Crab ID

[AlessandroB]

Hi,
I just received a Pink bird nest coral from a reputable online store, and, when I dipped it in coral rx I noticed that there was a crab (with two small babies!!) perched inside.
It has a very distinctive white top (see pictures), and maybe half inch size. Any idea of what species it may be? Safe or not?

Thanks both! So it sounds like a good guy, and should it put back in the DT right?

Yes. I hope he is still alive after dip.

Yes, it should be, I saw it right away and moved the coral in the “clean saltwater” Tupperware. It took a little bit of persuasion to separate them, but now they are already back together.
I realize now they are symbiotic to acros, so much to learn in this hobby!
