Oh yea, he is fine. I was just curious if it was maybe some sort of hybrid or other variant of the RTC. Either way he ain't going anywhere, one of my favorite fish ever.
And I will likely get/make a pond, I just use the term "tank" & "home" loosely. Unless I can find a steal on a 6x3 - 8x4 size tank I wouldn't bother anyway because anything smaller would only last a little longer than the current home. And the odds of finding a CHEAP tank that size is like winning the lotto. So most likely he'll get a stock pond, round pool, Rubbermaid tub (Unlikely as they aren't that big), or I'll build a frame and put a pond liner in it.
Likely the last option so I can make it the size I want.

No knubs that I have ever seen, or trace of them and I've had him since he was a wee 3" baby. I'll look close tonight and see if I can see anything. You may be right on the birth defect thing.
