I've heard of people doing that, but it's still no guarantee. Unfortunately, you can't force a clown to host something. Free fishy will at work here.
But hey, if that works for others, it's worth repeating! My clown has steadfastly ignored my two anemones... and decided to host a feather duster worm. LOL
Someone stop me! Please! But... not just yet...
