well, not long. i had a goldfish and it died in like 8 hours.
There are several possible reasons why your goldfish may have died overnight. Some common causes include poor water quality, sudden changes in temperature, overfeeding, lack of oxygen in the water, or diseases. It is important to regularly monitor the water quality in your fish tank and ensure that your goldfish are in a suitable environment to prevent future deaths.
Unchlorinated water, such as bottled distilled water is best.
The water should be at room temperature.
If they die and pollute the water, yes. Clams need moving water, they are not suitable for fishtanks.
Goldfish spawn in groups in springtime when the water temperature approaches 70F. They do not have live babies.
Yes, a betta is a tropical fish. Tropical fish all have different temperatures at which they do best at, but goldfish are coldwater fish. Coldwater fish come from from a variety of different temperatures as well, so yes there is a temperature difference. You could not keep goldfish and bettas together because of the temperature difference.
Just leave the aquarium at room temperature.
You should keep the water at room temperature.
Please don't. goldfish are freshwater fish, not saltwater.
They start to come into breeding "mode" when the temperature gets over 65F.
it depends on what type of fish.a goldfish has to be in room temperature water.
They can but they shouldn't. Gold fish like colder water and guppies like warmer water. They can live when the water temperature is in that in between range when they are both not comfortable.
