I got the new Y/T's in today. They are very dark, almost black and the female has almost no yellow on her, maybe about a foot of dirty yellow with tiger stripes on the tail. The male is almost as dark with a little yellow on the face with a much brighter yellow tail. They are big and super thick, especially the male. He ate 3 medium rats and has been Flagyled and I'm waiting on the female to eat, but I will not treat her until I can have an ultra sound done. (thanks Carl!) I'm expecting a nicely colored male Y/T next week. He's a bit lean and has slight nose rub, but is supposed to have a yellow head and face and a lot of yellow on the tail end. Also 2 more adults within a few weeks.
