Yes. I put my goldfish in water strait out of the sink. We have a well so I dont know about city water, but I know that you can put well water strait out of the sink. Hope this helps.
Unchlorinated water, such as bottled distilled water is best.
No, if you put a goldfish in hot water it will die.
If there is water in there...
you put it somewhere where there is no sunlight or light because goldfish die in the heat so use cold water and put it somewhere cold but not that cold
No you cannot put a frog with goldfish; goldfish belong with goldfish
Yes you do!!
You need to provide 1 gallon of water per inch of fish. Goldfish get along fine with other goldfish.
Put it in a bag of water until you've finished changing the tank water.
goldfish will survive in tap water but it is best to put a bit of chlorine control in the water plus you will need a filter if you want the water and tank to stay cleaner for longer :)
No, goldfish are best with goldfish with the exception of weather (dojo) loaches, bristlenose plecos, and apple/mystery snails.Although goldfish can survive in warmer water temperatures, they are a "cold water" fish and not a tropical fish.
three fourth of the bowl
You can put it in there but why should you? Are your goldfish sick? Are they in need of medication? I am of the opinion that the less chemicals added to a fishes water the better the water is bound to be. Why add chemical solutions and try to fix something that is not broken?
