What Does This Mean, snails?

I have snails (mostly MTS) in my two tanks and have observed interesting behaviors. From time to time, sometimes after water changes, I see my snails out on the glass by masses. What does this mean when the snails are out of the substrate and on the glass? Does this have something to do with the water quality? Can this possibly mean lack of O2 in the water or any other water issues? Just wondering ...

In your case, I would suggest testing your aquarium water just to be safe.
I would also test your tap water. IME snails will come out of hiding 1) at night to forage, 2) when they don't like the conditions, and they are trying to find a better place.
