Tropical fish – the kind you can buy at the store – are most comfortable between 75 to 80 degrees Fahrenheit (24 to 27 degrees Celsius). Cool water fish, like goldfish and koi, need water that’s much cooler than that – between 60 and 75 degrees F (15 and 24 C) or even colder.
How do I know if my fish tank is too hot?
The first sign of stress to your fish during hot weather is rapid gill movement or gasping for air at the surface. Corals and anemones will close up and their polyps or tentacles will retract. Algae growth may increase, and the water may begin to turn cloudy due to a bloom of heterotrophic bacteria.
Cool water fish do better in temperatures below that, usually between 60° and 75°F (15-24°C), but some of them enjoy water well below 70°F, which is not suitable for any tropical fish. Ultimately the best temperature will depend on the species of fish in the aquarium.

How do you check a fish tank temperature without a thermometer?
How can I heat up my fish tank faster?
Using a hot water bottle is another practice that can be used to heat the water inside a fish tank quickly.

Will a heater hurt my fish?

Do You Leave the Aquarium Heater on All the Time? Yes, you can leave the heater on 24/7. Aquarium heaters have an internal thermostat that turns off the heat when it reaches a specific temperature, thus keeping the water temperature within a few degrees of the desired setting.
Do fish tank heaters raise electric bill?
Power consumption depends not on the size of the fish tank, but on the electrical equipment that it’s running, and how long it’s on for. If it’s a tropical tank, energy consumption will come from the heater, the light, and the filter.
Do fish tank filters need to be on all the time?
It is not a good idea to turn off your aquarium filter every night. The filter plays a key role in the health of your tank, and shutting it down for hours at a time can eventually lead to problems.

Fish tanks do use a lot of energy, between pumps, lights, and heaters, it’s no surprise they are costly to run. However there are ways to cheapen their usage somewhat. The lighting, which accounts for around 45pc of the total bill, does not need to be on all the time, provided your tank has access to natural light.
Do fish tanks really need heaters?
If you are keeping tropical fish, you will need a heater. A heater insures that a tank doesn’t get too cool, and that the temperature stays steady during the course of the day, even when the room cools off (e.g., at night). For many tropical fish, a temperature of 78F is ideal.
I have had fish such as guppies and neon tetras that were able to survive for a couple days without a heater. It really depends on the fish. As for the filter, I think they should be capable of surviving for 12 hours without one.
