Help with teddybear crab

[nemos-buddy]

I bought a teddy bear crab in it is eating my anemone. I don't know if its eating it but after putting him in the tank my purple lt nem has been shrunken up and it went in a cave. I thought it might die. So when I moved the rocks to get him out I see the crab is on him. I moved the nem to the outher side of the tank. And he has stayed little for like a week. So thing it was dead. I go to get it out and see the crab on him again. It looks like it has been eating on some of the tenticals. the ltn still looks to be alive so I put it in a glass and put the crab in a glass in the tank. I don't know what to do.

The crab may need a new home in the refugium for the nem to survive.
