Description

Key Characteristics
  • Fin Spread: The caudal (tail) fin spreads to a 180-degree or wider half-moon shape when flaring.

  • Size: Grows up to roughly 2.5 inches (6.5 cm) in length.

  • Colors: Appears in vibrant shades like red, blue, yellow, and multi-colored patterns.

  • Labyrinth Organ: Possesses a specialized organ that lets the fish breathe oxygen directly from the air at the water’s surface.

Care and Behavior

  • Solitary Living: Must be kept alone because male bettas are extremely territorial and will fight other males to the death.

  • Water Flow: Needs a gentle filter because heavy, flowing fins make swimming difficult in strong currents.

  • Diet: Feeds on high-quality betta pellets, bloodworms, brine shrimp, and daphnia.
