o.k. sharks live in salt water right? if you put salt in plain water could a shark live in it?

Answer 1

They don't only live in the sea, see this link, it's well-known to the point of it's name - the Zambesi shark, it goes inland until the salt concentration is just too low for it.

To explain saltwater/marine tanks, please read this: (it's more than just salt in water) It gives you a good idea of what's in a marine tank set up.
Marine aquarists commonly test the water in the aquarium for a variety of chemical indicators of water quality, these include:

Specific gravity, a measure ofwater denisty, is normally maintained between 1.020 and 1.024 in aquariums with fish only, and 1.023 and 1.026 for aquariums containing invertebrates. Salinity should therefore be between 28-32 PPT. Salinity is directly related to specific gravity and both can be tested with a inexpensive hydrometer or a refractometer.

pH should be maintained between 8.1 and 8.3 (can be raised with a commercially available buffer or through calcium-rich substrata); Carbonate hardness (KH) should be between 8 and 12 degrees. A calibrated calcium reactor can assist in maintaining both pH and carbonate hardness. Using purified water from a reverse osmosis / deionization (RO/DI) unit can prevent KH and pH fluctuation.

The nitrogen cycle refers to the conversion of toxic ammonia, to nitrite and finally nitrate. While fish waste (urine and feces), and decaying matter release ammonia, the majority of ammonia (approximately 60%) in both marine and freshwater aquariums is excreted directly into the water from a fishes' gills. Biological (bacterial) nitrification converts the ammonia into nitrite ions, NO2-, and then to nitrate ions, NO3-. Nitrate is readily taken up and assimilated by algae and hermatypic corals. Some nitrate can be converted by an anaerobic bacterial process to free nitrogen, but this process is very difficult to maintain. Most nitrate, which is less toxic to fishes and most invertebrates accumulates in the water until it is physically removed by a water change. Ammonia and nitrite should be tested regularly; any detectable levels (i.e., over 0 ppm) are indicative of a problem. Nitrate should not exceed 20ppm in reef tanks, or 40ppm in fish-only tanks. It is normal to have a little nitrate buildup, and some livestock handle it better than others. Most hermatypic corals, while able to assimilate nitrate, cannot be expected to perform well with chronically high nitrate concentrations (>40 mg/L as nitrate ion (~ 10 mg/L nitrate-nitrogen)).

Other suggested tests include calcium, alkalinity, iodine, strontium, molybdenum, and other trace minerals. Research the particular species you wish to keep to see if it is necessary for you to do additional testing.

Answer 2

This is a complicated question. First off, you can't put any marine fish in water made from regular table salt because the various minerals that are found in seawater would not be present. You have to use salt designed for marine aquariums and it has to be at the proper concentration.

Also, as other posters have noted some sharks have the ability to osmoregulate and can move into the brackish water (diluted seawater) where rivers meet the sea and some can even enter freshwater rivers and swim many miles up the rivers into pure freshwater such as Bull Sharks. Many species of sharks live in brackish water as young juveniles before they grow larger and move out into the sea.

Answer 3

Yes saltwater sharks are salt water. Adding salt to water does not make it a salt water tank and your fish will not survive. Salt water cycles differently than fresh water and will take close to a year of running before it will support a shark of any kind. Salt tanks mature at around 6 months to a year no matter how you started or cycled the tank. Until the bacteria in the tank is matured, it will not house a shark.

Answer 4

Sure.
People who have little sharks for pets regularly put salt in the water to make it live.
But do pay attention to the the proportions of salt you put in the water.
Cheers.

Answer 5

If you put salt in your tank it doesn't make any difference because what makes it saltwater are the materials you find on the sea and oceans. but their are some sharks that live in fresh water but very little compared to the big ones that live in the ocean

Answer 6

Depends on the shark Bull sharks regularly swim up rivers which obviously is fresh water. Other sharks do too but you really do NOT want to meet a Bull shark. Ever.

Answer 7

There are what people consider "freshwater sharks" but, they are really just a type of Catifhs ( I think ) ...

Real sharks would die in freshwater.

What kind of salt? What kind of shark? What kind of water?Silly question!
