Hello! I'm the new owner of an emperor scorpion and absolutely love it! I had it for about 3 weeks now and today he's been doing something a little weird and its the first time I see him doing that. He's out of his burrow, butt up in the air against the heat pad (which is on the side of the terrarium). I'm thinking he might be cold.. but it's strange because the light has been on for a while and so is the heat pad. It should be at its warmest.. any idea?
