Yesterday I got a tiger nerite snail from Petco and put it in my betta's tank. Today when I got home from school I saw these all over the tank. What are they?

They are not on the snails shell.

I dont see anything in the second picture, but what I am seeing in the first I am going to say that it is the snails poop.

I think I see white spots, which would be nerite eggs. The babies will not live in freshwater. You can try manual removal of the eggs if you don't like the look of them.
