Why does freshwater kill saltwater fish?
If put in a tank of fresh water, a saltwater fish's cells would swell continuously, trying to dilute its salt concentration.
The effects of osmosis
are deadly for saltwater fish when placed in freshwater. As a fish's cells begin to swell, its body will take in excess water, causing a condition called osmotic lysis.
Can you drink salt water to survive?

brackishwater

pure distilled water can be fatal to fish
as it will significantly impact pH levels.
Can you drink sea water if you boil it?
Making seawater potable
Desalination is the process of removing salt from seawater, making it
