Watch one long enough and it will change color in front of you.
Groupers repaint themselves in seconds. Pigment cells in the skin are pulled tight or spread wide under nerve control, and a fish that was plain orange goes blotched, or pale, or throws a set of dark bars across itself, faster than you can change a camera setting. They do it for camouflage against a new background, and they do it as signaling: a courting male, a fish defending a hole and a fish being cleaned all wear different patterns, and the pattern changes as the situation does.
It makes identification harder than the books admit. The same individual can look like two species over the course of a dive, which is why field marks that survive the change - the shape of the tail, the number and placement of spots, the size - are worth more than a general impression of color.
This one is a small hind, orange to orange-red with only a few blue spots scattered over the upper body, and it lives in the 🌊 Red Sea and nowhere else. It sits deeper than most of its relatives, generally below fifteen meters.
