My green terrors had a growth spurt, the male grew faster than the female and is about 6 inches now, the female is about 4-5 inches including tail. They were almost the same size a couple months back. This week my female turned darker colors and her tube dropped, but otherwise they are not grooming a spot to breed. I thought she would have to be bigger than this to breed, or even drop her tube. Is she big enough to breed or is this normal for a young female? All my previous ones have dropped only when ready to lay.. (pics are in my gallery)
