Freshwater fish and saltwater fish are both healthy options. There are small nutritional differences between them. Their bodies do not absorb salt from seawater. The main difference in nutrients is that freshwater fish tend to have higher amounts of calcium, monounsaturated fatty acids and polyunsaturated fatty acids.
Also question is, what is the difference between fresh and saltwater fish?
Freshwater fish are adapted to live in a diverse range of habitats. Freshwater fish are found in shallow wetlands, lakes and rivers, where the salinity of water is less than 0.05 percent. Saltwater fish are found in various habitats, ranging from the cold Antarctic and Arctic oceans to warmer tropical seas.

In this way, what happens if you put a freshwater fish in saltwater?

How can fish live in saltwater and freshwater?
Saltwater fish can’t survive in freshwater because their bodies are highly concentrated of salt solution (too much for freshwater). The water would flow into their body until all their cells accumulate so much water that they bloat and die eventually.

Are fish naturally salty?
Why are salt water fish not salty to eat? Marine fish do not taste salty because get rid of the excess salt they ingest in order to maintain a balance of electrolytes in the body.
How much does it cost to get a saltwater fish tank?

Do fish see water?
The short answer is fish do not see water. Fish and sea creatures evolved the same way. So the answer is no. They do not see, taste, hear or smell water because it is a constant environment noise.
What fish can survive in tap water?
Tap water is treated with chlorine, and can contain metals. The chlorine will kill the healthy bacteria that the tank needs to survive and cause an ammonia spike. There are hardy fish—such as goldfish—that can easily survive the occasional ammonia spike, but there are delicate species that have a harder time with it.
How do fishes sleep?
The simple answer is yes! They are sleeping, and they can sleep at any time during the day or night. Fish do sleep with their eyes open, because they don’t have eyelids (except for some sharks) to close! For fish, sleep is more like a resting period similar to a daydream that humans might experience.

Do saltwater fish explode in freshwater?
If saltwater fish lack salt, their body salt will leach out into the fresh water, and their hypertonic cells will be filled with a lot more water than needed and explode. It is impossible for saltwater fish to live in freshwater because they have already adapted to salt water and high concentration of salt around them.
Can aquarium fish survive in a lake?

No, you cannot. Clown fish are salt water fish and the rest you have named are all tropical/freshwater fish. Clownfish are saltwater fish and need saltwater. Freshwater will kill clownfish very quickly.
Can fish live in saltwater pools?
Freshwater species like goldfish or trout die in saltwater. Maintaining the precise balance of ocean salinity required by saltwater fish is tricky. Saltwater swimming pools are insufficiently salty for marine fish. Fish excreting into the pool also makes this combination unsuitable.
Can goldfish live in tap water?
Goldfish cannot live in untreated water straight from the tap. This is because tap water contains chemicals that are bad for your fish. And, even worse, can kill all of the ‘good bacteria’ in your tank. The chemicals in tap water can kill some or all of the bacteria.
Can you eat bluefish raw?
In the past few years I have started eating bluefish raw (it’s amazing!); all you need is some good olive oil and a little bit of salt. You also can fry the skin and serve it like potato chips, which goes well with mayonnaise, or keep it simple and roast the fish whole.
