Your pagoda snail aquarium should always be fully cycled, as this species is sensitive to low water quality. You'll have to perform weekly water changes to avoid nitrates from building up.
Another important factor in caring for aquatic snails is that you need to keep in mind the water can't be too soft or acidic. A very low pH can slowly dissolve the calcium in a snail's shell and cause damage in the long run. A lack of minerals like calcium, on the other hand, can make the snail incapable of producing a healthy shell at all. This is why even in a suitable tank, it's often recommended to feed a calcium supplement.
pH: 7-8

Tankmates
The pagoda snail gets along with most tankmates, as long as they favor similar water values and you don't combine the snails with carnivorous fish. Sure, they have their shell and operculum to protect themselves, but they're otherwise pretty defenseless when faced with an attacked like a hungry loach!
Aquatic snails like this one make a perfect choice to add a little extra life to a (dwarf) shrimp aquarium. Their peaceful and herbivorous nature mean they're among the only species that will leave even small and fragile baby shrimp alone.
