What happens if marine fish is kept in freshwater?
If a marine fish is placed in a freshwater aquarium, then its chances of survival will diminish. This is because their bodies are adapted to high salt concentrations of the marine environment. In freshwater conditions, they are unable to regulate the water entering their body (through osmosis).
Can sardines live in ponds?
Sardines are basically a warm-water fish, but occur as far north as Norway. Schools, or shoals, of sardines swim near the water surface and are primarily marine, although some live in freshwater.

Can salmon live in freshwater?
SALMON and other so-called anadromous fish species spend portions of their lives in both fresh and saltwater. Life began evolving several billion years ago in the oceans and since that time, living things have maintained an internal environment closely resembling the ionic composition of those primeval seas.
What happens if you put goldfish in saltwater?
Goldfish is a freshwater fish so, freshwater aquarium salt disrupts the salt/water balance in the cells of harmful organisms, dehydrating them until they let go of your goldfish and eventually die off.
