It will die!
Because saltwater fish can only breathe in saltwater (as in the ocean) and freshwater fish can only breathe in freshwater (as in tap water.)
Whiting are salt water fish - ocean fish.
No, pirahnas are freshwater fish.

No. True "goldfish" are freshwater fish.
Goldfish are freshwater fish which means that they do not live in the ocean.
Goldfish and bettas (fighting fish) are freshwater fish, so they are not part of the ocean's food chain at all. In a freshwater environment, they are relatively low on the food chain.

i think saltwater cuz they live in the ocean
No, freshwater fish must be kept in freshwater and saltwater fish must be kept in saltwater. The one exception (that I know of) in nature is salmon which migrate from where they were born (freshwater) to the ocean and then back to where they were born again to breed.
The same as in the ocean
