the tanks are more durable than you think...keep them secured and immobile and you should be fine. Put them with tubs or with bags of clothes. or put them in the backseat. the only thing you would have to worry about is very hard objects or rigid angular objects. Make sure you keep them empty of ceramic bowls or hard decorations before transportation. Obviously (I know you know) do not transport the animals in those tanks. Please place any snakes in bags\pillow case or proper transport medium before moving. You will be fine no worries!!![]()
