Super Red Halfmoon Betta (Betta splendens)

The Super Red Halfmoon Betta (Betta splendens) is one of the most popular and visually striking freshwater aquarium fish, celebrated for its solid, intense crimson coloration and a majestic caudal fin that spreads at a full 180-degree angle resembling a half-moon

Quick Care & Profile Summary

Minimum Tank Size: 20 to 30 liters (5 to 10 gallons). Never keep them in tiny bowls.

Water Temperature: Ideal tropical climate at 24°C to 28°C (requires an aquarium heater).

pH Range: Slightly acidic to neutral (6.4 – 7.0).

Diet: Omnivore/Carnivore. High-quality pellets, frozen bloodworms, and brine shrimp. Feed foods rich in carotenoids to enhance their deep red color.

Key Characteristics & Maintenance

Delicate Fins: Because of their expansive, heavy finnage, they are prone to fin tearing. Avoid sharp plastic plants or rough decorations; opt for live or silk plants instead.

Low Flow Filtration: Large fins make swimming against strong currents exhausting. Use a sponge filter or a filter with an adjustable, gentle flow.

Color Enhancement: To make their solid red hue stand out, use a dark substrate (like black gravel) and a dark aquarium background.

Temperament: Highly aggressive toward other males. They must be kept singly in a tank, though they can sometimes live with peaceful, short-finned bottom dwellers like Corydoras catfish.
