Goldfish are freshwater fish originally from Eastern Asia. They’re surprisingly tolerant and can be kept in many types of water conditions, but some need a bit more care than others. If you’re keeping your goldfish at home in an aquarium, it is vital that you maintain their water temperature to make sure they stay healthy!
Goldfish require a water temperature between 65-75°F to thrive. Goldfish can withstand cooler temperatures, but their body temperatures drop gradually as the water cools. This is bad for fish health and can decrease their lifespan.
To keep your goldfish from getting too cold in winter, it’s a good idea to keep them in a heated aquarium with a heater that maintains room temperature above 65°F. Goldfish can adapt to cooler water conditions by reducing oxygen saturation levels (which decreases metabolic rate), hiding in burrows, being inactive or resting and going without food.
Goldfish will show signs of stress if kept at a water temperature that is too low, but they are more likely to thrive at cooler temperatures than other fish are. Goldfish are very hardy, but you should still keep an eye on them to make sure they’re coping with the temperature change.

Temperature range of Goldfish water
The temperature of the water should be kept between 65-75°F. Goldfish are more active at higher temperatures, and they will also become less active and more lethargic at lower temperatures.
Goldfish need cooler water for a few reasons:
To stay healthy. A low temperature is important for they’re swimming muscles to operate efficiently and thus keep them happy (and make them want to eat the food). To avoid growth. Fish grows faster in warmer water, so keeping the water cooler allows it to grow slower.
Fish grows faster in warmer water, so keeping the water cooler allows it to grow slower. To avoid stress. Goldfish can’t tolerate temperatures below 60°F.
What else is important?
Some goldfish prefer to be kept in water with a pH of under 7.0, while others prefer it to be above 7.5. Goldfish require a specific amount of dissolved oxygen in their water to breathe properly, and they will die if there isn’t enough oxygen in their water or if the temperature is too low (if the temperature is too high, they will die from lack of oxygen).
Goldfish that are kept in water with a pH level above 7.5 and an oxygen level below 3ppm will be more susceptible to disease and may not eat well. Goldfish need a lot of oxygen to stay healthy, so it is important to make sure their water has enough dissolved oxygen.
Goldfish will live happily at different temperatures at different stages of their life, but generally speaking it’s best to keep your goldfish between 65-75°F for optimal health and growth.
What temperature is best for goldfish?
Goldfish will thrive at room temperature between 65-75°F. Goldfish shouldn’t be kept in a tank that is too cold (below 60°F) or too warm (above 80°F).
The ideal water temperature depends on when the fish is active, what size the fish is and its body mass.
If your goldfish is active at night, a temperature that ranges between 65-75°F will be ideal. If your goldfish is active during the day, it should be kept at a temperature that ranges between 70-85°F. The optimal temperature for food consumption and waste digestion is around 74°F, but goldfish can digest food at a range of temperatures (between 10-85°F) and still remain healthy.
Is the water temperature too high or too low?
Goldfish prefer to be kept at temperatures between 65-75°F, but they will survive slightly colder (below 60°F) and slightly warmer (above 80°F) temperatures. The ideal water temperature will depend on when the fish is active, what size you’ve got and its body mass.
When maintain the right temperature, goldfish will have the best appetite and will be able to achieve a healthy body weight. This is especially important for small goldfish as it makes them more susceptible to disease.
How do you maintain a high water temperature?
You can keep the tank’s temperature at 60°F or higher using regular heat lamps or an aquarium heater, which is best suited for keeping small fish. There are also models designed specifically for aquariums that can be bought at your local pet shop.
How do you keep the temperature low?
If you’re looking to keep your goldfish at room temperature (around 65°F), a good aquarium heater is a must. You can also use a DIY heater made out of heat pads, which are about $20-30 (just like buying an aquarium heater). If the water in your aquarium is too warm, use a cooling device such as an air conditioner or ice blocks to cool it down.
How do you know if the water is too cold?
Goldfish will feel stressed when the temperature drops below 60°F, causing them to be lethargic and eat less. They will also show signs of stress if kept at temperatures below 70°F, which can include a lack of appetite and irregular sleeping patterns. If you are noticing these symptoms in your goldfish, it’s important to make sure their temperature is right for their personal preferences.
How do you know if the water is too warm?
Goldfish will feel stressed when the temperature increases above 80°F, causing them to be lethargic and eat less. They will also show signs of stress if kept at temperatures of 90-100°F, which can include a lack of appetite and irregular sleeping patterns. If you are noticing these symptoms in your goldfish, it’s important to make sure their temperature is right for their personal preferences.
How do you know if the temperature is too high?
Goldfish will feel stressed when the temperature increases above 80°F, causing them to be lethargic and evict less. They will also show signs of stress if kept at temperatures of 90-100°F, which can include a lack of appetite and irregular sleeping patterns. If you are noticing these symptoms in your goldfish, it’s important to make sure their temperature is right for their personal preferences.
How do you know if the temperature is too low?
Goldfish will feel stressed when the temperature drops below 60°F, causing them to be lethargic and eat less. They will also show signs of stress if kept at temperatures below 65°F, which can include a lack of appetite and irregular sleeping patterns. If you are noticing these symptoms in your goldfish, it’s important to make sure their temperature is right for their personal preferences.
How do you know if the temperature is correct?
You can use a thermometer to make sure the temperature is correct. The ideal water temperature for goldfish will be between 65-75°F, but it will vary depending on the size of the fish and how active they are. You should also take into account the room temperature; if you keep your aquarium in a hot room (over 85°F), it’s important to reduce the temperature inside your tank as it can cause stress.
Do goldfish like cold water or warm water?
Goldfish like cool temperatures, but they require warmer water to digest food. Goldfish prefer to be kept at temperatures between 65-75°F, but they will survive slightly colder (below 60°F) and slightly warmer (above 80°F). The ideal water temperature will depend on when the fish is active, what size you’ve got and its body mass.
Do goldfish like hot water or cold water?
Goldfish don’t need hot water to survive, but they do prefer warmer temperatures than cool ones. They can survive slightly cooler (below 60°F) and slightly warmer (above 80°F) temperatures. The temperature that they prefer will depend on when the fish is active, what size the fish is and its body mass.
Do goldfish like room temperature or cold water?
Goldfish like cool temperatures, but they require warmer water to digest food. Goldfish prefer to be kept at temperatures between 65-75°F, but they will survive slightly colder (below 60°F) and slightly warmer (above 80°F). The ideal water temperature will depend on when the fish is active, what size you’ve got and its body mass.
