It just needs to be clean I don't know if a goldfish can even live in salt water. I always put the ones I've had in tap water that set out for a day or two I don't know wye it needed to sit out for a couple of days before putting the fish in it but that's how my mom always did it so I figured it was probably for a good reason. I actually had one goldfish that lived for like 4 or 5 years that's a long time for a goldfish.
Goldfish need to be kept in fresh water, they are not made to live in salt water. preferably, keep them in spring or kangen water. By the way, you mom left the water out for a day or two to get it to be room temperature. Goldfish need to live in water the temperature of 70-75 degrees Fahrenheit.
fresh water
No.
No.
Please don't. goldfish are freshwater fish, not saltwater.
possibly because brackish is a mixture of fresh and salt water and goldfish cant live in salt water so yeah most likely.
I wouldn't think so as goldfish can't live in salt water.
No, absolutely not! Brackish water has salt water in it and it will die because of that!
Salt water, water that is too hot or cold or has chemicals in it
No your goldfish did not "evolve" it "SURVIVED" being put in salt water. You don't say how much salt is/was in the water but placing a goldfish in water to which 1 teaspoon of salt has been added per gallon is a commonly used cure for fungus. Goldfish did not evolve they were selectively bred by Chinese aquarists from a species of wild Asian carp (Carassius gibelio) that had evolved over many millions of years.
It depends on the fish. If its a tropical fish that is accustomed to salt water, you need salt water and you need to keep the water at a warmer than norm temperature. If its just a regular goldfish, freshwater at room temp should do just fine.
The water will evaporate and salt will be left ... so unless you want salt it is imposible to clean salt water with the sun
Yes. Freshwater fish do not drink water, but instead absorb their water requirements through osmosis from their skin cells. Salt water has a lower concentration of water molecules than the water concentration inside the body of the goldfish, thus water moves via osmosis from areas of high concentration to areas of lower concentration. In this case, water would move from the goldfish's body to the salt water, resulting in dehydration of the goldfish, and eventually, death.
