this is an appropriate forum to ask any reptile housing question. Now as far as size of cages go as far as how big is to big can be a hit or miss situation. I have some animals that do just fine in larger tubs than others. For instance, my 05 male citrus ghost that is right at 700 gm does just fine in his 41 qt tub with just one hide. However, I have another 05 female het pied that no matter how many hides I put in a 32 qt container she goes off-feed and she's over 900g. She can go 2 months without a meal in the mid size tub and 5 mins after going back to the 12qt tub she will nail a pre-killed med rat. I know she's too big for that small of a tub, you know she's too big for that tub, but she don't know that, lol. My general rule for moving snakes to larger tubs is this. If the snake is unable to move completely onto the cool side of the tub without knocking over the water dish then she/he needs to get moved up. My tub ranges are 12qt for hatchlings, grow up/ small male tubs are 32qt and large adult male and female tubs are 41qt. I usually have to move the babies to the 32's at around 400-650g. Then they move to the 41qt's at around 1200-1500g. My largest female is over 3000g and is able to stretch her legs in the 41qt with no problem. The smallest animal i have in the 41qt is my male citrus ghost only because he's a champ eater and roams more than any other ball python I've seen, I mean he thinks he's a dang racer or something, lol. In my experience a cb70 would be a little to large for a 400g snake and may stress a little, especially at first. If you are not planning on breeding these animals a few months without a meal won't be terrible and they should come around eventually with minimal handling/outside stress. However, if you are planning on breeding these animals, you will need smaller racks eventually so why not build a med size tub rack now and in a few months build a larger rack and a hatchling rack. Hope this helps and sorry for so long, just trying to throw a little of what I've learned out there.
