Well, here's my train of thought at the time being....
Since I just discovered him @ WM yesterday.... and I know that he came in on their shipment yesterday one of 2 things must have happened.
either:
1) something happened to him in transit so the cut/rip is still fresh an NO regrowth has come in yet or
2) he was born tail-less
BUT.. if this had just happened to him very recently, he'd be going ballistic. He swims perfectly fine (although a tail's not needed for swimming really, in this case i guess) and he doesn't seem to be bothered by it in the least. He does try to wag it when he's flaring at himself, just like my regular boys do, but it doesn't bother him.
My guess is that he was born "special"....
but we shall see!
Okay, pics coming momentarily!!
