So I've been sloooooowwwly constructing my first set of DIY breeding racks, and I've gotten far enough along that I could move my pairings out of the big Exoterra tank and into the tubs. And so far, so good! We had one escape the first night... but everyone's back in place, the tubs are secured (now with extra duct tape!) and the black pastel and pied have been going at it non-stop since Saturday.

But today when I went to check on everybody, I could barely see the black pastel & pied because the inside walls of their tub were COVERED in swirls of condensation. What's going on? They did spill their water bowl, but that was several days ago. Is it just because the humidity higher in there and the house has gotten cold? But I've never seen anything like that before.

Should I take them out? Or switch out the wet substrate? Or just leave it alone?
