Betta Fish Care 101: Maintaining Optimal Temp [2023]

by
Betta Fish Care 101

Betta fish comes from Southeast Asian countries, where they’re adapted to living in warm water.

They happily thrive in a fish tank where the water temperature ranges between 76 and 82 degrees Fahrenheit.

And then suddenly keeping them in cold water may affect them badly!

Well, a sudden shift in water temperature may affect your betta in an Awful way.

Let me tell you how –

They start becoming sluggish and inactive.
They become more susceptible to illness and infections.
They start losing their colors.
Their metabolism slows down to a level where they cannot absorb the required nutrients.
They become stressful.

And as a fish parent, no one wishes to see that!

So, if you like to keep the water temperature in check, here are 15 practical ways to control it:

How to Control Betta Fish Tank Temperature?

Finding a Cool Shaded Place in Your House

The first step to controlling the temperature of your betta fish tank is ensuring that you use an accurate thermometer.

If you don’t, you could give your betta fish tank a reading that’s way off-base.

So here are some tips for checking the accuracy of your thermometer:

Use an Accurate Thermometer

It might seem obvious, but it’s essential to have a reliable and functioning thermometer to check the temperature regularly.

To check whether or not yours has been damaged from previous use, you can drop it into cold water and see if the temperature reading changes significantly from what it was before.

The new reading should be about 0 degrees Fahrenheit higher than before.

You should also ensure that there aren’t any cracks in the glass and that all parts are firmly attached.

Don’t leave old ones lying around where they can be broken accidentally by pets or children; replace them every few years to be safe!

Finding a Cool Shaded Place in Your House

Finding a cool shaded place in your house is child’s play.

Cool places are usually found in the basement or on the top floor of the house.

Do not put the tank near windows, air conditioning units, or heaters, as these things may be too hot for your betta fish.

Also, keep the tank from direct sunlight because this will heat your tank’s water very quickly and could potentially kill your betta fish!

Using an Aquarium Chiller

An aquarium chiller is an excellent option to cool down your betta tank.

This device is specifically designed to reduce a tank’s temperature.

And although it works like a charm, the biggest downside is its Pricing.

It’s expensive and noisy.

Some are also hard to install and may require professional installation if you’re not experienced with electrical work.

If you decide on an aquarium chiller, buy one that’s already compatible with your betta fish tank setup.

So this way, it doesn’t waste energy cooling water from another source.

Using an Aquarium Heater

Aquarium heaters are an excellent option for controlling your fish tank temperature.

Here’s how to install and maintain an aquarium heater:

First, plug in the heater and wait for it to warm up before attaching it to your fish tank.
Make sure you don’t place the heater where your betta can reach it—it should be at least 1 inch away from his reach if he jumps out of the water.
Once you’re sure it’s safe, carefully attach the suction cups on either side of the glass tube, so they’re firmly attached without creating any gaps between them.
Then gently place this “stick” inside your aquarium.
If it doesn’t fit snugly between two surfaces behind another object (like a rock), move something around until both ends are even with one another but not blocked by anything else!

This will make sure that your pet fish stays secure in the tank.

Selecting the Right Betta Fish Tank Size

When choosing a tank, you must consider the number of fish you want to keep.

And according to that, select the right size for your betta fish tank.

If you only have one or two betta fish, a small tank will be enough for them.

You can even use an aquarium with an opening on top and make it like a bowl with gravel inside.

However, if you want to keep a school of betta fish, getting a bigger tank would be a smarter choice as it will allow more space for each fish and give them room inside the tank.

Drip System Installation

Drip system installation is one of the most effective ways to keep the temperature of your aquarium at a constant level.

This is because drip systems are easily adjustable.

Because of its adjustability, you can ensure that your betta fish always has the right amount of water on them.

If you’re thinking about getting a drip system installed in your tank, here’s everything you need to know:

While it might look complicated in theory, installing a drip system is pretty straightforward.
As a matter of fact, anyone can do it without too much difficulty (even if you’re not particularly handy).
All you have to do is connect some tubing from your tank’s pump through an opening near its bottom, then secure another tube at the top for drainage purposes!
Once installed, Drip systems are effective at maintaining temperatures.
Compared with other methods like heaters or heat lamps, a well-placed trickle system can keep temperatures stable at around 70 degrees Fahrenheit year-round.
And that too, without any further maintenance on your part after the initial setup has been finished correctly.”

Put the Lid on the Top of the Tank

Make sure that the lid is on top of the tank.

Putting a lid on your fish tank will help retain heat and keep out light.

As you may already know, too much light can also lower its temperature, so you’ll need to adjust your lighting accordingly.

A better option for a betta fish would be a tank with plastic or glass lids!

Cleaning the Aquarium Regularly to Prevent Algae Growth

To prevent algae from growing in your aquarium, clean it regularly.

That’s one thing you gotta do.

  • You can remove the algae with a toothbrush or gravel vacuum or use an aquarium scraper to remove dead fish and plants.
  • Remove uneaten food and wash out filters regularly as well.
  • If you have a betta fish tank prone to algae growth, consider using aquarium salt too!

