Ok so I just read two different sites.. one said to NOT put salt because it prevents the goldfish from properly taking in oxygen because the fish already has a high salt content to its body so needs freshwater to help get oxygen. Another site said that they NEED the salt to take in air.
So should you put salt in a goldfish tank or not? As far as I understood (before researching) you were supposed to use salt with goldfish.
I have never kept coldwater fish (or goldfish.) I have a friend whose teacher was giving out goldfish to the students that wanted them. Her son is 9 or so. They dont know ANYTHING about fish. I explained to my friend that goldfish get BIG and cannot be kept in a small tank. She got a tank. I dont know what size. I'm thinking a 5-10 for right now and she said shed keep him there until it gets bigger. I dont want to 'tell' her what to buy. She didn't bring me when she went shopping. I am going to go over to help them do a water change. (They haven't done one in two weeks
and she asked me to come show her son how to do it, so I will be able to get the stats of the tank and fish when I go over.) I'll probably need some help identifing the type of goldfish. I'm thinking its just a common one. (Like the feeders) So if someone could just answer the salt question for me for now I'd really appreciate it. Thanks 
PS: I am going to be working on her to get a bigger tank ASAP. I'll be printing out info for her and stuff lol

I explained to Aaron (my friends son) that his fish is going to get BIG. Like about 15 inches or so (correct?) And that keeping it (even at the size its at now) in the 3 gallon tank is not healthy for the fish. I explained to him how the fish is being stunted and that it will stress the fish and kill it. I told him what I thought would be the best thing to do for the fish. Which would be to trade it in at our LFS (I know the owner) for a betta. Its a nice little tank with undergravel filter system. He doesn't seem too keen on the idea. He really loves his fish. I offered for him to come to my house and see my 6 bettas. I offered for him to also come to the lfs with me tonight to look at the other bettas. Dont think hes going to come tho. He has a friend with a big tank. All their fish died, so hes going to see what size it is and if its big enough he's going to give it to his friend so he can at least still see it. So obviously he wants to do whats best for the fish. He wants me to take it lol.. but I explained it wouldn't do well in my tank due to the fact that my tanks are all tropical. Hes just waiting to hear back from his friend. I told him even if he goes with me he doesn't have to do anything tonight.
