They don't do anything special...they just look cool. People get them for their clown fish not knowing clowns don't need them and will happily host other corals instead.
It IS very cool to watch the symbolic relationship a clown and anemone can have, however there is no guarantee a clown will even host an anemone if you have/get one.
they look cool but that comes at a very steep price. That price being a complete nuke of your tank if it dies. Nems require special care like intense lighting and a mature tank.
I had one for my maroon clowns. Otherwise they host in a rock cave... and then I never see the male. And not everyone gets them because they think clowns need them. I just like them.
well jarock, they provide a home for clown fish, I will show you mine it's a heraticas crispa which was bleached when I got it, but it has now regained its zooxanthella
