What you can get to boost the humidity is a "versa top". It's a glass top that folds and comes with a plastic attachment that slides onto the glass edge and fits the tank perfectly. You can put the ventilation holes into the plastic and put your screen top over the versa top with your clips. That's what I used to house my bp's when they were youngsters. I have a petco pastel female who is 16 months old and is one of my better feeders. Good luck.![]()
