Dear Student,
The interaction between sea anemone and clown fishes is Mutualism.
Sea anemones are attached to rocks in their aquatic habitats and catch prey by stunning them with their poisonous tentacles. Clownfish are immune to the anemone's poison and actually live within its tentacles. Clownfish clean the anemone's tentacles keeping them free from parasites. They also act as bait by luring fish and other prey within striking distance of the anemone. The sea anemone provides protection for the clownfish as potential predators stay away from its stinging tentacles.
