I just moved Santiago into his "big boy" enclosure over the weekend. Ive had him for 3ish weeks and i got sick of fighting the temp swings and humidity in the 10 gal plus he seemed kinda cramped. His new cage is a 36"-18"-12" exoterra. I have a heat mat on a thermostat set to 91 on the warm side and the 75watt lamp is on a dimmer currently at half power to help keep up ambient temps up on the cold side. The coldest corner of the tank, in the back right is about 76-77. Right under the lamp is 84ish. There is plenty of heat for little dude but he seems to prefer to be off the ground tied in knots around the cold plant. This morning he was on top of the plant on the warm side but tonight he's back in the cold corner. He doesn't seem to ever be on the tank floor which is very frustrating to me for some reason. Could he not like the new substrate? It's ecoearth, he was currently on aspen. Is he just settling in? Why does he want to be cold?
