What is the name of small round pasta balls?

Other options, depending on size, could include:

* Acini di pepe: Very small, almost like couscous, and often used in soups or salads.

* Anellini: Small, ring-shaped pasta.

* Penne rigate: The "small" version of penne, but still much larger than orzo.

Can you tell me more about the pasta balls you're thinking of? Are they very small, or more like the size of a pea? This will help me pinpoint the name!
