Bottom of both photos. The lighter individual is obviously A. coeruleus, but the darker individual is less distinct. I identified it as such mainly because of the white spine on its tail, whereas A. bahianus and A. chirurgus have dark spines. Nevertheless, I am uncertain as to its positive identification.
