how big is your clown? I have one that Ive had one that was the first fish in the tank but I bought him small because its in my 24g pod. I give him no anemone because that only makes them more territorial, but recently he started taking to the frogspawn. even now that he is hosting he hasnt been all that aggressive. I attribute that to the fact that its just shy of 3 inches. usually when a fish gets big, they get mean. I would trade the one you have and get a smaller one.
