Wonderful addition to your freshwater setup, especially those with shrimp as these guys love to eat hydra. They'll also eat algae, biofilm and leftover food as well as the odd pest snail. Strongly recommend giving these guys something for shell maintenance and growth - I personally give cuttlefish bone and hide it behind decor.
Well worth having a Google search on them to read about their specific traits and needs. These are not mystery snails that lay eggs above water, these will lay clutches below the surface and are easy to spot. I believe they're more apple snail.
