I set up my 30x30 exo-terra tank with heating pad on the outside bottom,added the sand it came with and a couple inches of moss,i then added the water dish and a hallowed out rock.for light a put a purple 25 wt moonlight,its sittin at about 80 degrees f.I bought an emp scorpion yesterday with the crickets and its food. My question is , hes been hiding under the hallowed out rock all night and most of the day, is this normal adaptation ?
