Gotta answer a few questions first:
How long has your tank been setup after the cycle?
How many watts and what kind of lights do you have?
Do you have a chocolate chip seastar?
How big is your tank?
Would you be willing to try Green Hairy Mushrooms before moving on to an Anemone? Most Anemone don't live long in captivity. Also, You Skink Clownfish don't really need an Anemone.
Bang
Sometimes it could. Clowns are known to sometimes host corals resembling an anemone if an anemone is not present in the tank. They do not always do this though.
