My crested gecko is a rare genetic morph, white lilly. In hindsight, I don't think I would have gotten him, had I known the breeding standards for the morph itself. In short, there is anecdotal evidence suggesting a higher mortality rate amongst juveniles. Breeding two lilly whites is highly unstable.
That said, I still think he's pretty and has been a good, healthy geck. Though, some tricolors will still achieve a similar pattern.
