Hi,
A clownfish will not wallow in any type of tube anemone, and for what it's worth, they seldom actually bond with any anemone, the anemone has to attach itself in the territory of the clownfish, and anemones seldom go where we want them to. In an established system usually the clowns have their territory staked out, and they stay in that area. I have seen clowns bond with fake anemones made of rubber (just an ugly algae magnet IMO). Mine loved the intake and out take tubes of my canister filter.
