I posted a new intro earlier this week. Since then our new kid (Atlas) has been found lounging in his water bowl a couple of days?? Is he thirsty or hot?
He could be hot. Sometimes they like sitting in the water. It can be dangerous if the water is deep or if they are left there for long periods (especially overnight). What are the surface temperature readings around your enclosure?
Well the hottest spot on the surface is 82. Today though after his lighting came on...he went into his cubby cave??? Except to eat a bit. Is it a concern, because he normally wants to come out.
82 is definitely not too hot. Is that basking spot temp or the temp on the cool end near the water dish? It's possible he is going through a sleepy phase which happens now and then. I would check his weight and monitor that though. If it is dropping then there could be an underlying issue. If it remains stable then he is likely OK since they adjust their metabolism to compensate during slowdowns.
OK then I advise trying to either get the basking light closer (no closer than about 12'' for safety and beam width) or try using a higher wattage bulb. You want to shoot for around 100-105 on the basking surface with areas around that in the 90s. Then a gradient down to 75-80 or so on the cool side of the enclosure. Providing that heat gradient will give options but provide temps high enough to allow for proper digestion and overall health. It may be the cool temps causing the slowdown so I'd start there and see how it goes once the temps are within a warmer range for a bit.
Chart you'll find adapted for CBD used by / cited by Dr.Brown here
is this from zoologists who observed a range of wild dragons' thermal behaviours
as good a guide as you'll find anywhere.
Preferred operating body temperature for CBDs is 36 degC.
I wouldn't let a CBD be exposed for more than an hour to temperatures exceeding 42 degC.
