Fin's Fish Guide
The Citron goby (Gobiodon citrinus) is a saltwater fish of the family Gobiidae that grows up to 7 cm.
Description
The citron coral goby is a small goby (Gobiidae) from the Indo-Pacific. The species grows to only a few centimetres and has a stocky, yellowish body with blue-white lines on the head. It lives as a commensal among the branches of broadly branched Acropora corals, in which it shelters and lays its eggs. It feeds on small zooplankton and small invertebrates. For defence it secretes toxic skin mucus that deters predators; to humans the species is harmless, as it is not eaten and does not bite.
