Yes, Siamese fighting fish (primarily *Betta splendens*) are classic tropical fish. Here’s a detailed breakdown of their characteristics:
Tropical Fish Traits
Native Habitat
- Originates from slow-moving waters like lakes and rice paddies in tropical Thailand, adapted to warm aquatic environments.
Temperature Requirements
- Ideal water temperature: 22–24°C (72–75°F).
- Minimum threshold: 18°C (64°F); prolonged exposure below 15°C (59°F) increases disease risk.
Physiological Features
- Possesses a labyrinth organ (folded gills), allowing it to gulp air and survive in low-oxygen waters— a common adaptation among tropical fish.
Hallmarks of Tropical Ornamental Fish
- Vivid coloration (metallic red, blue, green, etc.) that aligns with the high color saturation typical of tropical species.
- Ranked as "one of the most commercialized tropical fish," widely distributed in global aquarium markets.
Note: All species in the *Betta* subfamily inhabit tropical regions, but *Betta splendens* is the most intensively domesticated ornamental variety.
