Advertisement The "pet shop guy" told me, "Oh no! This spider wont need a heater. Room temperature will do just fine". I got him a month ago, and in October, where I live, room temperature goes down to high 60s w/o climate control. Caresheets found online recommends 75-85F. Currently ambient air temperature in my room is 84F, and T is sitting right next to the wall where I had stuck a heating pad on. Are these temperature recommendations correct? Or, different Ts have different temperature preference? My T seem healthy, eating really well and have increase in size (abdomen) since the day I got him. Is there anything wrong for him to seek heat like that? Is this normal? What's going on?
