Hello, , Im sorry this isnt a "Tropical" Freshwater fish, but i was wondering if i can keep them in a totally unheated tank? At night in the winter it drops down to 40 in my house (Not the tank water). Will they be ok? Thanks )
I've known people to keep them in with a heater set for 69 degrees...that way it won't drop too far down. From what I understand, it's also the easiest way...hope that helps!
Im no expert on goldifish but they prefer temps around 68 degrees. However I think they can stand temperatures a few degrees above freezing for short periods of time but im not sure. I know alot of people that keep goldfish in ponds outside and during the winter it can get extremely cold so I would say yes for short periods of time.
But I would wait until someone more experienced responds.
For fancy goldfish, 68 degrees Fahrenheit is the lowest I would allow. They are more intolerant to temperature extremities compared to singletails. Fancies prefer their temperature a tad warmer. 72-78 degrees Fahrenheit is quite appropriate. If your room temperature falls below 68, get heaters. Keep the heaters in turbulent areas to distribute the heat evenly. Allow 3-4 watts per gallon total based on the room temperature you have.
OMG THATS FREAKEN COOOOOOLD!!!!!!! My house never goes below 65!
