Is anemone a parasite of hermit crab?

Anemones and hermit crabs are an example of this type of relationship between living organisms, such as symbiosis. The hermit crab specifically settles this hydroid on its shell so that it protects it with its stinging cells, because it is quite easy for a predator to get crayfish from the shell for the sake of its soft abdomen. In addition, the cancer feeds on the leftovers from a scruffy sea anemone dinner. The polyp, on the other hand, travels in this way and increases the ability to catch something, since he leads a sedentary lifestyle and cannot move independently.
