Dib Dabs, just wanted to comment and say your female is just gorgeous.... love that coloring!
Rick, many people may not agree with me, but, if you see no aggression between them, I'd leave them together. I had a male and female and they got along beautifully, before during and after spawning. In fact, until "I knew better", they lived in the same tank together. But, I was blessed with them. It doesn't happen often.
However, I'd like to see further clear pictures of your female to see if she's actually ready to spawn. Don't forget that the male will build a nest any old time, not just to breed. He usually does it because he's content. I wouldn't leave her in there forever. Just until we see what her story really is.
