Betta fish, also called Siamese fighting fish, are one of the most popular aquarium fish in the world. They are appreciated for their bright coloration, long flowing fins, and for being very personable. Though they are frequently advertised as low-maintenance aquatic pets, betta fish require specific care in order to live a long and healthy life. There are so many common things I see beginners do that inadvertently cut a betta’s life short.
This guide covers all your questions about betta fish everything from their natural habits and setting up a tank to feeding, health, and common misconceptions.
What Is a Betta Fish?
The Betta fish is from freshwater habitats in Southeast Asia, primarily Thailand, Cambodia, and Vietnam. In the wild, their habitat is shallow bodies of water, such as rice paddies, ponds, and slow-running streams. These settings are warm, quiet, and usually low in oxygen.
Some other types of fish can’t do this because they lack the labyrinth organ. What is a betta?. The cool thing about a betta is that it has something called a “labyrinth organ,” which means it breathes air at the surface (unlike several other kinds of fish). This adaptation allows them to survive in oxygen-deprived waters, but it does not make them immune to dirty or overcrowded tanks. Of course, clean water and proper care are still important.
Types of Betta Fish
There are various types of betta fish, each known for their unique fin shape, color, or pattern.
Veiltail Betta
Veiltail bettas are the most popular and easiest to find. They have long, droopy fins that flow down. Hardy and versatile, this is a variety often recommended for beginners.

Halfmoon Betta
Halfmoon bettas have very large tail fins, and when they are flared, they will extend 180 degrees. They are beautiful but more fragile than other kinds. An ideal tank environment is also very critical to their fin health.
