Those look like breeding wounds to me Kay... Judging by placement and how superficial the marks are this is my opinion... Or it could be from a dominant female... I guess your next post will help clear it up... LOL
A dominant female in the tank was most likely the cause of this. I had a gecko with an issue with this. After its last shed you couldn't tell that it even happened. Just monitor closely and let nature do its thing.
Seperate animals if at all possible. Normally the more dominant female will most likely be the bigger one. That is not true for all cases but it's a general guide line to follow. I have had smaller ones bully bigger leo's.
