EXACTLY thats the big difference with Bloods. What you can get away with through lack of experience and understanding with other species of snakes you can't with these animals.
They are not a species to "learn on" imo and while they can be puppy dog tame etc they do require an understanding that differs from a beginner snake for example.
Corns and Kings are ideal for beginners then perhaps a step up imo is pythons when your dealing with temps and humidity with some flexibility ........then comes bloods that require more precise husbandry and understanding.
thats not to say no beginner can keep a blood but for the masses with little or no experience its not an ideal 1st snake.
just my opinion though.
