1. Betta Fish (Siamese Fighting Fish)
Betta fish are among the most popular aquarium fish due to their striking colors and flowing fins. They come in dazzling shades of blue, red, purple, yellow, and even iridescent hues.

Unique Qualities of Betta Fish
Betta fish, also known as Siamese Fighting Fish, are admired for their vibrant colors, flowing fins, and unique personalities. One of their most striking qualities is their ability to breathe air through a special organ called the labyrinth, allowing them to survive in low-oxygen water. Males are highly territorial and display dramatic flaring when threatened. Unlike many fish, Bettas can recognize their owners and even learn simple tricks. They thrive in small, well-maintained tanks and prefer warm water. Their ability to live alone without needing a school makes them an ideal choice for beginner fish keepers.
