So for the first question, should I be looking to upgrade them to a larger tank? What size? They are currently in a 20 tall and I feel like the larger pools take up too much space, so they don't have all the roaming area they could. Or maybe I just want someone here to say, "Yeah, they really need a 50 gallon now" so I can show my husband and tell him he needs to suck it up and go along with it.

Along those lines, I've noticed quite a bit of the local places carrying sand that says "not for use in reptile habitats" - does that mean they are not safe for the crabbies?
My second question, which is more urgent, but I may need to post in the shells forum, is where is the best place to get new shells? One of them changed shells from one with an opening just under 1 1/4" to one with an opening just over 1 1/4" - so I'll need shells around that size and bigger? They seem to like the really heavy shells vs the lighter shells, and most of the shells we have in that size are fairly light.
