I put my biggest two together today, Levi who is supposed to be a male, and Lucy, who is supposed to be a female. Took their hides out, put him in her tub... and suddenly they were the most active, looking-to-escape snakes in the world. With their powers combined they just about took the lid off the tub (which was latched securely!) after they completed two complete circuits around it. It didn't look like fighting, but it was still very strange. Is there any explanation for this behavior?

Totally going to a vet and getting them re-sexed before I try this again, that's for sure.
