I recently had one of those snails hitchhike on a plant I bought then a week later, I saw a bunch of those eggs in that slime which I removed. That didn’t stop more from developing. First, as small transparent dots on my glass, and then developing into adults. On an Aquarium Co-op video, Cory talks about snails. He’s of the opinion to leave them. Yes, their population will grow, but only to the extent that there’s enough for them to eat and survive. It you develop a serious population explosion, that’s a sign that either you need to do maintenance and gravel cleaning or are over feeding your fish. They are a good barometer of your tank’s health. Otherwise, they are helping clean up your tank. I’m keeping an eye on mine and so far, all seems well. Their presence keeps me on my toes!
