Most aquarium heaters are preset to 25 Celsius, (78 Fahrenheit,) and that’s the temperature that an average tropical aquarium should be.
The vast majority of tropical fish we keep are fine at that temperature, so many people never alter from the aquarium heater preset temperature.
Adjustable heaters can typically be turned up or down from 20-30 Celsius, (68-86F), enabling the fish tank owner to raise or lower the temperature range to suit the species they keep.
Popular species like the Redline Torpedo Barb, Sahyadria denisonii are best when kept in water from 20-25C, (68-78F) whereas Discus need much higher temperatures, with 28C, (84F) being optimum temperature.
Tropical aquarium fish can then be further divided into those that like it in the low 20s, mid-20s and high 20s Celsius.
If you keep Discus, Cardinal Tetras, Rams or Zebra Plecs you will need to raise the temperature in order for them to be happy.
A lowering of temperature may be needed for some tropical fish to simulate the coming of the rains and the breeding season, whereas, for goldfish, a rise in temperature is necessary to trigger breeding.
Raising the water temperature to 28 or 30 Celsius, (84-86F) can speed up and disrupt the lifecycle of the Whitespot parasite, so if your fish have Whitespot but can tolerate those temperatures (like Clown loach,) turn the temperature up to help fight the disease.
Tropical fish inhabit waters that are above 20 Celsius, (68 Fahrenheit) year-round.

Above: In cooler waters ( 22 to 26 C / 72 to 79 F ) Bucephalandra grow markedly better and mosses display richer, greener tones.
Temperature plays a powerful, silent role in planted aquariums.
While most tropical plants can survive in water temperatures above 30C / 86F, most tend to show better form and colour at lower temperatures.
The sweet spot for most tanks is between 22 and 26C / 72 and 79F.
We keep most of our tanks at 24 C / 75 F.
Above: sensitive plant species such as Hygrophila sp. Chai (above) and Eriocaulons stunt / melt more easily in warmer waters (above 26C / 79F).
Above 26C /79F it is also slightly less easy to saturate the water with CO2, as the solubility of the gas decreases as the water temperature rises.
The sweet spot for most tanks lie in between ( 22 to 26 C / 72 to 79 F).
This contributes to tank stability, and brings out the best form and coloration in most ornamental aquatic species.
While tropical plants can survive below 20C /68F, most species will experience significantly slower growth at these temperatures.

Most of the fish species that are typically found in an ordinary home or business aquarium will usually do well at tank water temperatures of 24 – 26.5°C (75°-80°F).
This will be true for the vast majority of tropical fish types, and this temperature range will also be a good starting point for most freshwater fish species normally kept in fish tanks.
There will be some differences in tropical fish tank temperature ranges depending on each fish and what they are most used to when living in the wild waters where they originated.
For example, goldfish have been known to live in waters that are anywhere from 4.5°-25.5°C (40°-78°F).
Most goldfish that people purchase for their aquariums will not be used to such an extreme range of temperature settings.
Fish experts recommend using a fish tank thermometer and setting the water temperature at 18°-22°C (65°-72°F).
Consider this list of ideal tropical fish tank temperature settings for some of the most common aquarium fish species.
Guppies: 22°-26°C (72°-79°F)
Bettas: 24°- 27°C (76°-81°F)
Try for Steady 79°-80°F
Goldfish: 18°-22°C (65°-72°F)
Tetra Fish: 22°-25.5°C (72°-78°F)
Molly Fish: 25°-27.75°C (77°-82°F)
Clownfish: 22°-25.5°C (72°-78°F)
Platy Fish: 24°-25.5°C (75°-78°F)
Killifish: 22°-34°C (72°-75°F)
Gobies: 24°- 27.75°C (75°-82°F)
Aim for 26.5°C 80°F
Rainbow Fish: 23°-25.5°C (74°-78°F)
Discus Fish: 27.75°-30°C (82°-86°F)
Angelfish: 24°-29°C (75°-84°F)
Catfish: 22°-27.75°C (72°-82°F)
Gouramis Fish: 24°-36.5°C (75°-80°F)
Oscar Fish: 24°-26.5°C (75°-80°F)
Some fish will require a bit more TLC and precise temperature monitoring.
This includes the ever popular betta fish.
People love bettas for their gorgeous fins and tails that flutter delicately through the water.
These fish generally don’t do well with certain fish species, and even a slight change in their environment, including temperature shifts, can stress them out and make them sick.

Tropical fish, for example, do best between 75° and 80°F. Fish are cold-blooded – aka ectothermic or poikilothermic – animals, meaning they cannot control their body temperature. Instead, they rely on the temperature of their environment to regulate their metabolisms and activity levels. Always set your heater for the middle of your fishes' preferred temperature range and choose fish that share the same temperature requirements. Maintaining a stable temperature that matches your fishes' needs isn't difficult, and your fish will thank you for it. Fish that are kept at the wrong temperature long-term may not grow as large, their colors may be muted, they may be less inclined to breed, and they may not live as long. Making matters worse, above 90°F, the beneficial bacteria that maintain balance in an aquarium begin to die, creating the potential for dangerous ammonia and nitrite spikes.

The ideal temperature for the majority of tropical fish tanks is between 25° to 27°C (76º to 80ºF).
You can purchase a stick-on thermometer that is able to be mounted on the side of the tank.
You may, therefore, check the temperature whenever you pass by.
We need to keep in mind that the outside environment can have an impact on the temperature of your fish tank.
This is why heaters may sometimes be necessary during the colder months of the year in order to maintain the proper temperature range.
During hotter months, it is critical to keep your aquarium from overheating.
The water will, therefore, need to be circulated more vigorously.
Not only will moving currents enable your fish to obtain more oxygen, but they increase rates of evaporation.
This helps to cool the water so that it is maintained within the range mentioned above.

A good range is 76° to 80°F (25° to 27°C). A few species need to be kept several degrees warmer, and some species require temperatures a few degrees cooler. For tropical fishes a reliable heater is necessary, at least during the colder months of the year. The water temperature should be stable. Most experts today recommend 80°F as the optimum temperature for corals, although older sources unadvisedly recommended lower temperatures.
