First let me say that it's always nice to see more people getting into blood pythons. I think you'll find that they are wonderful animals.
what is a good time of year to get a pair?
You can usually find good CBB ones year round, but late summer seems to be when a lot are produced.
And from who?
This is key. I personally believe it is best to get a captive born and bred one FROM the breeder. If you go to the classifieds you'll see many supposide "CB" bloods available, but when it comes down to it, most of those are imports or CH bloods mislabeled. Either the person selling them knows they are imports but wants to make a few more bucks off them or they bought them from a wholesaler who "says" they are CBB.
There are plenty of good, honest breeders around. Ask around, i'm not 100% sure who has any available right now.
whould i be able to keep them together for their whole lives?
No, they need separate cages.
What would be a good size cage for one/two?
As juvi's they prefer tighter conditions, but as adults a 48" x 30" cage will usually be large enough for most bloods. Floor space key here as they don't typically climb.
Evryone always says it has the BLOOD temper, but then people say that most are very tame, so i know that with in the first few weeks he/she will be jumpy and nippy but do they calm down with handling?
I've found that their mood can vary as they grow. I've seen some that were agressive/flighty as juvi's turn out to be slugs as well as visa versa. I think the key is HOW you handle them. Bloods are very heavy bodied snakes and get very nervous when handled like most people handle a snake...meaning they need a lot of support to feel comfortable.
I want a pair of Red Bloods that is about a few months away from breeding so how much do you think the pair would cost me from? About $300-$600?
I hate to sound discouraging...but good luck finding any CBB adults that are a few months away from breeding. You're probably looking at ~$1000/pair if you can find any. You may be able to find WC adults for a lot less, but it may take longer than you think for them to acclimate and even then they will probably be VERY aggressive animals.
Does anyone have any good care sheets on any site that would maybe help me answer and more questions i might have?
NERD.com has a good caresheet as well as squamations.com and if you have any other questions, feel free to email me: matthew.hennek(AT)gmail(DOT)com.
