The betta fish is a gorgeous and interesting addition to an
aquarium. Also known as the “Siamese fighting fish,” the betta has
a very unique and feisty personality, making it a favorite among
amateur and expert fishkeepers alike.
If you haven’t owned a betta before, though, you may be a bit
intimidated about caring for one. Don’t worry: this betta fish care

Overview
Betta fish (B. splendens) are well-known for their combative
personality, as well as for their beautiful, long, flowing fins.
Bettas can still be found in their native rice paddies in Thailand
and Cambodia, but studies have shown that bettas are one of a
small number of animal species that actually live longer in
captivity than they do in the wild. The rice paddies where they
make their homes in the wild are susceptible to pollution, to the
extent that some varieties of bettas are now considered to be
endangered species.
Luckily, keeping a betta fish as a pet is easy, fun, and good for

both you and the betta. You can save the betta from bad water
conditions — not just in the wild, but also in some pet stores (more
on that later) — and you can gain a long-term friend. Betta fish are
some of the only fish that can form a genuine bond with their
owner, making them even more appealing for a potential
fishkeeper.
Before you run right out and buy a betta buddy, though, there are
some important things you need to know about how to take care of
a betta fish. Keeping the following things in mind will ensure that
your betta lives his or her best life, and you both have a great
experience.
Betta Fish Requirements
With all his attitude and flashing fins, the betta seems like a pretty
tough guy. It is important to note, though, that this type of fish can
be more susceptible to diseases, problems with water
quality/temperature, and dietary issues than some other fish.
It is even more important to note that the conditions that bettas are
kept in at the pet store are not optimal, so the first thing you have
to do is build a much better setup for your little guy or gal at home.
The essential requirements for keeping a betta fish are tank size,
water conditions, and diet. Here is a quick look at the minimum
requirements for each of these, so you can have everything set up
and ready before you bring your betta home.
Tank
Betta fish are so pretty that some people think of them more as a
decoration than a living, breathing creature. This is why they are
11/15/23, 12:00

often kept in small, decorative vases or cups in pet stores,
intended to show off their bright colors and long, flowing fins.
Unfortunately, these conditions are far from ideal. The smaller the
tank, the dirtier and less healthy the water is inside, and the plastic
cups are a pollutant in and of themselves.
So, with that being said, what is an ideal tank setup for a betta
fish?
While the recommendation for minimum betta tank size was once
2.5 gallons (9 liters), now expert fishkeepers recommend nothing
less than a 5 gallon (20 liters) tank.
No bowls!
Bowls are too small for betta fish, and they will be neither healthy
nor happy inside one.
The more space the betta has, the happier and healthier he or she
will be. Most betta fish owners (myself included) have seen the
most success with tanks that are at least 10 gallons (38 liters),
especially if they are keeping other fish as well.
Once you have a large enough tank, you can add plants and
gravel. Both natural and silk plants (not plastic!) are fine for betta
fish and provide great hiding places and mental stimulation — just
make sure to do your research on which natural plants the betta is
compatible with.
You should also make sure any artificial plants are clean and safe
to use. Check for sharp edges or points on the plants, because
you don’t want the betta to scratch himself when he swims past.
When it comes to gravel and substrate, your options are endless
(colorful, natural, glow-in-the-dark, etc.), but be sure to get a
11/15/23, 12:00

substrate that is made of smooth pieces. Bettas spend a lot of time
exploring at the bottom of the tank and can easily damage their
fins on rough rocks.
Water
Betta fish are from a tropical climate, so in order for them to stay
happy, you are going to have to make sure they have warm water.
The ideal temperature for betta fish water is between 76 and 80
degrees Fahrenheit (22 – 24 degrees Celsius). So, unless you live
in a tropical climate yourself, you will probably need to invest in a
tank heater to keep the water at the right temperature.
Aside from temperature, another important requirement for betta
fish is water conditioning. Tap water can be used in a betta tank if
you use a special water conditioner to make it safe for them (you
can usually find this in the fish care aisle at your local pet store).
Do NOT use distilled water, though, as this is missing several
minerals that they need.
When it comes to filters, there are multiple schools of thought.
Some say that as long as you keep the tank clean, a filter is not
necessary because bettas come from still waters. Others say that
a filter is needed to make sure the water conditions remain
optimal.
If you do choose to buy a filter, though, be sure that it is a gentle
one; otherwise, your betta will have difficulty swimming or may
even get pulled into it!
Diet
Betta fish are naturally carnivorous, meaning that they eat meat.

