I feel your pain... I had a few "is that a lock??" moments when I first paired my bp's a while back. If it's not a lock, though, it's definitely courtship, which means they'll do it eventually, if this wasn't "it". It's terrible waiting for a real one though. I got my first *definite* lock on Saturday, and after seeing a few maybe-locks, it was thrilling!
Actually, looking closer at your pics, it seems like the places where their vents would be are a little far apart compared to confirmed locks I've seen in pictures. But hey, I'm new to breeding, so who knows?
Good luck to you, and keep pairing them up, they'll get there![]()
