All in a Name
The Okinawa Goby has the scientific name Gobiodon okinawae. The Okinawa Goby is also called the yellow clown goby and yellow coral goby. The Okinawa Goby is part of the Gobiidae or Goby family. The species was identified by R. Arai, T. Abe and Sawada in 1972.
This is a small bright yellow fish, though it has a white patch on each cheek. The Okinawa Goby have seven dorsal spines and ten or eleven dorsal soft rays. The Okinawa Goby have one anal spine and nine anal soft rays. Their maximum size is one and a half inches. Any Okinawa Goby that size is male. Those that switch to female and stay that way regularly stop growing at an inch long.
Their bodies are covered in a poisonous mucus to deter predators.
These Okinawa Goby fish start life as females, but they can change gender throughout their lives. When two of them are paired up, the larger one becomes male. The smaller one in an introduced pair will become female, unless the larger one is already female.
These Okinawa Goby fish are not burrowers like most gobies. Instead, they prefer to reside in the branches of staghorn coral. The Okinawa Goby are reef safe, though they will nip at SPS corals.
The Okinawa Goby can be kept in tanks as small as ten gallons. If you want more than one, a thirty gallon aquarium is better. If the tank does not have corral then you need to have more hiding places than fish that want to hide in them.
