Substrate preference for larger enclosures?

[Neal]

Thanks for the putty knife recommendation. For now I'll have the dividers in them and my female BCI's can live in them. Fortunately their messes aren't bad, and at least they're not at all aggressive or nasty in case I do have to climb in to do some deep cleaning in those back corners.

I'd still be careful when climbing in because you'll have restricted movements.

I say use unprinted newspaper but you'll do better with Cypress because it holds humidity better.
