The Truth About Betta Fish: Top 5 Common Myths Debunked

Betta fish, also known as Siamese fighting fish, are very popular pets due to their vibrant colors, unique features, and low maintenance requirements. With the convenience of betta fish stores online and numerous king betta fish for sale, it has become easier than ever to add these beautiful creatures to your home. However, there are many myths and misconceptions surrounding betta fish that can lead to improper care or unrealistic expectations. 

In this article, we will debunk the top 5 common myths about betta fish and provide accurate information to ensure a happy, healthy life for your aquatic pet.

Myth #1: Betta Fish Can Live Happily in Small Bowls or Vases

One of the most common misconceptions about betta fish is that they can live happily in small bowls or vases. While it is true that betta fish can survive in these conditions, it is far from ideal. In the wild, betta fish inhabit shallow rice paddies and ponds with plenty of space to swim and explore.

A small container can lead to poor water quality, a lack of mental stimulation, and increased stress for your betta fish. It is recommended to provide a minimum tank size of 2.5 gallons, with 5 gallons or more being ideal. This will allow your betta fish to swim freely, reduce stress, and improve overall health.

Myth #2: Betta Fish Can Survive on Plant Roots Alone

This myth likely originated from the popular trend of placing betta fish in vases with live plants. While betta fish do enjoy resting on plant leaves and may nibble on roots, they cannot survive on plant matter alone. Betta fish are carnivorous and require a diet rich in protein. 

Feeding your betta fish a high-quality pellet or flake food formulated specifically for bettas, supplemented with frozen or live foods like brine shrimp, bloodworms, or daphnia, will ensure they receive the proper nutrition they need to thrive.

Myth #3: Female Betta Fish Can Live Together Peacefully

While it is true that female betta fish are less aggressive than their male counterparts, they can still display territorial behaviors and aggression towards each other. Some female bettas can coexist in a group, often referred to as a "sorority," but this requires a large, well-planted tank with hiding spots and plenty of space for each fish to establish its territory.

Introducing female betta fish to a sorority tank should be done carefully, and it is essential to monitor their behavior closely. If aggression continues or worsens, it may be necessary to separate the fish to prevent injury or stress. It is also worth noting that male bettas should never be housed together, as they are highly territorial and will likely fight to the death.

Myth #4: Betta Fish Do Not Need a Heater or Filter

Contrary to popular belief, betta fish do require a heater and filter in their tank. Betta fish are tropical creatures and thrive in water temperatures between 76-80°F (24-27°C). Maintaining a consistent temperature within this range is crucial for their health and well-being. A small, adjustable aquarium heater is ideal for achieving the correct temperature.

A filter is also essential for maintaining water quality and removing harmful toxins like ammonia and nitrite. Betta fish are sensitive to poor water quality, which can lead to stress, illness, and even death. A gentle sponge filter or other low-flow filter is perfect for betta fish, as they prefer calm water with minimal current.

Myth #5: Betta Fish Do Not Require Much Care or Attention

While betta fish may seem like low-maintenance pets compared to other animals, they still require attention and proper care to ensure a happy, healthy life. Regular water changes, water quality testing, and monitoring their behavior are all essential aspects of caring for betta fish. It is recommended to perform a 25% water change once a week and test the water parameters regularly.

Betta fish also enjoy mental stimulation, and providing them with toys, plants, and hiding spots can help keep them happy and entertained. It is also important to avoid overfeeding your betta fish, as this can lead to obesity and health problems. Feeding them small, frequent meals throughout the day is recommended, rather than one large meal.


Betta fish are fascinating creatures that can make great pets when given proper care and attention. By debunking these common myths, we hope to provide accurate information to help betta fish owners create a healthy and happy environment for their pets. Remember to provide a spacious tank, a balanced diet, a heater and filter, and regular care and attention to ensure your betta fish live a long and happy life.
