I just recently transferred my pastel female from a 20-Long tank to a 40, and after 2 days she isn't using any of her hides. My ambient temp is 78-80 and my hot spot is 83-86, and a super solid 64% humidity.
I have 3 hides currently in the tank, one in the back right corner over my UTH, one dead in the middle, and one in the far left corner. I have a great heat gradient going on.
Anyway, she won't use any of her hide's, and I've never had this problem before. She will use one for an hour, then go lay out in the open, then use a different hide. Just a random cycle.
Before anyone flames me for having a juvenile in a 40, I'd just like to say I haven't ever had a problem before... as long as I have 3-4 hides in there. To me it just seems like she's being restless.
