Betta fish regularly attract aquarium hobbyists. Most of them think they can do well by buying a tiny cube as an aquarium and a plastic plant as decoration. But that is not true at all.

There are lots of myths regarding this. In fact, the wrong advice given by sellers or misinformed people is sometimes fatal. The betta fish may be very resistant; they suffer from these poor living conditions and can die very quickly in a few days, or slowly after one year. And this is far from their healthy life expectancy!

So, what to do?

If you are here to know how to keep a betta fish happy, you are at the right spot. You will discover absolutely everything that is needed to make Betta happy and keep him healthy.

How to Keep a Betta Fish Happy

The rule of thumb of keeping betta happy is to take care of his food, and accommodation. Furthermore, you should pay heed to some other things. Let’s see what they are-

1. Keep It Healthy

How do you know if your Betta is doing well if you do not recognize sick Betta? The distinction is paramount.

Healthy Betta

  • Swims when you approach
  • Has bright colors
  • Fins in good condition
  • Parade when facing another male: it spreads its lids (cheeks) and fins

Sick Betta

  • Is lethargic and often hidden
  • Has a dull color
  • Damaged fins
  • May have white spots and lumps
  • Breathe hard

Filter out the sick bettas as soon as possible and ensure the proper treatment. Otherwise, they will affect healthy bettas as well.

2. Food

Feeding can make anyone happy. The same goes for our betta fish. Betta fish are carnivorous. That is why they need specific food and supplement.

In nature, bettas feed on insects and larvae on the surface of the water. It is necessary to reproduce this diet so that they are in good health and happiness.

The persistent refusal of any food may mean they really don’t want the food. And also maybe it’s time to change the brand. Or you can mix two different brands.

Bettas are particularly fond of live food, such as worms and artemias. You can check this guide on how to feed your Betta fish from here.

3. Avoid over-feeding!

It is difficult to estimate how much food you should give to the Betta. Food labels are often imprecise and inconsistent. Their stomachs are about the size of their eyes, and the granules may expand after ingestion.

Often overeating leads to bloating, constipation, swim bladder problems, and an accumulation of waste in the aquarium. So, give your betta fish only that amount of food it can eat in a short time. For example, provide that amount it can eat in 2 minutes. If you want a happy and healthy betta fish, you should not overfeed it at all.

4. Adequate size of the aquarium and environment

The absolute minimum size of the aquarium to have healthy Betta is 10 liters, the recommended size being 20 liters or more. Another advantage is that larger aquariums are more stable and require less frequent cleaning.

We often hear that the bettas need the least space and they can be satisfied with a ball or a cube of 2 liters. It’s wrong. To ensure a reasonable life expectancy, there are lots more to do.

For example, put yourself in the situation. We could all survive by spending our time in a small room if we are given food every day, but we would not be happy or healthy.

So, you should not fill your aquarium at maximum volume. The bettas need to access the surface of the water to breathe.

5. Adequate natural and artificial light

During the day, the betta fish need light to move and play. But at night, they need a dark environment to be able to sleep. This rhythm reproduces the natural day/night cycle makes it possible to regulate their internal biological clock.

The fish do not like to end up directly under intense lighting. This is particularly true for the Betta. You should put such plants and other decorations which can provide shade. If they no longer want to be exposed to light, it will help them to hide.

Avoid direct sunlight as it can quickly raise the temperature of the water and cause undesirable algae to grow along with the glazing. Artificial lighting is recommended, placing the aquarium away from the windows. In this way, you can control the intensity and duration of the light.

6. Aquarium Companions

Bettas are known to be aggressive. With other species, they are relatively calm. They can even be jostled by the most vivid and vigorous. But when they are with the same species, they are always aggressive.

Never put male Betta in the same aquarium as another betta, be it male or female. The males will fight and punch each other until one of them dies or is seriously injured.

Likewise, if a male is with a female outside the breeding season, he will chase her until she dies of exhaustion. Fish of other species can only accompany male Betta. Choosing compatible tank mates can make your betta happy.

7. Plants, hiding places, decorations

Pants and hiding areas allow Betta fish to feel safe and happy. Mimicking their natural habitat helps reduce their stress. They love the places where they can hide, and they feel safe there. So have fun with the decor of the aquarium to provide many hiding places!

However, be careful with artificial plants and decorations. They can damage your Betta’s precious fins. Focus on fake fabric plants, not stiff plants, as they will be less likely to hurt your Betta.

8. Temperature

Bettas need hot water. Keep the temperature between 24 and 27 degrees. This is the temperature at which the bettas are the happiest and most active. Never go below 24 degrees, and above 28 degrees.

9. Water quality

What water to use for Betta? Tap water, reverse osmosis water, or mineral water? The choice may not be as obvious as you thought! You can get a water conditioner for your betta fish.

The water should be free of chlorine and other contaminants for the safety of your Betta fish. If using tap water, use a water conditioner to remove chlorine and other heavy metals. Do not use only distilled water or reverse osmosis water, as both plants and fish need minerals in the water.

10. Maintenance of the aquarium

Keeping the aquarium clean is crucial for Betta’s health and happiness. As your Betta gets rid of the food it digests, it ends up in the water of the aquarium. The smaller the aquarium, the faster it gets polluted. It is also for this reason that it is recommended to choose an aquarium of 10 liters minimum, ideally 20 liters. The parameters are more stable, and the maintenance is lighter.

If your aquarium is not filtered, it is necessary to make three water changes per week, 20% each. A filtered aquarium will only need a weekly water change of 20%. It is not necessary to take your Betta from the aquarium for the frequent water changes.

If you follow these 10 tips, you should be able to keep your betta fish happy and healthy.
