Clownfish defending its anemone from Leaf Scorpionfish

Clark's Clownfish are territorial and dependent on their host sea anemone which they use as a shelter for the group and a place to lay their eggs. Clark's Clownfish lay their eggs in batches on coral or rock next to the sea anemone they call home. The male, and sometimes the female, will guard and fan the eggs for 6-8 days until they hatch. Clownfish are all born males and the dominant male of a group will turn female when the female of that group dies. They can host in a variety of anemones, such as carpet anemones, condy anemones, and bubble tip anemones.
