I'm pretty sure being in water that is too hot or too cold can kill them. but when its hotter or colder than usual, they simply have a harder time moving around. their body movement slows down.
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.
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.
it depends on what type of fish.a goldfish has to be in room temperature water.
They start to come into breeding "mode" when the temperature gets over 65F.
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.
There is no such thing as a 'Tropical Goldfish'. Goldfish are a coldwater species. Their prefered temperature is above 50F and below 65F. The fish respond to a slow rise in temperature over a week or so from around 65F to about 70F during Spring/Summer by spawning.
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.
