Possible snail?

Discovered several of these on my rocks which i think are some type of snail. Had a couple of frags one one side of the tank die the past couple of weeks so I’m not sure if this may be related. Any thoughts?

Looks like some sort of star snail. Not sure if all of these are on the friend list, but someone will come along with more knowledge than me.

I've seen them sold as Ninja Stars. They're good snails from what I've experienced.

They're in the Astrea Snails family. I believe these guys main problem is they can't flip themselves.
