Are there predators among bacteria? If so, which ones?

Basically, bacteria feed on the elements around themselves or produce the necessary substances on their own. But there are bacteria that attack and feed on other bacteria. These are predatory bacteria. They cannot independently produce vital substances. They take them from other organisms. They live mainly in bodies of water or soil. For example, Vampirococcus lives in water bodies. It kills other bacteria by sucking out all the liquid from them, attaching to them due to its special structure.
