Unfortunately, I don't have a pic, and it's not a red coris, but thanks for your suggestion! The body was light, almost white, in fact. I've emailed the science center, but so far I've received no reply.
I'm trying to determine what type of fish I saw at the science center. It looked like it had eyeliner drawn in swirls on its face, and it appeared to have 2 small teeth (upper)-also spent a lot of time flinging sand around in the bottom of the aquarium. Any help would be greatly appreciated...
