no because if it is salt water that you have them in and they are a fresh water fish it could effect their health and they could die so which ever kind of water they are supposed to be in your a lot safer keeping them in that kind of water

piranha fish...
Both kinds of fish can live in a delta area. The line between salt water fish and fresh water fish seems to be getting blurrier. Sharks and other typically salt water fish are found many miles up stream in rivers that empty into the ocean. It appears that salt water fish adapt better than fresh water fish as the fish found in fresh water are not found out at sea.
it depends... is it a salt water or fresh water type of fish. if it is a fresh water kind there is something wrong with it but if it is a salt water kind apparently some have been found to swim backwards for no apparent reason.
Dolphins look like dolphins and why would they look like a fish when they are a mammal?
the answer depends on the fish species. if you didn't get the fish at a pet store, and found the fish in the ocean, keep it in saltwater. if not, use freshwater.
