Thank You, that makes me feel better. They seem to be getting along better and better all the time and groom each other regularly so I think they've settled in now.

I'm actually looking at a new cage for them at the moment, the one I have is kinda small and it's wire so doesn't all for much burrowing. I'd like to find something like it that connects to a tank. I just wonder if it would be appropriate for them, or if it's more for a rabbit or guinnea pig. Here's a link if anyone wants to give their thoughts or suggestions.
