Clownfish killing anemone

[cpage3]

Hey all,

I recently (2 months ago) added an RBTA to my reef system and I think my clowns are killing it. A few weeks earlier I added a GBTA and it is thriving (the clowns arent killing it).

I have a pair of true percula clowns in there with them and the female is tearing the RBTA apart. It is digging into its mouth and pulling out white stuff and eating tentacles! Also, they host in it very roughly.

Does anybody know why this is happening?Can I expect this to continue to the point where the anemone dies? The anemone has been moving around trying to get away from the clowns for the past 2 months.

Please any insight into this situation would be much appreciated. What should I do?

Thank you,
Chris
