Hi Helios, there was no malicious intent in my reply to your original post. Just a general caution as we as keepers have so much more still to learn about animals in captivity. It is good that your brought your case to the public domain however we have to flip the coin and reveal both sides.

Based on my experience with sauvagii, they have many (vast!) amount of eggs. Going back to evolution, nature has its way. There are bound to be faults in the line, even when reaching adulthood. Just like us Humans, Cancers, Liver Disease, Heart Defects... the list goes on. This applies to all Animalia, Plantae and all living, breathing organisms.

To think that all animals put into captivity under the right conditions, fed the correct food source and generally doing everything right is one of the biggest misconceptions in our hobby. Sometimes nature just has its way and unless (I say this with utter sadness) your frog was stripped down and fully examined, we are simply left scratching our heads.
