NANFA-L-- Gasping for air

Hi all. My lone Poecilia salvatoris female gasps air-in-the surface whenever I shut the filter off to feed the fish in that tank. A few of the juvenile P. velifera that I have in the tank with her have started doing the same thing.

The fish eat well and seem healthy otherwise. I don't think water quality is an issue as I do a 75 percent water change on the tank weekly.

I was thinking it might be some sort of low level infection of the gills. I've treated that tank with prazipro, but without much success.

Anyone have any ideas?
