Anyone have snails growing in their tank?

[Fish]

Hello all,

When I had my 90gal, I used to have snails that would lay eggs on the glass. I don't know what kind of snail they were but does anyone have these? I would love to find another source to buy mantis food from rather than having to depend on LFS shipments all the time. I only feed Ike live food once or twice a month. Thanks!
