Clownfish can thrive in cool water, so long as their temperature ranges from 75 degrees F to 80 degrees F. You don’t need to keep the water in your tank at a particular temperature. In fact, the only range that is important is the one you have set on your pool heater/cooler.

While it may seem pointless to try and keep the water temperature in a marine aquarium controlled, there are significant benefits that make it worth doing so. For example, while a heater can help maintain the desired water temperature standards for you and your fish, they do not exist out in nature, meaning wild-caught animals have never lived in conditions high.

Some people believe that clownfish can survive fluctuating temperatures in an aquarium because they already experience similar fluctuations in the wild. But since the water bodies that clownfish inhabit in the wild cover so much vast area, even when swings in temperature occur, these changes are moderate and slow. Some changes in temperature take a long time to be noticeable. But for aquariums, because the volume of water is so low, any fluctuations are sudden and extreme.

It is crucial to know the temperature requirements of your clownfish and to keep it within that range.

What Affects Clownfish Tank Temperature?

The location

There are many aspects to consider when choosing the location of an aquarium. One factor is the temperature difference from your domicile, as it will affect water quality in various ways and extend or shorten its life.

Even with a heater, direct sunlight will cause the temperature to spike in your saltwater tank- it is especially prevalent in summer. Conversely, if the window is open during winter, temperatures can drop too low and kill fish.

Artificial lighting

Fish owners can best place their tanks out of direct sunlight to stay away from radiators, vents, and diffused light.

Most homeowners are not aware of the connection between artificial light and water temperature. Incandescent bulbs and other hot lights can drastically increase the temps in your small tank.

Lighting can have a significant impact on temperature, but it is easy to over or under-estimate the magnitude of this effect.

Water replacements

And you affect the temperature when changing the water in your aquarium. When making a major shift, always test for pH levels to ensure that they are still within range.

Low-quality equipment

It’s hard to know about this question. Sometimes the temperature in your tanks can fluctuate because there are issues with your equipment. For example, an issue with your thermostat may mean that it displays the wrong temperature, and this could lead to fluctuations in temperature too. It also might be possible for heating to fail to cause fluctuations in heat.

There are plenty of stories online about tanks that were overheated because the heaters got stuck in the wrong setting. It is imperative to have proper temperature control equipment, but you should also examine your fish’s behavior to assess if it is comfortable. Their endurance will tell you whether or not the water conditions are appropriate.
