Simply put, they will die. Goldfish are coldwater fish and if their water gets too warm, their metabolism speeds up. Their bodies then demand more oxygen for them to survive. The warmer water is, the less oxygen it can contain, so coldwater fish simple die from lack of oxygen in warm water.
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.
Unchlorinated water, such as bottled distilled water is best.
The water should be at room temperature.
Algae in a goldfish pond is quite common with an increase in sun (light) and temperature. To try and keep algae to a minimum you will want to look at ways to provide the pond with shade, and regularly change out some of the water for fresh water during the warmer months.
The temperature increase and the motion of molecules is accelerated.
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.
well, not long. i had a goldfish and it died in like 8 hours.
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.
