My vagans is around 2-3 inches now and ready for a new enclosure. I have a 12in sq exo terra that is set up as a terrarium. The humidity ranges from 80 to 90% with day temps of 78 F and drops to 70 F at night. The enclosure has good ventalation I assume because no condensation forms on the glass and there has never been any mold or fungus growth. I found some info on the Vagans stating they have a med to high humidity requirment and shold not drop below 70%. But I am wondering if 80 - 90% would be harmfull.
