Didn't know snails got this large

Have had this set of snails since I started tank after cycle in February. Does it seem oversized? Should I be worried about size and disruption to tank i.e. rock work, moving corals other invertebrates or fish?

I have seen Turbos get to the size of a softball, they can be bulldozers but other than that cause little harm.
