1. I keep my blood in a tub (they have a higher humidity requirement than balls)
2. Females and males will be big they are short but girthy snakes
3. Feeding schedule depends on age/size Bloods are great eaters. Right now mine is about 10 months old and already on medium rats. He eats once a week but I was feeding him every 4-5 days till he hit around 500g. Full grown adults can eat small rabbits.
4. Aspen should be fine. I have my guy on papertowel just because its easier to clean and keep some good humidity in his tub
5. He is housed right along on the same rack as my ball pythons and hopefully his new girlfriend as well
I would look up some care sheets on them. They are very rewarding snakes to keep but a little more difficult than balls. Here is a good one to start with
