Good or bad snails??

I have these also. They seem to really come out at night. I haven't noticed any issues with coral and like someone else said, they appeared after adding turbos. I assumed they were babies.

I've got mini snails that look just like that in my tank, I've had them for years without issue. They appear to only eat algae so far. If I'm not mistaken I think I've sold you some frags in the past so they very well could have come from me.
