Yes, a general name for any huge number of conical shaped small snails. There are local snails in ponds and rivers in the USA for example, which are pretty much the same. There are some with slightly differing shell colors and some with sharper ridges. MTS.
They generally live much of their time under the substrate. Often are out cleaning and finding snacks and cleaning up left over fish food.
If you ever see most all of them heading to the top of the tank on the glass, you have water issues and it is serious!
Over feeding allows them to multiply more quickly.
Personally I do not mind them, kinda fun to watch but having too many causes a poopy mess, not ideal in the aquarium.
