Hi, I have a ceratophrys ornata and i have tin foil on the screen lid to help keep in humidity and heat. The only problem is that mold grows so I end up taking the lid off to dry it out and get rid of it. That doesn't work too well. How can i increase air circulation dramatically and deal with mold? Can i attach little fans to the lid? Should i add leaf litter and springtails? A response or two would be helpful.
