Anenomes in a reef?

[BC564]

I have a small ( 1.5 - 2") anenome in my tank.....and he does wonder around a bit but stays in his littlel area of about 6" diameter section. I just placed everything else away from that section and all seems fine. I have cleaner shrimp that actually pull food out of him when he closes up to eat. I have had no problems with having him in there at all....mine was a hitchhiker on a live rock.
