The difference as it was explained to me is this...the ability of the animals cell structure to preform osmotic regulation...
Fish need a "certain" amount of salt in there bodies to function (electrochemical balance)
Fresh water fish retain salt (or they would "wash-out" from all the fresh water) and when placed in saltwater they "overload" on salt because they cannot expel it...
Saltwater fish expel salt (or they would become overloaded from all the saltwater) and when placed in fresh water they "washout" because they cannot retain it...
Some fish are setup to "regulate" the amount of salt in there system and can survive in rapidly changing salinities, such as ghost shrimp, mollies and and anything living in an "estuary" bay where the incoming tide and river outflow change salinity on a daily basis.
Oh, and gold fish life expectancy is approximately 27.5 seconds in my Lionfish tank...
