Terrariums are great for plants that require moist, humid environments. Succulents don't usually prefer these types of conditions. Because succulents use their thick, fleshy leaves and stems to hold water, they don't need moist, humid conditions.
They may not be HUGE but they are unusual in shape and size: Jerboas are technically desert dwelling rodents who live primarily in Northern Africa and Asia, but let's face it- they might actually be the cutest animals in existence. I LOVE Jerboas!
