I got a blood python about 3 weeks ago. He was very sick looking. His skin was really loose on him. the last owner had him in a desert tank. no water and very poor conditions. when we received him he looked like he needed to shed. I asked one of my friends that knew the kid how long the snake had been shedding and he said at least since febuary. We put him in a tank thats fairly good sized with water in one side and heat in the other. now he shed (with lots of difficulty) and he's looking better. he actually fits into his skin now but now he has these blister spots that when you touch them they leak wattery stuff out of them then they dry up. any clue what they could be?
