I am Clownfish. While most small fish avoid sea anemones, I am perfectly at home among their stinging tentacles. A coating of mucus protects me from the anemone’s venom. I lay my eggs within the security of the anemone’s tentacles. In return for its safe home, I aggressively fight off other fish, often much larger than myself, which might try to nip off the anemone’s soft tentacles.
