I have had a number of people asking if my Giant Day Gecko is a hybrid and just had a few questions. First of all my male is WC, does hybridization occur naturally? Second I have had my male for two years now and just this summer he has developed blue coloration on his back, some on his head, and has a blue belly and throat, has anybody seen coloration changes like this before? Third I would like to call attention to the fact that there is such a thing as a blue grandis. Check out reproom.com which has bred them. Plus does anybody have any idea where I can find a female to pair with my male as reproom has sold their blue line to a zoo.

Here are a couple pics. Sorry for the poor quality as I had to resize them for the forum.

Hybridization happens in the wild but it's not uncommon for Giant Day Geckos to have blue on them. It's rare but it doesn't mean that he's part blue-tailed day gecko. If you are up to the challenge a female blue-tailed may mate with your male and produce the kind of offspring that you are looking for. Blue-tails look exactly like G.D.G. except that ther are smaller, have a lot more orange spots and have a lot of blue from head to tail. The hardest part is keeping the blue-tailed from dying since they are so hard to maintain.

Yesterday I found a website all about day gecko integration but I can't remember how I found it! I'll keep looking.

Yes,

intergradation zones have been described for mad mad and mad grandis. Maybe thats what your animal originates from.On the other hand its easy to imagine metabolic problems -genetic or not- which reduce the yellow and thus bring out the blue.
