because the water is to cold
No, you don't have to do it. I have four glofish in a 2-and-a-half galon, but I advise you not to do it. Six inches of fish in a three gallon is too much. I advise you to either not get a fish or to get another tank, unless you want one of your fish to die.
The maximum is about 1 inch of fish per gallon of water for most aquariums.1"fish=1gallon2"fish=2gallons3"fish=3gallonsso on but I usually put 1 gallon at the end when I'm done putting fishI have 11 fish in a 25 gallon tank so they have a lot of room but it looks crowdedif you want a lot go high even if you like 10 fish 20 gallon tank you'll end up adding a fish here and there some die then you by more i started with a bunch and ended up with 11. it varies
You have to heat the oil first.
No, it will die now don't be cheap and buy a fish bowl. And get your fish a castle to so he can hide from you.
If one of your fish has a disease, it will pass the disease around. The disease might kill your fish(s). The one fish you are talking about must be stronger.

This will depend on the fish; sometimes fish are unhealthy when you buy them, or they were weaker than the other fish in the tank and they became ill from an infection or water quality issue.
the name of the salt water fish is not given. more to the pointy is that gold fish are fresh water fish- therefore salt water fish other than anteroom's or catadromos fishes would eventualy die. These fish die because the salt water is cooler than claen water. Also, it would depend on what the temperature of the tank was before you changed it.
To answer your question. Fish need to be fed as much as they will eat in 15 minutes morining and evening. I don't like saying this but I must for both the good of the fish and your concience. Your fish will die soon. You are being very cruel to the fish in your care. You are breaking the first rule in fish keeping very badly and can not expect the fish you have to live for long. The first rule in fish keeping is:- "1 inch of fish needs a minimum of 1 gallon of water". The reason for this is to make sufficient oxygen and swimming space available to the fish. A bowl is not a suitable container for any kind of fish.
gold fish. they are cheap and easy to replace if they die when the kids are away at daycare or school.
