Will any fish try to kill anemones?

[CleverBs]

I want an anemone for my fowlr tank I have no clowns I just have always wanted the a anem. Do any fish try to farm them? If clowns hosted it would they be safe from predatory fish like a snowflake eel and cat shark? The tank was a reef so lighting is all DIY Cree 3w LEDs and the tank has been running 9+ months.

Only fish i know eats/kills anemones is a bat fish. I think it would be fine with the wel and shark as long as it isnt disturbed. And no the clown will be lunch when those fish get larger
