Tube Anemone

Hello all, does any one know if it is safe to keep a tube anemone in my 125 gallon mixed reef tank. And i read something about them having a powerful sting. if so would it hurt me? will it eat any of my reef fish? my fish are:
~Blue Hippo tang
~Pair of Clowns
~Chromis
~3 stripe Damsel
~6 line wrasse
~LMB
would these fish be effected by a tube anemone?
P.S.~if anyone has one and could post a pic, that would be great!
