Well, keeping it moist, not wet, is fine, as long as you let the ventilation dry it out before moistening it again. Generally, people don't keep them moist because its been blamed for deaths. High humidity, no ventilation, that will kill an Avic. I keep mine dry, with a water dish, but I do make it rain every few months, to simulate natural conditions. Which isn't a problem because I have good ventilation. If you like keeping yours moist, I would just check periodically to make sure it's not stuffy in there, and there's no mold. It's much easier to keep them dry though, with a full water dish.
