Are Emerald Crabs safe for BTA's?

[redvipe2010]

I have several BTA's and a few bubble algae appearing on some rocks, and of course they are the rocks on the bottom, and a pain to remove, and was wondering if I could get an Emerald Crab to take care of the problem, but I don't want them bothering the BTAs.

That would be fine...i have a RBTA and a few large emeralds,never been a problem.And i did have a bit of bubble algae,they took care of all of it,quickly.
