No, they aren't.
No, anemones are not parasites. They are predatory marine animals that belong to the phylum Cnidaria. Anemones capture prey using their tentacles and stinging cells, but they do not feed off other organisms in a parasitic relationship.
Many species of wentletrap sea snails attack sea anemones. Some species swallow small and juvenile sea anemones whole, while others apparently nibble on tentacles and tissues of large sea anemones. Many sea slugs that prey on sea anemones, such as the rainbow nudibranch, Dendronotus iris, do not kill their prey, but merely shear off a few tentacles with each attack.
