fish blowing bubbles

[Tom & Ab]

not really an emergency but my dalmation molly keeps going to the top corner of my tank and blowing bubbles not sure if there is a problem or if he is just abit mental ???

I have never seen that before so my vote is for mental

Have seen mollies go to the surface and rapidly open and close their mouth and perhaps that combined with something on the surface would make bubbles

How did i get involved in this anyway
