My understanding is that the original specimens that exhibited this trait were actually wild caught animals which were then bred together, etc., in Europe before offspring were sent to the US. The lack of pigment does create uncertainty with regard to UVB exposure impact and it will be nice once offspring are raised under varying conditions to test this completely. Looking at Mike's male, I don't see any outward signs of issues and it looks like a very nice animal. I typically don't like manufactured morphs but absolutely believe in maintaining purity of naturally occurring morphs like this. Having talked to Mike at length about strengthening the bloodlines with WC blood and tracking the hets, etc., I believe this morph is on the right track toward proper management. It will be interesting to see what we learn about them as time goes on and while they definitely aren't for everyone, they are interesting on many levels.
