don't you mean: what does the gill arch do in a fish?!
The gill filaments are the hair-like structures on the gills which absorb the oxygen from the lamallae. The gill arch, on the other hand, acts as a form of muscle which holds the structures of the gills together. ~Sincerely, A Smarty pants :)
The openings in the throat region of a fish that lead to the gill chamber are called gill slits. These slits allow water to flow over the gills so that oxygen can be absorbed and carbon dioxide can be released.
That is a hard but flexible cover which, in bony fish, forms the outer wall of the gill chamber. It protects the gills and also plays a major role in the pumping mechanism that regulates the continuous flow of water over them.
Bony fish have many gill filaments because they use them to breathe. They are also used to transfer things like water and ions.
They both make the plant and fish breath

so they can wee
All fish have some sort of gill, so that would be a yes.
The gill rakers on fish keep food particles from moving out from in between the gill arches. For filter feeding fish and some suspension feeding fish, the gill rakers function is to trap the food.

So long as the fish are not gulping at the surface all should be well.
