If they stay in their hide most of the time that is a good sign. If they are out roaming during the day that usually means they are looking for a place to hide, and/or a different temp. Security is really important to them, if they don't feel secure in their enclosure and/or have a snug hide they will roam a lot and they may not eat. As for temps, sometimes they search for lower or higher temps. A good goal: 88-92 on the hot side and 75-80 cool side. Never above 95, and never below 70. I prefer my temps not to drop under 75
