Fluctuating water temps - is this bad?
I bought a thermometer recently for my tank and noticed when it put it in that the water was reading 17 degrees C.
It's a small 38 litre freshwater tank with one very small Oranda living in it.
I've noticed today that the temp is nearly 20 degrees C and earlier in the week it was down to just below 16 degrees C.
I know the tank is not ideally placed and I've got a much bigger tank and tank location for her to move into but what sort of temps should I be aiming for and variations are considered acceptable?
These variations are small and happy over several hours, so it gives the fish time to adjust.
For the new tank, even though she's a goldfish, I'd pick up a heater and set it to a good temperature just so it doesn't drop so low. Fancy goldfish are more sensitive that common goldfish and actually should be at at least 20C to be comfortable.
Excellent thank you so much for that!!
How big is the much bigger tank?
I agree, if that is the tanks unheated temp then you should get a heater to set a minimum temp.
The temp fluctuations are largest in small volumes of water. The temperature will be much more stable in a larger tank.
The new tank is 153 litres / 40 Gal
Thank you very much
That will be a nice upgrade for the fish for sure. Down the road you might find the fish needs one last upgrade, though. Depends on how well you take care of it ;)
Yup. Oranda are one of the bigger fancy types. I think they can hit 10 inches.
