What eats colpidium?

Colpidium, a genus of ciliated protozoa, is primarily consumed by various microorganisms and small aquatic creatures. They are often preyed upon by larger protists, such as certain species of ciliates and flagellates, as well as by small metazoans like rotifers. Additionally, some larger filter-feeding organisms may also ingest Colpidium as part of their diet.
