I have a trio of mad. grandis, all adults in a 65 gallon reptarium with live plants, doing great, getting fat. The females are about 7 or 8 months old, the male is older, but they are definitely adult size. When do they breed? The females certainly look gravid at times, but I have not carefully searched for eggs, I just leave them alone for the most part. Do you need to cool them for breeding, or do you alter the light cycle, etc?? How important is it to remove the eggs, if they do lay? Thanks for your help,

Females may lay eggs at that age, but most will be infertile and eaten again imediately after laying. Most females produce first fertile eggs between 12 and 15 months of age. ALso most females only lay between April and October, even though some tend to lay year round.
This seems to be largely independent from any changes in humidity or light cycle.
Also in most cases Trios do not work. Adult females are often territorial and not only will only one female produce fertile eggs, but also the inferior one can be stressed to death.
Since almost 20 years I do selection for less agressive specimens and now I can keep a group of 1,3 and most of the animals I sell can also be kept in groupos as adults. But for your standard grandis, that may hardly work

Hope that helps

They are still young so be patient. Listen to Ingo and soon you will be like my friend who has more grandis than she knows what to do with. When fully mature...they are like rabbits.

they are captive born and certainly doing great right now. I will watch them closely for signs of stress. Thank you for the information. Brad Lichtenhan
