Happy new year and Merry Christmas from Canada (Québec). I live in a cold country, so I am wondering how type of container and length for keeping ranchu outside in winter with -20 degree celsius temperature. Do it possible or not?
Hi Melissa, Merry Christmas! It is impossible to just keep them in an outside pond or tank at -20C in Québec. You need to keep them in a greenhouse room or your garage (if you add full-spectrum LED light) with airstones. Just don't simply keep them in an AC room at 25C, goldfish need low temp.
Lei, I just watched your other earlier video on feeding in winter … should have watched it BEFORE this video as much of the information I was looking for on water quality monitoring is found here .., sorry about jumping the gun.
I have a fantail and a lionhead in my basement and have a heater to keep the water around 60°F. they are still pretty active and like to eat. I guess I should reduce feeding. They've gone down to 40°F before but I'm worried about it getting too cold if I turn off the heater
Depending on your goal about these lionhead. If you just want to keep and make them grow fast and big, yes, you may use a heater. If you want to breed them, please let them experience some coldness. 40F should be perfect for them. Wheat germs food, please. Trust me, I got a season via my blue egg phoenix goldfish. Their spawning behavior faded away and eventually stopped after 2-3 years of residence in my AC room (25C).
This is my first year keeping goldfish in a pond, thank you for this video! I am curious, I live in the northern part of the us and it gets very cold here. I was advised by others to use and airstone to keep the surface of the water from freezing, but I see in this video it is frozen solid! Which is best? Thank you and happy holidays!
Congrats, my friend. Outdoor pond is the right and easy way to keep goldfish. I would keep airstones in my outdoor tank to slow down the freezing. It is OK to have a thin layer of surface ice, but make sure don’t get the whole pond frozen. Also your goldfish will be in a state of hibernation. They swim slow and digest slow. No need to feed them when water temperature below 10C. If water temp is above 15C, you may feed a little wheat germ food once a day.
Does this apply for indoor aquariums? Right now heater with temperature controller is set up to maintain stable 73F. Would it be better for them to go through the temperature swings at night?
Yes, in general. Burly gradually remove your heater, first lower the temp setting to 68F for a few days then 65F, and then remove it completely. There are a few cases that you want to leave a heater in your tank. I will highlight them next time.
Hi Lei! Really enjoying your channel and as a new hobbiest I’m learning lots. I’m wondering if you can highlight your own tanks and what goldfish you currently are keeping. Merry Christmas!
Great informative video. Thank you so much. I’ve recently found your channel and working my way through all your videos. Thanks for the amazing content and sharing your knowledge 👍🏼
Hi Lei, happy holidays. My concern is not cold weather but daily temperature fluctuations in California. When I kept my fish in garage, during fall, when temperature ranged from 60f to 90f, one developed ich and since then I have added a heater to keep temperature stable after the high temperature treatment. Another issue is when I was a child in northern China, I had a blue Oranda, which developed fungus in a cold winter and when slow metabolism kicked in. I wonder if it is due to the fish not moving much. Right now, I am keeping temperature of 69f or 19c while the room temperature is 63f and still feed them as usual. They are active and love eating. Should I reduce the heater temperature more to save some energy and water evaporation? :D
Hi Jerry, thank you for sharing your experience. Great info. Did you use green water during the winter? The green water may reduce the chance of fungus issue. If you put outdoor, a greenhouse room should a better choice than direct outdoor.
Merry X-Mass. Would it be better to unplug the heater in the goldfish tank and let the aquarium temperature fluctuate? as the house cools down to 60 at night and warms up to 68 F in the daytime. Would it be possible to mail you a check to order your Merch.?
Hi Greg, Merry Christmas! 📌 just pinned your comment. Yes, you can leave your goldfish in the house with natural day/night temp fluctuation. Please keep airstones on. 60-68F is actually perfect for them. Reducing feeding, too. The ranchu mug is a Christmas gift to you. Did you receive it yet? Don't worry about paying me back 🙂ru-vid.comgaming/emoji/7ff574f2/emoji_u1f4cc.png
@@GoldfishCorner I have not received the mug yet, but I only live a few hundred miles from you in Medford Oregon and am not worried, it will be my favorite mug, TY
There could be many reasons to trigger this. How cold is your outdoor temp? What is your feeding schedule? Do you use green water in the tank? Do you feed wheat germ food? Some swim bladder issues could be temporary, so how did you treat yours?
@@GoldfishCorner the problems started by maybe 17°C water temperature in the ponds outside. usually at anything below 20°C i bring the fish in. I feed pellet food and frozen bloodworms etc. i gont use wheat germs because they are very fine food and they don't like to eat it too much. regarding swimbladder treatment, i take the fish in, rais the temperature and use an antibiotic called borgal. The active substances of this antibiotic are called: Sulfadoxinum and Trimethoprimum. Actually i didnt manage to heal one fish with that treatment. i tried also yellow powder and other medicine. nothing helped. i never healed one fish. all suffered and i had to end their suffering or they died by themselves. Maybe you have a better idea of treating swim bladder issues. i tried so much, also swimbladder issues after shipment i tried to treat. nothing ever helped.
I recently bought a group of Thai ranchu and I would like to keep them outside in a greenhouse pond, but the seller told me they must be kept hot like discus (84-86 f) all year. Is it possible to acclimate them to temperate conditions or is it true that they must always be hot?
Lei, As always another informative and thorough examination on an issue of concern for our favourite special animal! Awesome job … It will come as no surprise that I have a question … well an observation and a question. Throughout the presentation you had video of goldfish kept in the traditional way - outside in large Chinese ceramic pots . The season is obviously winter as there is a not so thin layer of crystal clear ice over the entire surface of the pot. The carpet of green algae is clearly visible on the bottom and the fish can be seen resting (in torpor) and in some cases swimming but definitely at a much lower level of activity. Given that it’s winter, ice covers the entire surface and will thicken as winter deepens - my question concerns how to monitor the water quality for things like pH etc. Is it even necessary over the winter given the low level of fish activity and much lower levels of foraging on the carpet algae hence less build up of ammonia etc? If it is still necessary how would one go about doing water changes etc? and how often? I guess that is more than one question … Again, Happy Holidays to you and your Bruce
