Will My Fish Be Okay Without A Heater For A Day?

A tropical fish could last a day or 2 without a fish tank heater and in a water temperature that is below 40°F.

The fact is, your tropical fish will not be okay without a heater for a day.

If you are talking about survival, yes they will survive, but if you are talking about being okay, I highly doubt it.

This is because all tropical fish requires a water temperature that is between 68 to 80°F and when such is not in place, they could have many health issues which could lead to their death.

Again, it depends on the nature of your fish.

If you are talking about non-tropical fish such as many species of marine fish, then they will be okay without a heater, but if it is a tropical fish, whether marine or freshwater, then it could be very risky keeping them for a day without a heater.

We all understand that your heater may break down at any time, so I usually recommend buying at least 2 Heaters and keeping one for emergency times.

Conclusion

Aquarium Heater could kill fish, so you should invest in a quality heater to avoid having issues with your heater and getting your fish and other animals in your tank killed.
