Bubble nest?

[Jharvey]

I've heard about a bubble nest for bettas but I think my pregnant Molly is making one. Has anyone else had that happen? Or any other ideas for why?

(10 gallon tank, 3 danios, 2 mollys, lots of plants, 76 degrees, 0 ammonia and nitrites, <5ppm nitrates)

Might just be bubbles forming at the top, I know when I clean my tank, my heater forms little bubbles and they float to the top.
Do you have a picture of said bubbles?

Yeah, maybe it's not from the fish. It's just that I hadn't changed anything - I hadn't just cleaned it or done a water change or added any new fish, plants or food. Nothing new. So I'm not sure why the bubbles would come at this point.

Here's a picture.
