The Wyoming White Clownfish has a uniform white coloration. Their fins are dark shortly after metamorphosis and turn jet black as the fish grows. Their orange face will develop a beautiful black outline as the fish mature. Some Wyoming White Clownfish have a black spot immediately behind the gill cover (see picture). To the untrained eye, it can sometimes be challenging to tell the difference between ocellaris clownfish and true percula clownfish. The giveaway is their eyes and the number of spines in their dorsal fins (see picture below). The iris of an ocellaris clownfish is typically pigmented with shades of black and grey whereas the iris of a true percula clownfish is typically a clear orange color.
