I have a male and female betta in a tank with a divider. Somehow though, my female betta got onto the other side of the tank... when I got home, there she was, my two bettas were getting along, and my male had built a HUGE bubble nest. I don't know much about betta mating, but is this a sign that they may have? If so, what should I do to take care of my (potential) fry?
Also, as a side note, I noticed that he has been puffing up his beard when she comes near the divider... idk if that means anything, though.
