Question

Which community fish will die with salt in the water?

Answer 1

If you put a freshwater fish into saltwater, most fish would lose weight

(from losing water from its body) and eventually die.  Approximately 2% of all 21000

species of fish actually move from freshwater to saltwater or from salt to fresh at some point in their lives, the move would kill any other fish.  But even with these special varieties of fish, the move must be gradual so their bodies can adjust, or they too,  will die from the change.  If you want to learn more about why the freshwater fish will lose water, (or why a saltwater fish in freshwater would gain water), look up the words  "diffusion" and "osmosis".
