HCA: Hermit Crab Association

I noticed on the safe food list, some foods have a diamond after them and some don't. Why?

At the bottom of the page, it says:
*This food list is mainly adapted from Summer Michealson and Stacey Arenella's book, The All-Natural Hermit Crab Sourcebook, and expanded on by Julia Crab and others.

And if you scroll waaaayyyy to the bottom, it says:
◇ Denotes HCA Update to the List

Basically the diamond is next to foods that the HCA has added to the original list over the years.

Hope that helps!

Oh, I didn't notice that at the bottom! Thank you!

No problem at all.
