I have many of these on my live rock what could they be

It moves right? Looks like a stomatella snail or a limpet. Both of which are beneficial

It may be a chiton then, either way it looks like one of the hard shelled crustaceans. Limpet or chiton is my guess

As long as it's all in the good I am ok with whatever it might be [emoji106][emoji16]
