Half Moon Betta - Metallic Marble
A Halfmoon Metallic Marble Betta (Betta splendens) is a highly prized, dynamic aquarium fish known for its D-shaped tail and color-shifting scales.
Key Characteristics
Halfmoon Tail: The caudal (tail) fin spreads at a full 180-degree angle when flared, creating a perfect capital "D" shape.
Metallic Trait: The scales have a thick, shiny, iridescent layer that reflects light, giving them a polished or armored copper, teal, or silver appearance.
Marble Gene: This genetic trait means the fish will change colors over time. A patch of dark color can completely disappear, or new colors can spread across the body as the fish ages.
Tank Requirements
Size: Minimum 5 gallons (19 liters).
Filter: Low-flow sponge filter (heavy fins make swimming in strong currents difficult).
Temperature: 75°F to 80°F (24°C to 27°C) using a reliable aquarium heater.
