HELP!!!!!

I wasn't aware that anemones could hurt fish if dmaged. Mine didn't when it got sucked thru a pump.
If your's is still attached to a rock, it isn't dead. I'd leave it in there and do a water change and add carbon. Watch the anemone for a while to see how it reacts. My rbta got sucked thru a Tunze stream and is doing just fine since then. They're tough suckers.
