overview
The Panda Clown Goby is usually found among the branches of pocillopora coral colonies. They are a small stocky shaped fish with a very large head for their size. There are many different color variations of clown gobies, and this species is black, white and yellow. They 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. However, they may nip at the polyps of SPS corals.
It requires a 10 gallon or larger aquarium with at least one pocillopora coral and some shaded areas for the fish to hide. 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.
It is common for clown gobies to spawn in an aquarium. Caution should be exercised if the aquarium contains Acropora sp. 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.
The Panda Clown Goby's diet should consist of a variety of brine shrimp, frozen mysis shrimp, table shrimp, and frozen food preparations for carnivores.
Approximate Purchase Size: 1/2" to 3/4"
