BellaOnline Forums Home and Garden Exotic Pets Hermit Crabs

My grandson is interested in Hermit Crabs. We have been researching on their care and need information on what kind of substrate to use. I've read sand, gravel, Bed-A Beast. Want is the best to use and how deep. Also for three crabs, what size tank?

I use coconut coir. It is a renewable resource, and my hermit crabs seem to love it. They can bury themselves into it, and they also like to eat it, from what I have read.

I also have 3 hermies, and I bought a ten gallon fishtank at a local thrift shop for $3.
I put about 3 inches of coconut coir in the bottom. That seems to be enough.

Here is a great website to help new hemit crab parents:

I got a lot fo info about their care from this site.
