I have 4 convicts and it seems as if they're not pairing off. I've searched through many forums and they say that convicts are super-easy to breed. One is definitely a female as there are orange scales on the belly. The biggest one, which is about an inch and a half, Im not too sure about. It has lighter-colored scales (very few) on its belly. The other two are definitely males since they have uniform color all around but they are only an inch, the same size as the female. I've had them for a little over two weeks now but all they do is chase each other (no two in particular). Is something wrong?
