Snail on clams

[Paoworld01]

Hi, I’ve had this clam for several months now and just recently noticed a bunch of these snails on my clam when the lights are off. Seems to only be on the clam and nowhere else, I can see maybe 8-10 of them. Clam is healthy and is growing really good. I’m sure they aren’t pyramid snails. Should I be worried?
