Certain Freshwater Fish can survive saltwater conditions; examples are black mollies, mono's and scats. All of these fish aren't truly freshwater or saltwater, they are Brackish. Brackish is between freshwater and saltwater, and so these fish are highly adaptable.
A saltwater fish tank can be half freshwater and all of the saltwater fish will live but not for very long.
No, an Oscar cannot survive in a saltwater tank. Oscars are freshwater fish that thrive in specific freshwater conditions and cannot tolerate the salinity levels found in saltwater environments. Introducing them to saltwater would lead to stress, health issues, and ultimately death. It's essential to keep Oscars in a suitable freshwater aquarium to ensure their well-being.
No. Bettas are freshwater fish. Seahorses are saltwater.
Saltwater salt, makes it saltwater, for the saltwater fish to survive. Freshwater salt is added to help gill function, reduce stress, combat some health issues and improve water conditions.
No. Not in the traditional definition of the tropical tank. A tropical tank is a freshwater aquarium. Regal Tangs are saltwater fish and go in a saltwater tank (marine aquarium).
The density and pressure of saltwater is different from freshwater as is much of the bacterias and parasites. The acidity of the water is also of concern as the lower the PH the higher the acidity of the water. Saltwater being of a higher PH would not handle the lower PH of freshwater very well. Also if moving a freshwater fish to saltwater that fish will lose a great amount of water in it's body causing death and if the saltwater fish is moved to freshwater it will gain great amounts of water causing death.
No. Glo fish are freshwater organisms and lobsters are saltwater organisms. And if they could live in the same water, one eats the other.
Yes but you need to buy a saltwater filter to replace the freshwater one.
No, A Seahorse can only live in saltwater and a glofish can only live in freshwater. Seahorses do not do well with other fish anyways.
No, i wouldn't use it in the freshwater tank. It's been sitting in salt for quite a while, and chances are your salt water sand is comprised of bits of shells. They will throw off the chemistry of your tank and lead to fish loss.
uhhh.. yeh buddy
Nope i don't think that would work as jelly fish are not pets and are used to salt water and huge spaces. It would be cruel to keep one in a fish bowl. ;-) YES THEY CAN LIVE IN FISH BOWLS JUST POUR A BAG OF SALT IN THERE, TOSS THE JELLYFISH IN AN YOUR GOOD. DON'T LIE, A JELLYFISH COULD BE KEPT IN A FISH BOWL.
