WOW, you better do some VERY serious mate finding and breeding atempts with your 2 boys, these are one of the most rare and critically endangered turtles in this earth, cientists think they may be gone in the wild within the next 10 years if nothing is done and they are very rare in captivity, both in zoos and in private hands. The clock is tiking for saving this species, do the absolute best you can to breed your guys. If by some reason you cant then please give them to a zoo or another conservation agency, at the moment they are just to scarse to keep simply as pets and every gene couts.
