Although I agree to be careful when handling, I believe people are confused about just how small a "baby" chondro is. Imagine the gumballs you would buy from the grocery store machines....that's a general comparison for a chondro egg. Babies are tiny in comparison to the one pictured, about the thickness of a shoestring or slightly less. If I had to guess, I would say the animal from the OP is 8-12 months old if kept on an average feeding schedule. It may be older. Definitely past the extreme fragile stage that hatchlings pose.
Good looking chondro too!
