Ok I have decided to get either a few crested geckos or some snow corn snakes. I have a few questions on both. For the crested geckos what does the humidiy have to be set at and how tall does the enclosure have to be I have read the caresheets here and couldnt find that. As for both of them is at high 70's temp ok to keep them both at or do i need to get heaters. Thanks.
