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.
Very few species can, such as the Betta.
clean the tank and while you are doing that put it in a small bowl but with enough room to swim with fresh water but make sure that if it is a fresh water its in fresh water if it is salt water it is in salt water
Fresh water
fresh water .my fish are 16 yrs old
Fresh water fish survive just as well as fresh water fish. Maybe this question isn't the one that you actually meant to ask?
Rivers,lakes.ponds,any fresh water source or there are fresh water fish breeders
yes what are the fresh water fish that lives with gold fish
No , some fish live in slat and fresh water but the pet fish you have or want to hve need fresh water.
The type of water you use in your fish bowl depends on the type of fish you plan to put in the bowl. You can use tap water, soft water and bottled water in a fish tank.
Well it depends on the fish. If it is a fresh water fish then it lives in fresh water, salt water fish live in salt water.
