Well, the advice to never buy a turbofan model is ill spent: I already have one. However, I do promise never to buy another one. Thanks for the rest. There seems to be some disparity about appropriate humidity, but I'm guessing if I keep it around 80% it should work. Also, I appreciate the advice about the females being too small--one was gravid when I purchased her, and the other has been kept with a male cagemate who I didn't think would be big enough to breed. Live and learn. I have separated those two. hopefully all will be well. Thanks again for the advice.