In the wild, they typically feast on insects and insect larvae in the
water. At home, you probably can’t recreate that experience for
them on a daily basis, but you can get pretty close.
Betta fish can eat specially made pellets and flakes that contain
dried insects, shrimp, and other things they would naturally eat.
Just watch out for brands that contain wheat and/or corn, as bettas
have trouble digesting this and it could lead to illness.
Bettas can also eat certain types of live, frozen, or freeze-dried
worms, shrimp, mosquito larvae, and even wingless fruit flies. The
important thing is that the betta gets lots of protein.
How to Care for a Betta Fish
Now that we know more about betta fish and what they require,
here is a step-by-step betta fish care guide to get you started.
Step 1: Prepare The Tank
Before you even consider bringing home a betta, you must first get
the tank ready. Buy a tank that is at least 5 gallons (though 10 is
better) and clean it — with just hot water, no soap!
Step 2: Set Up the Tank
Add your (clean) substrate, plants, heater, and filter (if you are
using one) to your tank to provide your betta with hiding places
and decorative touches. An expert tip is to fill the tank halfway,
then add the substrate and plants so that they stay in place when
you add the rest of the water.
Step 3: Check the Conditions
11/15/23, 12:00

Theoretically, once you have the water at the right temperature,
the filter set up, and the decorations in place, the tank is ready to
introduce the betta. But if you really want to do it right, it is
recommended to cycle the tank. This is a process in which you let
the healthy bacteria inside the tank grow for a while so that the
conditions are optimal for the betta.
Whether you cycle the tank or not, never add the betta without
checking the nitrate, nitrite, ammonia, and pH levels first. You can
find kits to test these things at the pet store or online.
Step 4: Choose a Betta
Most people probably think this should be step one, but not if you
want your betta to thrive in his or her tank!
Once the tank is ready, head to the pet store. Look for bettas that
appear healthy: bright colors, bright eyes, fins that are not torn,
discolored, or covered in a filmy substance, no strange bumps on
the body. You should also look for bettas in clean water and who
seem alert and interested, not just sadly sitting on the bottom of
the tank.
You get bonus points if the betta has bubbles on the top of its
water: this means it is already happy.
Step 5: Introduce the Betta to the Tank
Once you have chosen your betta buddy, you will probably be
itching to add it to the tank. Not so fast!
Introducing a betta to a new tank too soon can lead to shock and
even death. First, you must allow the water in container the betta
came in to reach the same temperature as the water in the tank.
11/15/23, 12:00

To do this, clip the container to the inside of the tank so that it
floats in the tank water (but don’t submerge it, bettas need
oxygen!).
After about 15 minutes, the water should be coming closer to the
same temperature, but the other conditions are not the same. To
remedy this, gently pour some of the tank water into the betta’s
container so it can adjust to it. Repeat this process at least one
more time, until the water is exactly the same temperature. Then,
finally, you can gently release your betta into his new home.
Step 6: Feed Your Betta
Aside from a proper tank, the most important aspect of betta fish
care is feeding. It is recommended that you feed your betta twice a
day, once in the morning and once at night. Just two to three small
pellets should suffice — bettas have small stomachs, so giving
them too much food can cause digestive problems.
A few treats in the form of freeze-dried bloodworms or similar fare
can also be given once or twice a week.
Step 7: Keep the Tank Clean
To keep your betta healthy and feeling great, you have to clean
the tank regularly. How often you do this depends on the size of
the tank and whether or not you are using a filter. If your tank is
small-ish and has no filter, you should change 30-50 percent of the
water once a week. If it is larger, you can get away with cleaning it
every 10-14 days.
Be careful when you do this, though, and remember to treat the
water with water conditioner, as you don’t want to add in cold or

