Monitoring the temperature of your goldfish tank How to measure tank temperature. To measure your tank temperature you will need to purchase an aquarium thermometer [BUY NOW] and follow the instructions. As you can see on Amazon, there are types of thermometer that stick to the inside your tank and types that stick to the outside of your tank.. We prefer the ones that go inside and float in ...


The best temperature range for most Goldfish is sixty-eight to seventy-five degrees, and some breeds prefer even warmer temperatures. So, what is the ideal Goldfish water temperature for you? Goldfish are exothermic, like all fish. Their body temperature is determined by the temperature of the water.


The ideal temperature for a goldfish tank also depends heavily on the type of fish involved. For example, common goldfish are generally one of the hardiest variant and most can survive in cooler waters as long as the water is not frozen. At the other extreme, some goldfish may survive the summer heat where water temperatures reach as high as 85 ...


However, some fancy goldfish are not as hardy as some less showy relatives and stability is the name of the game, so avoid placing tanks near radiators or in direct sunlight. If keeping fancy goldfish outside you will have far less control over temperatures but, in my experience, this has no adverse effects.


Start by slowly lowering the aquarium water temperature (no more than 2ºF per hour). Your ending “winter” temperature should read between 50ºF and 55ºF. If you allow your goldfish aquarium water temperature to become any lower than that, it can cause your goldfish to go into shock as well as become inactive.


Goldfish, like most fish, seem more sensitive to wide and rapid temperature fluctuations. They can adapt to fairly consistent conditions — even if extreme — readily. Given that your goldfish aquarium is operating at the upper end of the temperature tolerance range for fancy goldfish, I would recommend strong supplementary aeration.


Their ideal tank temperature would be around 65-70F. They can tolerate up to 74-75F but warmer than that will cause them harm in the long term. ... Unlike tropical fish, goldfish enjoy cold water ...


Goldfish come from colder, northern, waters. By my standards their temperature range is just under what I put tropical fish at. I put most tropical fish between 75-85F(roughly 23-29.5C), whereas I put both goldfish and koi at 65-72F(roughly 18-22C).


Temperatures for goldfish are a surprisingly complex issue. Goldfish are technically cold-water fish. However, just because goldfish can survive a wide range of temperatures does not mean they are healthy or happy at those temperatures. Goldfish in the wild, so to speak, can survive temperature ranges of forty to one hundred six degrees.


To keep a goldfish alive, keep it in a tank that can hold at least 10 gallons of water so it has plenty of space to swim around. Additionally, use a filter that’s rated for your tank size in order to keep the water clean.
