HCA: Hermit Crab Association

This is Laura's Hubbie, Matt, again. Since the barley from my beer is ok for crabs I started thinking about what else I put in the compost jar that they may like. What about coffee grounds? I didn't see mention of them on either the good or bad food lists. I know that nightcrawlers eat coffee grounds and they're composters. What about crabs?

Thanks in advance,

Matt

I think someone had tried it a while back and noone was interested in the grounds. (if Im remembering right ) Let me see if I can find it!

EDIT: here is one, not the one I was looking for but oh well---