Constantly Monitoring Water After Replenishing it in the Tank

Have you ever been in a situation where you cannot control water temperature despite all the necessary checks?

If that’s the case, I’ve got a solution for you – You must constantly monitor it at least once a day.

Monitoring becomes even more critical if your betta fish becomes stressed or lethargic (or if he starts acting strangely).

Once you figure out why they’re acting strangely, you must remove some warmer or cooler water from the tank and add new to meet the ideal range.

Avoid Overcrowding Your Betta Tank

Overcrowding is the biggest culprit behind your betta dying in the fish tank.

It leads to stress, aggression, and fighting between your fish.

When bettas don’t have enough space to swim around and room to breathe, their chances of getting sick increase by a mile.

Overcrowding is a problem because too many fish in one tank will use up all the oxygen in their water quickly, and then there will be none left for them or any other living creature inside the tank!

If there isn’t enough oxygen in their water, this causes stress, making them more susceptible to illness or disease from bacteria like fungus growing on their bodies.

This leads back to why you need space for your little betta fish when keeping them home in your fish tank!

Avoiding Materials That Absorb Heat (Glass Bowl)

Newbie fishkeepers tend to make a silly mistake by keeping their betta fish in a glass bowl.

Let me tell you how –

Glass bowls are very prone to heat absorption.

Therefore, making them an unsuitable option for home aquariums.

As a material with high thermal conductivity, it’s easy for glass bowls to absorb heat from the room.

And then transfer it directly into your fish tank.

This leads to a sharp temperature spike in your betta fish tank.

So, the best thing for you would be to Avoid using materials that absorb heat.

Or be ready to face deadly consequences.

When cleaning the betta fish tank, you may need a temporary bowl. So, it would be best to use an opaque white or opaque black bowl instead of a glass bowl.

Keeping Your House Cool With Air Conditioner

Just when the summer season comes around, it’s pretty common to feel the heat!

Yeah! Feeling that?

Whether winter or summer, maintaining a stable temperature can be an uphill battle.

In the winter, you can set up Aquarium heaters.

But what about the scorching heat in the summer?

There are several ways to keep your house cool.

If you have an air conditioner, ensure it’s running at noon and night.

You can also use a fan to circulate the air around the room.

Well, for that, you should place your fish tank where it can utilize the cooling of running air conditioners.

If you’re comfortable with it, put some fans in your tank too!

The blowing air will help keep things moving around, so there’s less stagnancy or heat buildup.

To be safe, do not place an aquarium near windows or doors that receive direct sunlight for extended periods (during summer).

Learning Betta Fish Temperature Tolerance Limits and Preferred Range

Before keeping betta fish in your tank, you must know everything about them.

Let’s learn about these fascinating creatures’ life cycles and behavior:

Betta fish are tropical fish that require warm temperatures to thrive.
They have been bred for centuries in Thailand, Vietnam, and Cambodia to be aggressive toward one another during competitions.
Betta fish is also known as Siamese fighting fish. Here, the name “fighting” comes from bettas biting each other if kept together in captivity for too long.
However, not all bettas will fight with each other!
Some females can become territorial when breeding or protecting their fry (baby fish).
But it is possible to keep them together peacefully if they’re not sparring partners or siblings.
You can tell whether or not your pet has been bred for aggression by looking at its fins!
Most showy male varieties have long-flowing fins, while less aggressive females have short-rounded ones.

Using Water Filters Carefully and Keep Them Clean Always

Water filters are an effective way to control the temperature of your betta fish tank.

The type of water filter you use depends on the size and shape of your tank, as well as how many fish you want to keep in there.

You can use one or more types of filtration at once.

Mechanical Filtration

This type of filter physically removes debris from the water.

Keeping these clean is critical because they may become clogged with dirt and other particles that can harm your fish.

If they get clogged, it will take away some of their efficiency in cleaning up after themselves.

And also, it would be best if you were careful not to over-clean them or change out too much water all at once.

Otherwise, this could cause nitrate poisoning, and it may take forever for your betta fish to recover.

Mechanical filters have a lower rate at which they remove chemicals from water.

But the good thing is, they’re still effective when used correctly!

Chemical Filtration

Chemical filters remove chemicals from aquariums by chemically bonding them together so that they won’t affect living things anymore.

This process is called denitrification (or nitrification).

There are two types: biological media, like bacteria colonies growing on carbon, absorb ammonia/ammonium and cause toxicity issues for fish; chemical media, such as activated charcoal, absorbs discoloration.

Placing Live Plants in Aquarium

Keeping these live plants in aquariums is a great way to help control betta fish tank temperature.

Plants can provide several benefits, including cleaning the water and providing oxygen for your Betta fish, reducing ammonia levels, and even controlling stress levels in your fish.

Plants absorb carbon dioxide and release oxygen into the water, which helps keep Betta Fish healthy.

If you have live plants in your aquarium, they will use up some of that dissolved CO2 while they’re respiring (breathing).

So less will be released into your tank’s atmosphere every time you open it up to check on things!

Now you know the importance of live plants, the biggest challenge revolves around their maintenance.
