I think Alvaro wouldn't mind if I link to some photos he already has on the web:

My understanding is that he has had this guy for several years and he hasn't changed so hopefully he is the real genetic thing.
On the other hand I got an imported female that might have been one of those one shed changer. She quickly changed appearances as she grew (stopped shedding clear and started picking up more dark pigment). I don't have a good feel for what the change pattern is with those changers so I yet hold out hope that she might be something genetic, just different. She has been off on a breeding loan for nearly a year now (stopped feeding too soon last year) so I don't know if she stabilized at a nearly normal look or something still pretty odd:
