They turn upside down and don't move. If they jump out of the tank put them back in to see if they are alive. They sometimes stay alive when out of water (there're called miracle fish)

You can definitely do that, but you haven't made it clear that you have cold water in the tank before.

The plural of fish is fish. An example sentence is below for both singular and plural use. Singular: "Mark has a fish tank with one fish." Plural: "Susan's fish tank has three fish." If there are different types of species of fish then yes I suppose the plural is fishes, but if you are talking fish in general it is fish.
almost any other type of fish just make sure their bigger than the gold fishes mouth or the goldfish will eat it
