Cuttlebone and food q's

[LeonardoDaPinchi]

Hello, I know that cuttlebone is good for crabs so I'm planning on getting one for mine, but I need a link to one that's safe for hermit crabs since the ones I find are for birds and such. Also, is there a way to not make food mold in the tank or no? Do I need to treat the cuttlebone before I put in the tank so it doesn't get moldy? Thanks in advance for help

The cuttlebone for birds is the same we give our crabs. We get it at Wal-Mart. No need to treat it first. The foods will mold due to the humidity in the tank. It won't hurt the crabs. Just change the foods out more often.
