A strange thing just happened. My 6.5 months old p.grandis just laid two soft "eggs". But she didn't even try to hide them, she just let them stick to the outside of a bamboo stick and a few minutes later she got back and ate them. The thing is that I have another, older female in the same enclosure (no male, he's waiting in another tank) and she just laid two well calcified eggs.. Is this normal behavior for a young female??
