I have a black blood and a Sarawak short tail.

Q1: I agree with the messiness. My sarawak is much younger and isn't quite the slob as the black (which is a 3 or 4 year old adult). I've had to clean out her enclosure many more times do to a dumped waterbowl. Sometimes, I think she just wanted a sauna for a bit. Also, out of all my snakes, she's used the water bowl as the toliet more often.

Early on, I had some difficults with the black's setup, and she picked up on an RI. I had to get somebody else to help me to give her the shots. She's just so strong. Only once did she not struggle when given the shot, which immediately concerned us, thinking something was wrong. My vet tech friend was acutally giving the shots, I was helping to restrain the black's body a bit. (And she made a giant pee/poo mess at the vet, both times while being given shots).

Q2:
As a baby the sarawak was a bit nippy, but sarawak's are supposed to be more laid back than the other two speices. I picked up the black as an adult.

Q3:

The black is in the largest tub sold by reptiletubs. I'd really like to get her into a boaphile, which would make cleaning quite a bit easier. I use a corrugated cardboard for her substrate, which is fairly absorbant. The sarawak is in a "sweaterbox" size plastic tub, I think. The temps and humdity are what the caresheet says.

Q4: I think the largest I've seen was probalbly 4.5'. It was hard to tell, she was sitting in a big plastic bin with another blood at the swap. (They were on their way home at the time).

I'd say my black is a little over 4 feet.
