fish with gas?

[i love fish]

I kind of have a silly question.........
Do fish get gas? coz i sometimes see bubbles coming from their vent from time to time.
Also, does anyone know what a fish is doing when it opens it's mouth wide and erects its dorsal and anal fins?
thanks

When my fish have enchiladas & frijoles for dinner they fart. Other then that, not a problem.

funny I found this thread,, I was sitting on the couch last night and my clarkii let one rip,

my puffer turned and looked at him and my clown blamed it on my tang and the tang blamed it on the goby and the goby just kinda smiled.
