- Species Information
- Scientific Name:Gobiodon citrinus
- Described:Citron Goby
- Maximum Size:2.5 inches
With its bright yellow body and blue markings, compatibility with other fish, and an appealing personality, the Citron Goby, Gobiodon citrinus (Ruppell, 1838) is an excellent addition to most reef, fish only with live rock (FOWLR) aquariums, or even nano aquariums. These charmers are naturally found perched amongst the branches of Acropora corals, awaiting their next meal.
Physical Description– Small, deep yellow to brownish-yellow body with bright blue lines running vertically around their eyes and gills, and horizontally along their dorsal and anal fins.
Temperament– The Citron Goby is generally peaceful, though it may fight with other gobies if kept in a small aquarium.
Size– Maximum length is approximately 2.5 inches.
Diet– The Citron Goby is carnivorous and will readily accept frozen brine shrimp, mysis shrimp, and other meaty prepared foods, so long as the food can fit into its mouth. Spot feeding is suggested, if possible, to ensure enough food reaches them. Over time, these gobies have been known to eat right out of the owner’s hand.
Distribution– Western Indo-Pacific Ocean, from southern Japan down to the Great Barrier Reef, and from the African coast to the west, to Somoa in the east.
Interesting Fact– Also known as the “poison goby”, the Citron Goby is covered with a “toxic slime” that deters other fish from bothering it.
