You've got clams? Astera Starfish? Poorly photography skills? So many questions, so little details.

Sorry I do not have a regular camera just what I have on my phone. My clam closed up for the night like it always does but noticed these little snails and Astera starfish on it. I've seen them on the glass but never on it.

On the far right is a vermatid snail, that is the only thing I would remove because they create the mucus web that might bother the clam some.

all harmless, i had some tube worms on one of mine that made it look like it had thorns
