HCA: Hermit Crab Association

Has anyone fed used coffee grounds or tea leaves to their crabs?

Edit: wanted to clarify, regular tea leaves (green, orange, red, black variations from different cultures; not referring to decaffeinated ones)

I’ve heard of people offering used coffee grounds, it’s safe. As for tea, I’ve heard of people offering green tea brewed and dry. Not sure on the other ones though.

If it's on the safe list, it's okay to do. If it isn't, I would avoid That is me, I'm a better safe than sorry person
