I'll get a pic, but I think you guys can figure it out without a pic. It's a common Tang, I've seen it lots before, but I can't find a pic, and I'm no good with Tangs!!
It's only about 1.5-1.75" including the tail. Body is brownish greyish with light colored lines all over it. Yellow tail and yellow circle around the eyes. Like an adult Kole tang, but with a yellow tail. Maybe it's a juvenile Kole? I dunno. It was sold to me as a Mimic, but I don't think that's right...?
