I'm looking for a cheap, effective means of keeping them as breeders for my Mangrove Monitor as feeders. Any idea on enclosures for them?

Almost all my animals are being kept in 50 gallon stacker totes at the moment. I love the versatility of these as enclosures. At some point my Mangrove and Savannah will outgrow them, but they're great for my roaches and crickets.

However, Geckos tend to scale the walls easily, and Anoles jump like no one's business. So I don't know if the tote will work for them long term. Not to mention the babies will probably be able to get out for the geckos.

I was considering a trashcan, not sure how it would work out. Anyone have any ideas? I don't need it to be visually appealing, I just need it to be functional with minimal effort (not needing daily upkeep aside from water changes)
