I've got a mated pair of ocellaris clowns that decided one day that it was a good idea to stop hosting in my torch coral and start hosting in my old large featherduster, they're aggressive about it just like anemone hugging clowns they almost never leave the feather duster and love ruffling up in his feathers, the funny thing about it as most of the time the featherduster isn't bothered by it and only ever really retracts when the larger female clown tries to plow down inside the center of his plume, they've been hosting in him for a few months and when I move the duster elsewhere they just follow along and take up residence in him again, it's more comical then a nuisance in the tank, I'll try to get a picture up of this funny occurance.
