They live in ponds, streams, and rivers in places with a temperate or tropical climate. Although goldfish live in cold water and need lower temperatures than tropical fish, they cannot live in very cold water. The ideal temperature for goldfish is 65°F to 72°F.
How do fish act when water is too cold?
Water that is too warm or too cool becomes uncomfortable. In the wild, a cold fish would simply swim to warmer water. If the water in your tank is too cold, then your fish’s metabolism will slow down, which leads to your fish becoming sluggish and sleepy.
Do goldfish need warm water?
Goldfish Water Requirements Considered cold water fish, goldfish can also be kept in heated aquariums. The optimum temperature for fancy goldfish is 68° to 74° F, while comets and shubunkins should be kept between 60° and 70°F. Rapid changes in temperature or water chemistry can be harmful, if not fatal to goldfish.
What is the lowest temperature a goldfish can live in?
Goldfish and koi are very hardy fishes; they can survive water temperatures as low as 0°C, which means they can survive in the pond during the winter as long as it doesn’t freeze solid and they have adequate water quality and oxygen.
Why do goldfish die after changing water?
Did the water change kill the fish? Because the fish live in the water, and the changes happen slowly, they adjust to it. When a sudden, large water change occurs, it causes such a drastic shift in the makeup of the water that the fish often cannot tolerate it and they die.
Can goldfish survive in tap water?
Can a goldfish live in tap water? Goldfish cannot live in untreated water straight from the tap. This is because tap water contains chemicals that are bad for your fish. And, even worse, can kill all of the ‘good bacteria’ in your tank.
How do you know if your fish is cold?
The most common sign of temperature shock is lethargy. Fish are cold-blooded, so unlike mammals who generate their own heat, they can only absorb warmth from the water. When the water is too cold to do this, they’ll often stop moving.
Will my fish die if the water is cold?
Interestingly, cold water is more dense than warm water and can sink to the bottom of the pond. This forces the warmer, lower oxygen water to the surface. So, if we have a cold snap that lowers water temperatures below 55°F, entire populations of these non-native tropical fish will die-off.
What do goldfish like to play with?
Goldfish are known to entertain themselves by playing with aquatic plants and/or finding tunnel-like spots to swim through or into. This is seen as a source of entertainment for them and is a common sight when a goldfish is happy.
Can goldfish live in tap water?
Can goldfish freeze and come back to life?
No, goldfish cannot freeze and come back to life. They will die. There are other fish that can survive after being frozen, but these fish are specifically cold-water fish, and their genetic make-up is very different from goldfish.
How often should I feed my outdoor goldfish in winter?
If the water rises to 90 degrees or above you should stop feeding. In spring and fall when your water temperatures fall to 50-60 degrees, you should reduce feeding to once every 1-2 days and feed a low protein food such as Legacy Cold Weather Food. When the temperatures drop to below 50 degrees stop feeding the fish.
Should you change water after fish died?
Not necessarily if the dead fish is in the tank for a short period of time say 2 to 3 hours. But if it is in it for a long period of time then you should consider changing atleast 50% of the water. Remember never change 100% water since the beneficial bacteria in the water may die off.

Can a goldfish survive without a filter?
A goldfish can live in a bowl without a filter, but not at the optimal quality of life. The bowl with no filter arrangement will likely shorten the goldfish’s life. Aquarium experts recommend that you not keep your goldfish in a bowl, but rather a larger, filtered tank.
Do fish hide when they are dying?
Aquarium fish do not exactly hide because they are dying, but they do hide when they are sick, which could quite easily lead to death, more so if you don’t find them in time.
Why is my fish not swimming but still alive?
