It should be fine...
i have a large hatian condy with a disc size of about 5" and tenticles about 6" long...this thing is huge. Had the LFS guy come by the crib to check it out and even he was amazed. He also almost pooped himself when he saw that my maroon hosts with this anemone.
I have an undulated, niger, and a maroon clown. The niger is the only fish so far that was dumb enough to chase the clown right into it. He did get wounded, it looked almost like a burn on our skin. Had two blue devil damsels, before i caught them and gave them to my buddy, that would never even think of coming close to it. Had a kole tang and a small red coris wrasse, that both died, that would stay clear of this condy also. Depending on how big they are and how much room you have they should be fine. The reason i state that is that i'm currently running a 55l and this condy was dead center in the tank. I had to move him because the other fish couldn't swim by.
Don't listen to just me only, this is only my experiance.
