Hi,
My male has been really agressive towards the female lately.
I always catch them mating. If not, and he's active, he's usually biting at her shell.
He has done damage. Small fragments of her shell have chipped off where her head is.
Here it is the middle of a cold winter in New England, and that male just won't give up.
What would you recommend? Is this common? Just how much permanent damage can he do to her?
Thanks!
