I bought 2 crested geckos as juveniles and they are slowly growing. The past few days I have noticed them hanging around on the bottom of the enclosure a lot. This is concurrent with the ambient temps in my room raising about 2-3 degrees up to 79 from 76 all winter.

The enclosures have feeding ledges, a hanging plastic plant, a potted pothos, and a climbing vine in each. Humidity is 40-45 and I spray the whole enclosure and all decorations fairly heavily each night.

Today this 'hang on the bottom' behavior hit the point where I feel I should ask if it's abnormal behavior or not. I went home at lunch to see one of my geckos sleeping in the dirt in the pothos pot, kind of shimmied in a little but not very much.

Reason for concern? At what point do high temps start to stress them out? It's the only variable that has changed that I can pinpoint. They're not breeding size and haven't been together at all, btw. What are they looking for on the bottom that I can give them? Thanks.
