Buying Guide
What size tank should I use for halfmoon bettas? A minimum of 5 gallons per betta is recommended, with gentle filtration and stable temperatures around 76-80°F. Avoid aggressive tank mates to protect the flowing fins.
How should I monitor water quality? Regular partial water changes (about 20-25% weekly) and a reliable aquarium test kit help maintain low ammonia and nitrite, with nitrate kept under control.
What lighting works best? Moderate lighting enhances color without stressing the fish. Avoid intense direct sunlight, which can cause algae blooms and temperature swings.
Which tail type should I prefer? Halfmoon tails should spread to around 180 degrees when flaring. A wider spread is aesthetic but may require calmer tanks to prevent fin damage from rough handling.
How should I introduce new bettas? Quarantine new arrivals for 1-2 weeks before mixing with established tanks to reduce disease risk and monitor color stability and appetite.
