Birdsnest and emerald crabs

[Hiker4twenty]

I have 2 emerals crabs in my tank that wont leave my pink birdsnest alone. Since I put it in the tank on Saturday they have both been hanging out in it. They don't seem to be picking at it. Will they hurt the coral at all or stress it out?

Are they scraping algae off the plug it's on

If they are small frags, then the Emerald Crabs could prohibit them from extending their polyps, and thus interfere with their feeding. Otherwise I don't think they will hurt them .

They don't really do much besided hang out in it. The will claw at each other if they get too close.

Its normal for crabs to hang out in SPS corals.As long as the polyps can open,it shouldnt hurt your birdsnest.

The polyps that are directly where the crab touch don't open, but the rest do. I guess it will be ok then.
