Yes, It is form of a Chiton. I have one that looks exactly like yours. No harm. He pokes his head outa the rock once in a while, then goes back in. Never coming completely out. Never harming anything



Some info I found before

A Flexible Chiton (Cryptoplax larvaeformis) moves inside the reef to avoid the light on a coral reef near Mabul Island, Sabah in Borneo, Malaysia.
As the eight shell valves have been reduced in this long species (about 5"-6") long, it can appear to be more worm like than other Chiton species. They are normally nocturnal, though when seen during day light hours they generally rapidly retreat into the reef. Due to the reduced shell size which does not protect the whole body, they are also found away from wave action unlike other chiton species.
