Welcome to AC !
I moved your thread to one of the marine forums where you posted is for articles and comments on articles. To answer your question no you don't need an anemone for you clowns they most likely haven't seen one in generations. They are easy to keep an anems aren't . Hope this answers your question if you have any more feel free to post!
Again welcome to AC!

Ditto---I have two happy healthy perculas and no anemone. It's cool to watch them swim in them, but unecessary and like Max said...very difficult to keep and picky about lighting and water conditions. Not to mention Iodine, etc etc.
On a similar note, most clowns are just as likely to host in real nem's as they are to host in certain soft and LPS corals, as well as fake anemones...
My clown currently has been trying to host in my button polyps for a while now but it doesn't seem to be working out for her...
A few years ago I had a dark maroon clown fish that hosted in a condylactis. They kept this relationship for over two years until I tore down the tank. Condy's are easier to keep, and cheap.
