The wife has 2 more 'vampire' crabs (Geosesarma), the original two we had both died whilst trying to moult from their shells.
I made a new 'crabitat' from cat litter of all things. It has to be the natural clay type (Fullers Earth), mixed it with water and a mixture of bark, husk, and soil. When it gets to a consistency where you can mould it it's ready. I made tunnels and burrows with it and the great thing is that as long as it doesn't dry out too much you can continue to mould it and adjust it.
I also bought a reptile heat mat and put it under the tank to try and help keep the temp warm.
