Our Top 5 Betta Fish Facts

1. The Siamese fighting fish is not the only betta

While the best-known species of betta is the Siamese fighting fish, this is by no means the only variety! There are around 65 individual types of betta fish, although the Siamese fighting fish or “Betta Splendens” is by far the most commonly domestic-kept betta.

2. The betta originates from Thailand

As the “Siamese” part of the name suggests, the Siamese fighting fish and other bettas originate from Thailand, previously called Siam. In their natural environment, bettas live in the shallow, marshy fields of rice paddies. For this reason, they thrive in a shallow tank with a large surface area.

3. Siamese fighting fish were originally fought deliberately

When people in Thailand realized that two male bettas together would put on impressive threat displays and fight each other, they would often actively select and keep fish with significant fighting prowess, and use them to fight other fish in competitions. This “hobby” died out towards the end of the 1800s.

4. Bettas are carnivorous

While most domestic fish are omnivorous or vegetarian, meaning that they either eat a mixture of plant and animal matter or plant matter only, the betta is an obligate carnivore, meaning that the main or entire part of their diet must consist of animal matter in order for them to thrive.

In captivity, the betta prefers to be fed food such as brine shrimp and blood worms, but they will also eat specially prepared pellets and flake food designed to meet their needs. You can even buy pre-prepared food mixes specific to bettas, which provide for all of their needs and help to enhance their bright, vibrant colors.

5. Bettas can breathe oxygen

Unlike the vast majority of small fish, the betta species has an organ within their heads known as the labyrinth organ, which allows them to breathe oxygen from the air rather than solely from the water.

This evolutionary advantage helped the betta to survive in conditions that are hostile to most other fish, such as very shallow rice paddies and slow moving streams. However, your betta does of course need to live within the water, and should never be removed from the tank!