untreated water and send your poor betta into shock!
Frequently Asked Questions about Betta Fish
How long do betta fish live?
On average, betta fish live from two to four years, with the females
outliving the males by a few months. There have been cases,
though, where a betta has lived to be a teenager!
How much do betta fish cost?
There are a lot of factors to consider when it comes to pricing a
betta fish. Things like coloring, species, and age all come into play,
but the price range of a betta fish alone (without adding in the tank,
substrate, filter, etc.) can range from around $2 to around $80.
Do betta fish need a light?
Betta fish need a daily light/dark cycle to keep all of their bodily
functions running smoothly. If your betta is kept in a room that
regularly sees light during the day and darkness at night, you don’t
really need an artificial light.
But if you keep your betta in a dark basement or an unused room
without much in the way of lighting, installing an artificial light and
using it during the day could be very useful. Just be sure to turn it
off at night — too much light is just as bad as not having enough.
Do betta fish get lonely?
Loneliness is one thing you never have to worry about with betta
fish. Betta fish are solitary, and typically prefer to live alone.

While some females do enjoy living with a couple of other female
bettas, the males (and even some females) are aggressive and
are best kept on their own. If one male betta is put into a tank with
another male betta, they will constantly be fighting for territory,
which can result in damaged fins or even death for one or both of
them.
Can bettas live with other types of fish?
Yes and no. Some bettas can live with other species of small,
calm, bottom-dwelling fish such as Kuhli loaches, catfish, some
varieties of tetras, and snails, but it really depends on the
personality of the betta. If the betta is very territorial, it is best to
keep him or her in her own tank.

More!)
How often should I feed my betta fish?
Twice per day is ideal, but take care not to overfeed. This can lead
to cloudy, dirty water, as well as gastrointestinal issues. The
stomach of a betta is only as big as one of its eyeballs, so it is
easy to see how quickly they could get filled up!
Can you breed betta fish at home?
Yes, but it is not for fishkeepers who are looking for a quick and
easy way to make money or something of that nature. It takes a lot
of time — and a lot of tanks — to breed betta fish, as well as a lot
of consideration and preparation.
First, you must choose the right mating pair, then set up a tank for
11/15/23, 12:00

each of the two bettas and let them acclimate for at least a month.
Then, you will need a tank specifically dedicated to breeding,
where the eggs will be laid, and the babies (called fry) will
eventually hatch and grow.
You have to keep these fry separate from the male betta when
they start to grow. Otherwise, they will be eaten, so you have to
keep an eye on your fish if you don’t want to lose any of them!
Additional Tips and Tricks
Be sure that your betta fish tank has a lid
Bettas are notorious for being jumpers — some even jump right
out of the tank! While their unique breathing system makes it
possible for them to breathe air for a time (some have been known
to survive out of the water for a whole day), this is definitely not a
situation you want to put them in.
Don’t let your betta get bored
Small tanks with no decorations or hiding places can cause bettas
(males in particular) to get listless and start biting their own fins.
This leads to rips and tears and eventually to infection and illness,
so always be sure that your betta has plenty of things to look at
and interact with in his tank.
Don’t tap on the glass
While sticking your finger up to the side of the tank to encourage
your betta to flare and interact with you is fine (and is even
encouraged to judge his health and alertness), don’t tap on the
glass. This is very disturbing and scary to the fish. How would you
11/15/23, 12:00

like it if someone started banging and shaking your house just to
see how you would react?
Use a mirror to play
Another way to keep a betta in shape and to check his stamina is
to hold a mirror up to the tank. Bettas love a good fake fight, and
would really enjoy flaring at this other fish that looks just like them.
Just don’t leave the mirror up for long periods of time, or he will get
overtired.
Establish a routine
Bettas can come to recognize and even show affection toward
their owners. The most important step towards forming this kind of
bond is to create a routine and stick to it. Feed your betta around
the same time every day and frequently spend time interacting
with him so that he gets used to you and comes to expect that you
will be there.
When he sees you, he will be happy, and so will you!
Conclusion
Betta fish can bring a lot of color, fun, and joy into your home. But
if you want your betta to thrive, you have to provide it with proper
tank and water conditions, a healthy diet, and enough mental
stimulation to keep it feeling alive and alert. If you can do all of
these things, you will be sure to have many happy years with your
beautiful betta buddy.
