Let me get this straight, i know the answer but i want to make sure because after so many years of having a bp in a acuarium, im used to 2 hides. But its too my understanding that if i were to have my BP in a rack system, i would NOT need a hide? or is it just one? or still 2?

UTH to a thermostat would still be there aswell as a waterdish (obviously) but how necessary are hides in a dark rack/system?
