The picture you’ve seen here is not a silhouette or created by Photoshop, but it is a real portrait of an aberrant version of Magnificent Foxface (Siganus magnificus) that is only black and white. The normal coloration of this species is painted with red dorsal fin, yellowish tail and anal fin. It is one of the 44 pieces that turn out to be very special.
However, this individual is lacking the red and yellow; this may be a similar case to the white ‘Casper’ Yellow Tang as it is not the albino version of an animal but just a rare abnormalities. Normally, the fish that being sold in the world market is exported from Sumatra as it is restricted to Andaman Sea. But this individual was caught from western coast of Thailand and is now being exhibited in the show tank of Blue Space Marine Aquarium Shop in Thailand.
