this is a wild caught clown from Bali, and was imported by Hao Hoi Aquarium in hong kong. the fish currently lives with Dr. wing chung.
yes it's crazy from a genetic perspective how a clown can look like this. however if we take a look at it from another angle, and consider aberrations instead of genetic mutations. if centropyges and other reef fishes can have xanthic morphs that turn the whole fish yellow or koi coloured, why not clowns?
assuming this is a xanthic clown, it will be a matter of time before it changes its colour back to wild type. as we know, most xanthic fishes cannot keep their color in captivity. only time will tell. i regularly exchange with dr chung so i'll ask for an update in a few months.
however it could be a genetic thing. barless, colourless, extremely random mutation. what are the odds huh.
