Three times now, over the last few days, one of my females has been clamping down her shell on the male's rear foot, and won't let go even after breeding. I found my male struggling to escape with a foot caught, and had to tap the female in the nose to release him. He didn't use that leg for two days, and I was worried that he could lose that foot, rendering him useless for breeding. After a long warm soak today, he seems fine, no swelling, though obviously a little sore. Has anyone seen this happen? Do you think that my male is in danger? Today, I saw a different female do the same to my other male.
