If she's content in the tank then you can leave her there but I'd probably try to switch to a rack. The male that's used to a rack might feel too exposed to be comfortable enough to get his groove on. Since the female will go through a prelay shed plus time until you notice eggs it's important to keep humidity up which is much harder in a tank. Another downside would be trying to uncoil her from eggs in a tank. It'll be harder to reach behind her without possibly being bitten since you really need to hover over a tank to pull them out. New momma snakes are NOT happy.
