I have been interested in doing the same. I find the tube anenomes attractive not only for their vibrant color, but they dont move from where you put them. I just bought a 4 inch Clarkii clown to go with my 6 in peacock in a 26 gal, Today is the first day, we will see what happens tonight... If all goes well, I miht get a tube anenome even though I have read that clarki's dont need anemones...
