Any beta experts out there? I recently rescued this lovely"lady" from PETSMART with the idea of letting she and my male have a little fun, then put here in a 20 I have for some color. He lives in a 5 gal all alone and I've put her in a breeding box hanging in the same tank to see how things work out. He doesn't seem to be paying her much attn. yet, to my surprise. He's built several bubble nests lately and constantly(even with her in the tank) pars with his reflection. So I got looking and wondering if I really had a female here. I've looked around a bit and seems it can be difficult to tell sometimes. The ovapositoris clealy visable but I guess that;s not always exclusive to females. Any opinions? Thanks!!

This is obviously the male
