I have my pair in the first of my 10 verts on my new rack, which has several film canisters and broms as lay sites. They have become so bold since I moved them from their quarantine tank, that the male will call even with my face pressed against the glass. I can't say that I've seen any interest at all from the female though. They're both roughly 6 months old, and I'm pretty sure a 1.1. Is there any way to tell for certain? If they were both males, wouldn't there be some confrontational behavior between them? I could post a pic, and maybe someone could make a judgment based on body size?
