Hello Jobi, Hi Jeff:
I have to also tell you I have no problems understanding your posts. Your english is very good.
Second...to add a little about the light and dark controversy over hatching eggs. In the wild the eggs may just be placed in an inch or two of leaf detritus deposited in a depression in a branch. Not all eggs, just some. There is no reason why offering eggs a light and dark cycle would be beneficial to embryos incubated under artificial conditions. Many of their relative embryos are exposed to the same parameters in the natural habitat. A couple inches of leaf detritus sure won't stop the effect the sun (even when filtered through the branches of the trees) would have on eggs laid this way. The embryos might undergo periods of high activity which would make them stronger candidates for hatching. Try closing your eyes in sunlight. You can still "see" the brightness. At night the reverse is true. I agree that it could also affect color though maybe to a minor degree. Though these animals have been terrarium subjects for years there is still much to be learned about them. That's why forums like this are important.
There is another school of thought though that shouldn't be ignored. Under completely contolled dark conditions the eggs are safe from changing parameters. "Exposed" in a more fluctuating environment the eggs have to be monitored closely for moisture. Most people play it safe and go the incubator route. I like my eggs to "see more." I also think that many people feel the eggs are safer in the dark. I think this is a holdover from breeding tropical fish because there are species such as the Buffalo Head Cichlid (Streatocranus cassuarius)who breed in caves because their eggs are very sensitive to the light.
Anyway, that's my take for what it's worth.
You guys have a Great Day!!!
