80 degrees will eventually kill crested geckos, try mid 70s range. breeding takes place at all months of the year, and they are sexually mature at around a yr old. i seperate mine after ive noticed breeding, because the males tend to stress the females. they do need crickets, just not as often. they have clutches of 1 to 3 eggs every 2 to 4 weeks for a few months. theyre incubated at temps between 68 and 78 with great success.
