Platinum Halfmoon Betta (Betta splendens)

The Platinum Halfmoon Betta (Betta splendens) is a highly sought-after freshwater fish known for its striking metallic snow-white coloration and a dramatic tail fin that spreads into a perfect 180-degree half-circle. Because of their heavy, delicate fins and unique genetics, they require precise aquarium care to stay healthy and vibrant.

Core Requirements & Water Parameters

Minimum Tank Size: 5 gallons (19 liters) minimum, though a 9-gallon (35 liters) tank is preferred.

Water Temperature: Strictly tropical, maintaining 24°C to 28°C (75°F to 82°F).

pH Range: Slightly acidic to neutral, ideally 6.0 to 7.0.

Diet: Carnivorous; feed them high-quality betta pellets, frozen bloodworms, and brine shrimp.

Special Habitat Considerations

Gentle Filtration: Heavy halfmoon fins make these fish slow swimmers. Use a sponge filter or a filter with an adjustable, low-flow intake so they do not get trapped by the suction.

Safe Decor: Avoid plastic plants or sharp rocks that can shred their delicate tail. Stick to live plants (like Anubias or Java Fern) and smooth silk decorations.

Tankmates: Males must be housed alone. They are highly territorial and will fight other bettas or mistake colorful, long-finned fish for rivals.
