I think that they are very pretty.. But most clown fish books say that they are not a clownfish host.
That doesn't mean clowns will not host in them, and you can give it a try. but at the same time i have heard that they can sting a clownfish pretty bad.
they are inexpensive, and very hardy. I guess you could give it a try, doesn't work out give it to a LFS
Also, if you print out pictures of Clowns hosting in anemone's and put them on your tank, inabout a week, with the pics, and the anemone, your clowns may host.
Its worked for me.
