I've been keeping ball pythons for about three years now and have been thinking about getting my first boa, but I have questions that I haven't been able to answer myself.

There is a morph I've seen and I can't for the life of me figure out what it's called. It's got a very dark, vivid red tail and the body is mostly dark grayish, not brown. What is this morph, or is there even such a thing?

Do coral albinos fade to a pale yellow as they get older, or do they hold that color well their whole lives? If they do, is there a type of albino that will hold the pinks and oranges into old age?

Also, do they go off the feed in winter like a ball python does? Are they more or less difficult to keep than a ball python?

Thanks for any help!
