Betta Fish
The betta fish, or Siamese fighting fish (Betta splendens), is a vibrant, freshwater species native to Southeast Asia.
Known for its striking colors and flowing fins, this small fish, typically 2-3 inches long, thrives in warm, slow-moving waters.
Bettas are popular due to their beauty and relatively easy care, though males are territorial and best housed alone. With a lifespan of 2-4 years, they’re a captivating addition to our range of aquatic species.

These are designed for the female to deposit her eggs into and the male then takes care of them.
Conservation Status
The betta fish (Betta splendens), commonly known as the Siamese fighting fish, is classified as Vulnerable in its native range, primarily in Thailand, Laos, Cambodia, and Vietnam, due to habitat loss from agricultural expansion, pollution, and urbanization. However, the global population is not at immediate risk of extinction because of its widespread presence in the aquarium trade and captive breeding programs.
