Scarlet Reef Hermit Crab Dust cloud?

[Wmacintosh]

i just watched my Scarlet Reef Hermit Crab go to the edge of the live rock and start spewing white cloud like dust. Any idea what they was?

This could be a few things. The ones that come to mind are pooping and breeding.

I assumed breeding. Wasn’t sure tho.

Sounds like breeding habbits, but i am not a crab expert.
