I think some hybrids are really cool looking. I do thinkt here should be an effort to mark permamently any hybrid to make sure it's identified as such.
HOWEVER...
I produced hybrid tegus and I could NOT find any way to permamently mark the babys. They were too small to chip, and no tag stays on when the animal sheds like tegus shed. Rings would have been outgrown.
With any snake that is large enough to be chipped.. (or lizard for that matter) that might be a possibilty.
As long as the hybrid is sold as a hybrid, then I think they are fine. I agree though.. F1 generation tends to be the cool ones, with all following ones drifting towards one parent or the other.
