Alright...so I've seen this happen once before and thought it coulda been an accident. I had crickets in the cage and my geckos were feeding. The female bit the males tale, I thought make it could have been just an accident. Tonight I saw the female like shaking under the log so I was like what in the world. So I lifted up the log and the male was biting her tail. What the heck is going on? lol. Is this some sexual thing that I'm unaware about?
