Unlike the Dino Pet, the Dino Sphere is an open system- the plug is ventilated so you don’t need to worry about removing it for air exchange. At night, dinoflagellates (dinos) enjoy a midnight snack of simple sugars, producing CO2 during the process. During the day dinos photosynthesize, producing O2 as a byproduct. So you don’t need to worry about giving them any extra air- they’re able to produce everything they need!
