I took this photo while diving off the Sunabe Seawall in Okinawa, Japan (East China Sea). It was moving fast for my novice 6mp camera and skill.
It looks like I fish I used to see on Guam called the Spotted Sweetlips, Plectorhinchus picus. I have a Micronesian fish book that says they can also be found around south Japan.
You can find it in the REEF FISH IDENTIFICATION Tropical Pacific book. Pretty sure it's the Many-spotted Sweetlips Plectorhinchus chaetodonoides, rather than the spotted aka dotted sweetlips P. picus.
The fish id has been pretty good so far. Indeed, that will be the thing that makes it better. - Flemings Ultimate Garage
