Hi, I got a leopard gecko like 3 weeks ago and have had a red bulb on the terrarium for heat. I've read that leopard geckos are fine with having a red bulb on all the time, however I've noticed that her pupils dialate when close to it....will this be a problem with natural diurnal cycles or what. She is feeding and growing well; and shows no signs of things being bad. Just curious if anyone has had experience with using red bulbs as heat....thanks, prob just being paranoid.
