Marine fish have kidneys, which pump excess salt into their pee so they can get it out of their bodies. They also have special cells in their gills that pump excess salt out into the sea. Together, these two systems mean that marine fish can stay hydrated.
Do fish like salt water?
Some fish species can live in both freshwater and saltwater. These species are called euryhaline fish. However, most fish species can only survive in one or the other based on their salinity tolerance, or how much salt their bodies can handle.
What happens to fish in salt water?
If freshwater fish are put in saltwater, they lose water from their bodies due to the hypertonic environment. Their cells shrivel and die.
Can saltwater fish drink fresh water?
To partially compensate for the water loss, ocean fish actually drink water through their mouths. To get rid of the excess salt they take in by drinking seawater, they excrete some salt through cells in their gills. Freshwater fish never drink water because their bodies are saltier than the surrounding water.

Can I put salt water fish in tap water?
You may have wondered if it’s okay to use tap water when filling up your saltwater aquarium. I would not recommend using tap water in your saltwater tank, not in the state it comes out your tap. Tap water contains chlorine, nitrates and other chemicals that can be extremely harmful to aquatic life.

What happens if freshwater and saltwater mix?
When river water meets sea water, the lighter fresh water rises up and over the denser salt water. Sea water noses into the estuary beneath the outflowing river water, pushing its way upstream along the bottom. Often, as in the Fraser River, this occurs at an abrupt salt front.
Is fresh water good for fish?
Ordinary tap water is fine for filling up the aquarium as long as you let it sit for several days before adding fish (the chlorine in the tap water will kill the fish). You may also purchase dechlorination solutions at our store.
Why saltwater fish Cannot survive in freshwater?

What happens if you put a 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.

What fish can survive salt water?
Fish that can tolerate a wide range of salinity at some phase in their life-cycle are called euryhaline species. These fish, which include salmon, eels, red drum, striped bass and flounder, can live or survive in wide ranges of salinity, varying from fresh to brackish to marine waters.
Can I put table salt in my fish tank?

- They are breathing normally.
Do fish sink or float when dead?
Most fish are slightly denser than water, so sink immediately after death. However, like a drowned human, they become more buoyant over time as bacterial decomposition produces gases inside the body. Usually, enough gas builds up in body cavities to make the corpse float, like an inflated balloon.
