Rock anemone and horseshoe crab

[DaFrog]

My florida rock anemone (about 4 inches across) swallowed (once more) my horseshoe crab (about 2 inches long excluding the tail) - It was too deep in for a rscue and now, 12 hrs later, the anemone has a few blueish hues - Should I set up a quarantine tank for it? Should i try to extract the shell that might be hard to digest - If so, how?

Thxs in advance

What did you do when it happened before?

I was able to pull it out as the anemone was only closing on it and was not yet inside the mouth
