They often die so quickly that you might not even notice them getting ill, especially if it's something like columnaris.
Otherwise, it depends on what's ailing them. A lot of the time, their colour fades. Some fish develop dropsy (their scales stick straight out like a pine cone) which indicates organ failure, which is sure death. Others stop eating.

They have gills to breathe underwater and some fish have feelers so that they know where they are going.

A fish will most likely die if you put a cleaning agent in its fish bowl without removing the fish. You should remove your fish with a net and place it in another safe container until fish bowl is clean.
