Is this Danio breeding behavior?

I started this thread elsewhere and another member told me to move it to get more responses

I seen these 2 dancing around for awhile. The other week I was finally able to catch them in the act. Haha. Lately they've been doing it almost nightly.

I'm not exactly sure what they're doing. I thought someone here might be able to help. My guess is they are "flirting". If so, I guess that is a good sign.

now I don't know much about danio's but my guess is that they are fighting? maybe... but don't take my word for it. Hope this helps.
