I have 3 tanks in use and one extra, A 40 Breeder, a 20 long, a 20 tall and a 10 long. I am just wondering how you guys would use these to give the best environment to each of my Herps. Currently i have my 2 Crested Geckos in my 40 Breeder, however they do not seem to use the entirety of it and i think the size might even be overwhelming for them, i have set up a camera even during the night while i am asleep they still only roam the one half of the tank. I also have a Ball Python, who i really want to know what to do with, he is currently in a 20 long, and he is growing rapidly haha. I also have a 4 month old Carpet Python, he is in the 10 Tall atm. I am wondering how you guys would arrange these. i would like to put my Ball Python in the 40 Breeder, however the 20 long is about the same length so its not like it will make much difference for him since he does not climb, so my second thought was to put my Carpet python in the 40 breeder as he will need that tank when he becomes larger anyway, however idk if he is still too small for that enclosure. he is currently 38in long.

Thanks in advance for a quick responses.
