tiny white spots that feel hard like a rock. They appear to be spreading around the tank. I was told they are a type of tiny snail that does not move. Any thoughts on this, anything to worry about ? thanks

They appear more as white dots which are hard to the touch unless the photo is highly magnified. Don't know where they came from as no new rock has been added in a few years. Anything that eats them that I could add to the tank ?This is a fish only with live rock tank with big angels etc thanks

Spirorbids or pileoralia. Either way, harmless little filter feeders. If they are unsightly to you just scrape them off. They will, however, continue to grow.
