lol, for being 14 you sure are aquiring a large collection.
I'm not putting you down in any way, but do your research before jumping into this one. Chances are low, but you could end up with a nasty snake. Will you be able to still safely care for it?
If your looking for an animal to handle regularly, perhaps a blood isn't for you. They are slugs. Beautiful and my favorite, but not much in the way of activity lol. Also, how long have you had snakes for? Would you be able to identify the subtle problems? Can you meet all the financial responsibilities?
Perhaps not a huge blood right now, but a sumatran short tail. If you want to get into bloods, go for them. Smaller, and a calmer disposition, plus, they're black.

cant go wrong with a little darkness.
If yes, then go for it. Make sure to research potential sellers, and as always, practise good quarantine.
