Do Goldfish Need a Water Heater? Yes! - Ideal Temp for Fancy Goldfish

To buy the water heater I recommend check out my recommended products on my website!

In Winter I use heater, summer they are all outdoors in tubs...my fry always have heater. Good information.

The optimum temperature for fancy goldfish is 68° to 74° F, while comets and shubunkins should be kept between 60° and 70°F. pH is not critical, but ideally should be between 7.0 and 8.4. Rapid changes in temperature or water chemistry can be harmful, if not fatal to goldfish.

I’m amazed seeing all your knowledge and love about those fluffy cute babies! I’m new in the goldfish hobby besides my other 3 tanks of tropical freshwater fish, and I’m loving it. My fancy goldies seem to love 76F. I’m following ALL your instructions in many of your videos! I became your fan! Thank you SO MUCH for sharing your “gold”!

You should write a goldfish guide, any kind of book, your knowledge is just wow

I have a goldfish I’m pet sitting, at first I had him at 62-64° (room temperature) he has doing pretty good. The issue I noticed with cold water is that it prevented the aquarium from cycling and I was seeing a lot of problems with brown algae and green cloudy water [ during this time I used Fritz 7 and Seachem Prime and Stability] nothing worked. I finally decided to bring the up the temperature to 73° and ✨. Test results finally came up 0ppm, 0ppm and detectable Nitrates 🙌🏼…. I still struggle with a little bit of cloudy water, but I’m assuming I still need to build up more bio filtration it’s still a new set up almost 2 months.

Nice explanation. I find that 75F for indoor Ranchus works very well. Thanks for including the temp vs. O2 relationship. I find 75F is a nice tradeoff.

Thank you for this! I got a lot of stick from goldie keepers for keeping a heater for my goldfish. I have a lot of air going through anyway and he is doing so well and looks to be thriving! Glad to know I’m not being ‘cruel’ as I was originally told 😂 thank you :)

Hi Luke,

I live on a narrowboat in the U.K. and keep two Ranchu and an Oranda Nymph in a blagdon affinity pond on the front deck.
In the winter their water temperatures can drop to below 6C or 40F. Although I don’t feed them at these temperatures, I do feed them whenever it goes up to 10C.
They are not U.K. bred fish, they are store bought, I believe they originally came from Thailand. They were originally stocked during the summer months and fed on Hikari Oranda Gold, to fatten them up to endure the winter.
Filtration is just a large box filter and a large sponge fed by a tiny usb air pump.
Weekly maintenance is a gravel vac, 50% water change and monthly clean of the box filter and rinse of the sponge.
In the countries these fish originally came from, ie China and Japan, winter temperatures regularly drop below zero C and although mine were bred in Thailand their original genes allow them to withstand the low temperatures providing they are fat enough before entering the winter period.
As far as health is concerned within eighteenth months they have gone from the size of marbles to tennis balls and no sign of swim bladder problems so far.
I also keep two fancies inside the boat and in the winter their water temperature can vary between 7C and 20C in a 24 hour period and they are just as healthy, in fact they spawned in a 100 litre aquarium, same maintenance program and just a sponge filter for filtration.
It just goes to show how tough these fancy goldfish can be !
I don’t disagree with anything you’ve said in this video and and think your fish are super healthy and loved.
Thank you for sharing your fish keeping experiences, I love your enthusiasm.

Regards Warren 🇬🇧

Here in Philippines other breeders don't need heater because there's no winter in our country all our problem was heavy rain

[Amanda-ckno]

Great video, this is the information I find to be super helpful and should be spread throughout the community. I keep a variety of different fish but find this info. To be applicable to the kinds I personally keep 😀 I want them to be big, colorful, healthy and full of personality!

luke Hello my friend. How are you? I am a goldfish like you, but I have 2 Thai black appointments in my 35 liter aquarium. I am, all Japanese are wonderful here. I send my greetings to you from Turkey, brother.Why does this shedding phenomenon, man, how can it prevent it and people like us, I wonder if they shed their new colors with scales.

I have 8 goldfish in my 50 gallon tank and i set my heater at 29 degrees and they are healthy and fine.

[adkgaladkgal]

This is so helpful, thank you. I enjoy watching Brand and Bubba, thank you

I am so excited now I can bring my tank to 75f 👌 I always heard they r cold water fish and that's it… but I want plants and snails in my tank and I want everybody to grow faster and snails and plants to me to be happier… now, why r u goldfish in just a tank with no plants or even a background… I heard they eat the plants? Which is good? Idk ty for helping me and ur knowledge!

[elibetsaldivar]

Can you do a 100% water change video next 😭. I recently saw your recommended products for a tank with fancy goldfish and would like to see how you use them on your tank! I have a fantail, a red cap oranda, and an oranda goldfish and we love your videos ☺️

[Lukksia]

in my personal opinion i think some people don’t need it, my room is about 75 degrees and my water at room temperature is 72, i don’t have goldfish but i do have a community tank with tropical fish and they are thriving, so while yea if your house is cold you probably need one but if your house is like mine your probably good without it unless you have discus or something like that

[colleenanne]

Great info! How slowly should you increase the water temperature? We have a 10-year-old common goldfish that has been struggling with positive buoyancy issues - now treating with kanaplex and metafix. Has been at room temperature all seven years we've had her which fluctuates between 69 to 71°F depending on winter to summer. Is 1*F per day too fast? I am thinking around 74-76F for her. She has the one side of her belly slightly swollen. Presumed to be fluid retention so also doing twice daily epsom salt baths.
