at christmas, we lost power, 3 days and nothing survived, except for an orange linkia starfish
before that, we had an18 inch carpet, and 2 percula clowns with a domino
the clowns were not even allowed near it. The domino, took right to it and played in it all day long, everyday. If anything came near the anemone, he would chase them out. Heck, the darn thing would bite me left and right, while I was feeding the anemone. would get nipped at least 6 to 8 times, every feeding. Luckily, the domino did not hurt, and is not venomous at all. It was amusing at first, but became very annoying FAST.
So, yes it is possibe, often different damsels will host in anemones, not jsut the domino. Just that clowns are more noted for doing so.
