Unique Hippo Tang in School Aquarium

[CzarQwerty]

For the last 2 years, the hippo tang at Walnut Street looked like a regular hippo tang. Suddenly over the last few weeks, the fish has changed to look like the attached pictures. Very interesting and unique. I looked it up and this does happen to some hippo tangs. Just wanted to pass it along in case anyone else has experienced this.
Sorry for the poor picture quality. Was taken with a cell phone. I plan to go back with a real camera and will add those pictures to this thread.

I seen that the other day when I was in there and was going to mention it, but forgot completely about it.
