Removing Pulsing Xenia from Clam

[pacificfloor]

Thanks in advance for any information anyone can give....

Pulsing Xenia - we like them, but of course they're taking over! One is now on the shell of a jeweled clam, and is very close to its mantle. We would like to remove the Xenia from the clam before the clam is injured or killed, but are afraid that removing the Xenia with tissue scissors will just create more Xenias (true??). Pulling it off as I have in the past won't work this time, as I've tried this and it's just too firmly attached.

Any advice?

Scrape it off with a sharp knife. Then scrape it off again when it regrows. Then scrape it off again when it regrows......
