Cephalopholis cyanostigma
@Marta,
Coloration and the shape of the fins doesn't work for Cephalopolis minata.
It could be Cephalopolis argus but the stripe pattern does not look a match. I think is miniata. Do you remember if it was reddish?
BTW, nice cleaning station with client (the grouper) being groomed :-)
