What could a brown or tan or gray spot on the rear half of one side of an orchid dottyback be? I haven't been able to get a clear view of what's on him, he's in his cave most of the time, that's why I'm unsure of the color of the spot. The spot is probably 1/8 inch in diameter, maybe bit bigger. I haven't found any common problems that indicate a symptom of this kind. Otherwise he's eating fine, out as much as usual and no other fish are showing anything like it.
