Barnacles??

Hey all,
The tank is finally set up and we did a good cleaning of the tank but a few of these guys are left… are they dangerous to the tank? Look like barnacles or some sort of muscle?

Not limpets, they don’t move and their shell isn’t conical. Wish I could get a better picture but they are in the back of the tank and I didn’t take a pic when it was empty ‍

Definitely looks like keyhole limpets.

Looks conical to me, I even see the snail heads on some of them. And they are grazing on a patch of algae back there.

They don’t move. But whatever they are the Elmer as crab is going ham on them

I would agree it's limpets
