What happens if you put a saltwater fish in freshwater?
A fish that lives in salt water will have somewhat salty water inside itself. Put it in the freshwater, and the freshwater will, through osmosis, enter the fish, causing its cells to swell, and the fish will die .
Can you put saltwater fish in freshwater?

It's the first time fish have demonstrated this ability. Think about it: All faces have two eyes sitting above a nose and a mouth.
Are Goldfish Stenohaline or Euryhaline?
Most fish that can only tolerate narrow ranges of salinity and are highly sensitive to any changes in the levels of salt to the water in which they dwell. These fish are known as stenohaline species and include goldfish, which can live only in a freshwater environment.
Why marine fish burst in tap water?
Endosmosis is the movement of water inside of a cell when the cell is placed in a hypotonic solution . ... The cells of marine fish burst when introduced to tap water.
Do Guppies live in saltwater?
Guppies do well in freshwater aquariums, but their natural habitat is brackish water . Brackish water is part fresh and part salt, naturally found in swamps and estuaries, and easy to recreate at home for your guppies.
Will a fish replaced from a freshwater source to an aquarium with sea water be able to survive?
If a fresh water fish is placed in an aquarium containing sea water, it will not be able to survive because of the osmotic problems, they would face. Sea water is hypertonic as compared to fish, so it lost water through exosmosis and die due to dehydration.
Can a fish love you?

Why do fish burst?
