trying to match the tanks water temp during a water change is the best choice, but, what if u had to choose a little warmer or a littler colder?

what would u pick and why?
 
colder

When in the wild and there are rain storms, the rain is never hotter than lake,river,streams temperature.

At night the temperature allways drops no matter where you are.

I have read about in amazonia that during the rainy season the water temps would drop 10-12 degree's. And that is what sets off the breeding in most species.

And in the wild there is nothing that would cause a fast or instant temp increase.
 
I have two tanks running. I have a 75 gallon in my basement where the ambient temp is always cooler. The tank runs at about 76-78, so I try to err slightly to the warm side.

I have a 30 gallon tank upstairs where the ambient temp is much warmer. In the summer the tank temp runs at about 80-82 so I try to err on the cooler side. In the winter I adjust as needed.

Hot water has no oxygen. Always colder.

ever swam in a lake or river? some spots are just warmer... it the amount of sunlight and depth of the water, i think we dont give our fish anywhere near enough credit on how much temperature change they can handle

so i voted bacon
 
i always choose colder but i have temperate and coldwater fish. if they were tropical i would choose warmer. as its more comfortable to get into a warmer then body temperature shower then a colder one. this is excluding very hot water
 
i use colder water, its more efficient to heat the water up. Using warmer water can shock fish, and plants.

I agree 100%

I do not use any hot water when doing my weekly 500+ gallons of water changes. Except in the dead of winter and thats because I have shocked a tank before and killed off a few fish.
 
hmmm..most older fish books I have seen always recommend that warmer is better than colder.

cold water slows down metabolism and can shock fish more than warm water varying by the same degree.

ie 4 degrees colder is worse on the fish than 4 degrees warmer..

in other words, if you cant match exactly you are better to add water a little warmer rather than colder.

I have always done this. a bit warmer works fine.
