Betta Fish: What Are They And How Do They Live?

Bettas are popular aquarium fish that are often kept by hobbyists because of their colorful appearance and unique behavior patterns. These fish are native to Southeast Asia and were originally bred for ornamental purposes. Today, however, many people keep them as pets due to their peaceful nature.

The most common type of betta is the goldfish-sized betta which has been selectively bred for its bright colors. Other types include the dwarf betta, which is smaller than the goldfish variety, and the tiger betta, which is larger than the goldfish. Bettas come in a wide range of colors including red, orange, yellow, green, blue, purple, black, white, and even pink.

Aquarium owners usually buy bettas from pet stores or online retailers. However, some breeders sell directly to customers who wish to raise their own bettas. Bettas require a lot of space in order to thrive, so it’s recommended that you purchase a tank that holds at least 10 gallons of water. Bettas like to swim freely and enjoy hiding under rocks and plants. Some species may prefer to live in groups, while others prefer solitude. Bettas are omnivores and eat algae, insects, and small crustaceans.

Bettas are generally friendly toward humans and will allow you to handle them without fear. They’re also quite docile and will rarely bite unless provoked. Bettas are known to be territorial and will defend themselves against other fish. It’s important to remember that bettas do not tolerate being touched underwater.

Bettas can live up to 5 years in captivity, but most die within 2 years. Bettas are prone to diseases such as amoebic gill disease, bacterial infections, and fin rot. To prevent these problems, make sure to clean your betta’s tank regularly and change the water every two weeks.

Here are some tips to help you care for them properly:

Water Quality

Bettas are freshwater fish, which means they require clean, fresh water. However, many people who keep bettas think that their tanks are perfectly fine because they live in a city or town. Unfortunately, this is not true.

The problem with living in a city is that the water quality is often poor. Many cities add chemicals to their water supply to kill bacteria and algae, but these chemicals can damage bettas. In fact, some of these chemicals can even cause death.

If you live in a city, you should invest in a filter system that removes chlorine from your tap water. Chlorine kills bettas by damaging their gills. If you don’t have a filter, then you should try to buy bottled water. Bottled water has no additives, so it won’t harm your bettas.

However, if you live in a rural area, you may not have access to bottled water. Instead, you should purchase a filter system that uses reverse osmosis technology. These filters remove impurities from the water before it enters your tank.

Another thing to remember about water quality is that it varies throughout the year. During the summer months, you should use filtered water. However, during the winter months, you should use unfiltered water.

During the winter months, there is less sunlight hitting the surface of the water, which causes fewer nutrients to enter the water. As a result, you should feed your bettas twice per week during this time.


Bettas like bright lighting. However, too much light can actually hurt your bettas. For example, if you place your betta in direct sunlight, he will burn his eyes.

Instead, you should place your betta in a dimly lit aquarium. This way, he will receive adequate amounts of natural light without being exposed to harmful levels of UV rays.

You should also make sure that your betta doesn’t spend too much time under fluorescent lights. Fluorescent lights emit blue light, which can disrupt your betta’s circadian rhythm. As a result, he will become lethargic and depressed.


Bettas need warm temperatures to thrive. However, they do best when the temperature fluctuates between 70°F and 80°F. In addition, you should avoid placing your betta in cold water. Coldwater can shock him, causing stress and injury.


Provide your betta with a good diet consisting of flake food, frozen foods, and live foods. Bettas eat small insects such as mosquito larvae, crickets, and worms. You should feed them these foods every day. You should also feed your bettas frozen bloodworms. Bloodworms are easy to obtain and are inexpensive.


Bettas love swimming. Therefore, you should give your bettas plenty of opportunities to swim. You should also allow your bettas to exercise themselves by jumping out of the water. Jumping stimulates your bettas’ muscles, making them stronger. Keep your betta in a large tank with plenty of room to move around. Avoid overcrowding your betta’s tank.


Clean your betta’s tank thoroughly every week. Cleanliness is important for all animals, including bettas. Therefore, you should regularly clean your bettas‘ tank. Scrubbing the gravel with a brush and cleaning the glass with a sponge are two ways to clean your bettas’ tank. Change the water in your betta’s tank every two weeks.

Health Care

Your bettas should be checked by a veterinarian at least once per month. This is especially true if your bettas are older than 6 months old. If your betta becomes ill, consult a veterinarian immediately.
