First I would like to thank everyone for all the wonderful info and help.
My rescued nile is doing well, right now he is in a temporary enclosure while I am having a custom one built, should be here by Christmas. He is eating a ton, and deficating just as much, has shed twice since we got him. He isn't very friendly in his cage, but is when he is in the bathtub.
His defence is always the same so far, hiss and tail whip, no biting, so far thankfully.
Anyway, I will try to get pics of all my reps as soon as possible.
