I only have a 40 watt bulb on them. I do keep my new heater on at night only because if its off, it goes under 30 degrees in my room and their night time bulbs are only 25 watts. I'd say when my heater is on it's no more than 75 in my room. Ember doesn't look dull anywhere, in fact, he looks just as vibrant as he always does.
My mom thinks he's been spending too much time with his sister and her behaviour is rubbing off on him. It does seem like it, he used to be such a sweetheart. He has been hanging around with her more... Maybe they are secretly planning to escape from the tank... or drive me crazy!
