How to get Ideal Temperatures for Your Aquarium




You can spend thousands of dollars on your live aquarium for your pet fish.

But, what if it doesn’t feel alright there?

Just like you need to cover your body in winters and let loose in summers, this species requires special attention, more than your cat and dog.

Your fish feels the cold, and if it looks like it isn’t feeling anything, look again. Unmaintained temperatures of the fish tank or live aquarium will lead to early deaths of fishes. You might place the home aquarium by the window in winters and notice an inconsiderable rise in the temperature, above the demand of the natural habitat, let’s say goldfish.

With the advanced technology, providing the optimized temperature isn’t as much of a challenge now. Invest in some thermometers and keep checking the ambiance inside the fish tank. Your pet fish will enjoy and grow more this way.

Some pet fish owners say that the fish’s slow speed will help determine the home aquarium situation.

If you see the fish going with the flow, it’s probably dead because fishes never go with the flow.

What Is The Ideal Temperature Range For An Aquarium Fish?

Push yourself into keeping a complete note of the amenities behind the changing temperature. Mostly the moderate temperature will range between 75 and 80 Fahrenheit. But it can vary from species to species. If you are looking to attain a long term availability of temperature maintenance, consider it impossible.

No matter how far the technology has evolved, you still need to call a live aquarium specialist or use your knowledge to provide ideal temperatures for the pet fish.

There are idealities behind this procedure that need critical attention later on in the article. But know that the temperature for three types of fishes is as following,

  • Coldwater fish: below 68 Fahrenheit
  • Tropical fish: 75 to 80 Fahrenheit
  • Temperate fish: more than 80 Fahrenheit

Settle Down High Temperature of Home Aquarium

The high temperature in an aquarium means less oxygen.

Start worrying about lowering it down. I will tell you that later in this content. But first, let’s dig into knowing the amenities which provoke high temperature.

  • The thermostat you push inside the home aquarium of the pet fish is broken
  • You haven’t had the time to check the temperature and left the thermostat on
  • More algae because there is no breakdown of it due to less oxygen

The moderate temperature for the fish tank should be below 32 degrees. Otherwise, the gills of the pet fish start to burn. In high temperatures, the fish become more active and start losing energy due to less oxygen. Most commonly, the reason for their death is this. But it may also be due to low temperature.

Prevent Growth of Algae with High Temperatures

You must be thinking the aquarium fish requires a high temperature for living, i.e., below 32 degrees, also the weather for algae growth. Remember, the development of this exclusion is not dependent on temperature only.

Many things affect the visibility of algae in your home aquarium. Here’s how you can prevent it and maintain the temperature at the same time,

  • Decrease the exposure of light into your fish tank
  • Avoid overfeeding the fish since the excessive poop will also lead to the growth of algae
  • Keep changing the water while checking the ambiance inside
  • Clean the aquarium daily and from every corner

Settle Down Low Temperature of Live Aquarium

Make your fish thrive, rather than making it survive. Some fishes cannot withstand lower temperatures. Low temperature makes them sluggish and unable to move freely. This is where the fish starts going with the flow, meaning it is dead. You can increase the temperature by checking the thermostat.

If you have a giant home aquarium, add two to three thermostats alongside a thermometer to keep yourself updated with the temperature fluctuations. Also, remember that the low temperature decreases the metabolism of fish too. In every way, no matter how hard you try, a slight change in the weather will reduce the pet fish‘s lifespan.

Maintain the Ideal Temperature in Your Aquarium

Now you know

  • the causes of hot and cold temperature,
  • moderate temperature for the fish tank,

There are some ways that you don’t have to chase all the amenities for maintaining them. Instead, just a one-time strict check-up for the day will get you all set up for enjoying the exquisite view of beautified aquarium fish.

You win the battle if you keep settled temperatures and there is a lowered rate of pet fish survival to death ratio. Follow these ways to maintain an ideal temperature in your aquarium,

Getting the Basics Right

Basics include the location, size, and construction of the fish tank. The aquarium fish survives more and better in large tanks. But if you have a small size, minimize the count of pet fish.

Also, location matters a lot. If your aquarium is somewhere near the window, it will become hard for you to maintain a cold temperature. Whereas, if it is just below the AC, the warm ambiance is hard to maintain.

With basics, I also mean the construction. Glass fish tank means you need to put only one thermostat inside the water mostly because, in these aquariums, the water stays hot for a long time. Whereas in acrylic, too much might break the glass.

Heating Your Aquarium

Confirm that the thermostats you have inside the home aquarium are working well. Otherwise, it can endanger the life of your pet fish.

Invest a few bucks in the heater, a good one, which is automatic. Once the temperature reaches the set temperature, it automatically turns off, avoiding overheating. The prices are slightly more than the manual ones, but you can see the load it will take off your shoulders.

Cooling Your Aquarium

Once a sage man said,

Where there is calmness, there is a fish.

You want to calm your fishes because they have become super active due to warm water, turn on a fan nearby. The water will start to cool down, and the fishes will start calming down. The divine beauty of pet fish can keep you engaged for a long time.

Testing Water

A larger aquarium means easier to maintain water pH. But if you have a smaller sized home aquarium, it is also easy to maintain, requiring a little more attention.

Why do we need to test the water?

In oceans, the saltwater pH is maintained by continuously growing algae, eating away wastes, and then broken down by colder temperature. It is challenging when it comes to the live aquarium with no natural degradation of wastes.

Testing water means keeping it clean, temperature checked, with maintained pH.

Final Thoughts

Your pet fish will love moderate temperature in a home aquarium. This species glow and grow better in the right environments and benefit the viewer with soothing sight to the eye. Although the fish tank does require a thorough cleaning after three days, the outcome is worth it.
