🐠 Over Half-Moon Multicolor Male Betta

What It Is

The Over Half-Moon Multicolor Male Betta is a high-grade variety of Betta splendens (the Siamese fighting fish).

• “Half-Moon” describes the tail shape — when fully flared, the caudal (tail) fin spreads about 180°, forming a perfect semicircle.

• “Over Half-Moon” means the spread exceeds 180°, a sign of premium genetics and careful breeding.

• “Multicolor” means the fish displays three or more distinct colours, often including blues, reds, whites, and metallic hues.

• “Male” bettas are known for their large, flowing fins and stronger colours compared to females.

🔍 Key Features to Look For

1. Tail Spread – A perfect or slightly over-180° tail spread when the fish flares.

2. Fin Quality – Smooth, even webbing and symmetrical fins without tears or curling.

3. Colour Pattern –

   • Distinct multicolor blending (blue, red, yellow, white, or metallic tones).

   • Vibrant and well-defined patterns — marbles, koi, or butterfly patterns are common.

4. Body Condition – Straight spine, smooth scales, no bloating or indentations.

5. Behaviour – Active but not frantic, responsive to movement, fins held open (not clamped).

🏡 Tank Setup and Environment

• Tank Size: Minimum 10 litres (around 2.5 gallons) for one male. Larger is better.

• Temperature: 24–28 °C (75–82 °F).

• pH: Between 6.5 and 7.5, stable water preferred.

• Filtration: Gentle flow filter — strong currents can damage fins.

• Substrate and Decor: Smooth gravel or sand, soft plants (live or silk), and hiding spots like caves or driftwood. Avoid sharp decorations.

• Lighting: Moderate light, 8–10 hours daily.

• Cover: Keep a lid with air space — bettas breathe surface air using their labyrinth organ.

🍽️ Feeding and Diet

• Bettas are carnivorous.

• Feed high-quality betta pellets or flakes with protein content over 35%.

• Supplement with live or frozen foods: bloodworms, brine shrimp, or daphnia.

• Feed small amounts once or twice daily — only what the fish can eat in 1–2 minutes.

• Skip one feeding day per week to prevent bloating.

🧘 Temperament and Compatibility

• Male bettas are territorial — do not house two males together.

• Can coexist with very peaceful tank mates that don’t nip fins (e.g., small snails, corydoras, or certain shrimp).

• Avoid fast, fin-nipping fish like barbs or guppies.

• Keep stress low — stress dulls colours and weakens immunity.

💧 Health and Maintenance

• Water changes: 25–30% once per week.

• Monitor health: Watch for clamped fins, loss of colour, white patches, bloating, or lethargy.

• Common issues:

  • Fin rot – caused by poor water or injury; treat promptly.

  • Ich – white spots; treat with heat and medication.

  • Bloating / constipation – from overfeeding.

• Quarantine new fish for 1–2 weeks before adding to the main tank.

🎨 Colour and Pattern Notes

• Multicolor males often have shifting patterns — marble genes can cause the colours to change over time.

• Over Half-Moon types have heavy fins that may tear easily, so excellent water quality and calm surroundings are vital.

• A well-kept multicolor male often develops deeper and richer colours as it matures.

🛒 Buying Tips

• Inspect under good lighting — check tail spread, colour vibrancy, and fin edges.

• Avoid fish with torn fins, dull colours, or clamped fins.

• Ask about the age (young adults show best fin form).

• Always acclimate slowly to your tank’s temperature and water before release.

• Quarantine before adding to any shared tank.

• Healthy lifespan: typically 2–4 years, sometimes longer with good care.
