Goldfish are best kept at a temperature of at least 74F to 76F. There are times that you might increase the temperature to a tropical fish level for a short term to treat an illness, but you should not have it too warm.
Goldfish are ectothermic animals, meaning they cannot regulate their body temperature internally like mammals. Instead, their body temperature fluctuates with the surrounding water temperature. As the water temperature changes, goldfish adjust their metabolic processes accordingly, but they do not maintain a constant body temperature.
Unchlorinated water, such as bottled distilled water is best.
The water should be at room temperature.
If it is a small goldfish, it will physically fit in something that small. But, it will not live very long in it. If you wish to keep goldfish alive, you need at least ten gallons of water for each goldfish along with a good filter and a heater to keep the water temperature stable. With proper care goldfish can easily live 15+ years.
Goldfish spawn in groups in springtime when the water temperature approaches 70F. They do not have live babies.
Just leave the aquarium at room temperature.
You should keep the water at room temperature.
Goldfish are meant to live in cold water, not the warm water in a tropical aquarium. This is a huge reason why goldfish and tropicals shouldn't be in the same tank.
well, not long. i had a goldfish and it died in like 8 hours.
Since goldfish are coldwater fish they require an aquarium with cold water. The temperature should not exceed 75 degrees F or be lower than 55 degrees F. Any temperature in that range should be just fine for goldfish.
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.
