Hi,
Thanks for the advice. Unfortunately, I had tried using various ventilation techniques with this species in the past, and always ended up having them escape. As a test to see how much air was able to enter the vivarium, I pored some water on the to of the glass cover. The water was able to seep through the rim of the top and into the enclosure, so it seems that there is some ventilation. Mold and such problems were a concern to me as well, but there are numerous live plants growing in the vivarium. All of the species that I selected (miniature natives of Mexico) grow very large roots, which disturb and aerate the soil constanltly. In addition, the substrate is divided into natural layers of drainage, soil, and various surface covers. The soil mix that I created was duplicated from the soil of an Asian tree ant ant hill. And, of course, I let the tank air out and ocassionally stir the soil, so I think it should be fine. At this point, I feel that this habitat is probably as close to nature as it gets for a captive Brahminy blind snake... big spaces, NUMEROUS soil covers, a drainage level humidity gradient (The tank is at a tilt), as well as a top level humidity gradient, heat from above warming surface debris... a solid ant hill chamber, easily exitable pools of water... I think that I am off to a pretty good start. Thanks again for the advice.
