If u have two females about the same size ,how can u Mark them to know Wich one is wich? I know u can separate them but can u put a lil bracelet,dye ,any way of doing it?
Sharpie permanent marker, mark a tail. It will come off with each shed though.
Each one will ahve a different pattern of her own of course, so really just looking at them in their natural form should be sufficient. Pick out some distinguishing spot or bar, and use that.
unless very young, you should separate them regardless of wanting to tell them apart.
