This has helped me alot and I enjoy looking at other ppls clowns. I have seen a sebae clownfish hosting a sebae anenome(maybe thats why their named that?) at reefcentral.com, anyways here it is http://www.reefcentral.com/forums/forumdisplay.php?s=&forumid=36
I have a pair of false percs that do. It took them about 3 months though. They decided one day to just anemone-jack the cleaner shrimp who would always stand by it. Now he's no longer welcome in the hood!
