Lately when I feed my Oscars, sometimes when they're chewing (Atleast that's what it looks like) the sometimes blow particles of food out their gills. This was normal to me because all of my fish have done it. But recently the food came out stuck to transparent Mucus like stuff. It doesn't look like a worm or anything living. It looks like tiny globs of clear snot. It's not every time they eat, just occasionally. They still behave completely normal and are eating like pigs. Is it bad or nothing that needs worry?
