS corals. They will lay their eggs on the underside of the coral's branch, which will cause tissue recession in that area of the coral. However, under good conditions, the coral will regenerate the lost tissue.
