Why can't a saltwater fish live in freshwater?
If the salt water fish were to be put in fresh water then their high salt content inside their bodies (to prevent too much salt diffusing into their bodies) will have it diffusing out down the concentration gradient; killing them. If the fresh water fish were to be put in salt water then their low salt content inside their bodies (to prevent too much salt diffusing out of their bodies) will have it diffusing in again down the concentration gradient; killing them.

When making salt water for marine fish what ratio of water to salt do you need to keep the fish healthy?
One pound of salt for every one gallon of fresh water. Also, as the water evaporates, add only fresh water...and slowly! When I kept fish, I would drain half of the remaining water, then mix in the fresh water, then put the mixture back into the tank. This prevents the fish from getting a fresh water shock. The water will evaporate and leave the salt behind, so if you add more salt, it will be too much.
