🐠 Over Half-Moon Betta Rosetail Male

🔹 Overview

The Over Half-Moon Betta Rosetail Male is a selectively bred variety of Betta splendens (Siamese fighting fish).
It’s one of the most spectacular and ornate forms, famous for its massive, flowing fins and “rose-like” tail pattern.

• “Half-Moon”: Refers to the tail that spreads 180° when flared.

• “Over Half-Moon”: Means the tail extends beyond 180°, often forming a near-perfect circle.

• “Rosetail”: Describes extra fin branching and overlapping rays that make the tail resemble rose petals — highly decorative and ruffled.

• “Male”: Males show the most vibrant colours and longest fins, making them the stars of this variety.

🔹 Key Physical Traits

1. Tail Shape – Wide, rounded fan exceeding 180°, often overlapping like rose petals.

2. Fins – Very long, flowing, and delicate. The dorsal and anal fins are large and balanced with the caudal fin.

3. Body Size – Typically 5–7 cm (2–2.75 in) in body length, excluding fins.

4. Colours – Found in solid, bicolour, marble, koi, and multicolour patterns. Metallic tones (copper, turquoise, gold) are also common.

5. Unique Look – When fully flared, the Rosetail male looks like a flower in motion, with shimmering layers of fins.

🔹 Behaviour and Personality

• Temperament: Territorial and solitary. Males will fight each other if housed together.

• Activity Level: Graceful but slower swimmers due to the heavy fins.

• Interaction: Recognizes owners, may come to the surface for food or attention.

• Flaring: Displays fins and gills to assert dominance or show off — a natural behaviour that keeps muscles strong.

🔹 Tank and Environment

• Tank Size: At least 10 litres (2.5 gallons) per fish; 20 litres or more preferred for comfort and stability.

• Temperature: 24–28 °C (75–82 °F).

• pH: 6.5–7.5.

• Filtration: Gentle filtration — strong flow can tear fins or exhaust the fish.

• Substrate: Smooth sand or small gravel.

• Decor: Soft plants (live or silk), caves, driftwood, and smooth surfaces for resting. Avoid sharp decorations.

• Lighting: Moderate light; enhance colours but avoid excessive brightness.

• Cover: Use a lid or cover — bettas breathe air at the surface and may jump.

🔹 Feeding and Diet

• Diet Type: Carnivorous.

• Staple Foods: High-protein betta pellets or flakes.

• Supplements: Live or frozen foods — brine shrimp, bloodworms, daphnia, mosquito larvae.

• Feeding Frequency: 1–2 small meals daily; only what can be eaten in about 2 minutes.

• Fasting Day: Skip one feeding day per week to prevent bloating.

🔹 Health and Maintenance

Because of the Rosetail’s extra-long fins, special care is needed:

Common Issues:

1. Fin Rot: Caused by poor water quality or injury — treat early and maintain clean water.

2. Tail Damage: Heavy fins tear easily; avoid sharp décor and rough handling.

3. Fin Curling: Can result from too strong a current, poor diet, or cold water.

4. Swim Fatigue: The large fins can slow swimming — avoid deep or turbulent tanks.

5. Bloating / Constipation: From overfeeding or improper diet; feed sparingly and include frozen daphnia occasionally.

Maintenance Tips:

• Change 25–30 % of water weekly.

• Keep temperature stable — avoid sudden drops.

• Test water regularly for ammonia, nitrite, and nitrate.

• Observe fins and colour daily; early signs of illness are easier to treat.

🔹 Compatibility

• Keep one male per tank unless divided.

• Can share space with peaceful, slow fish or snails/shrimp, provided they don’t nip fins.

• Avoid barbs, guppies, tetras, or any fin-nipping or active species.

• Females or other bettas should only be kept with males in carefully managed breeding or divided setups.

🔹 Breeding Notes

• Breeding Rosetails is delicate — they are often prone to genetic deformities due to excessive fin branching.

• Breeders select only strong, healthy pairs to prevent weak fry.

• Males build bubble nests and care for eggs, but breeding should be done by experienced aquarists only.

🔹 Lifespan

• Average 2–4 years, occasionally up to 5 with excellent care.

• Proper diet, clean water, and stable temperature significantly increase longevity.

🔹 Why They’re Special

• The Over Half-Moon Rosetail Male is one of the most visually dramatic bettas.

• Its oversized, ruffled fins give it a royal and elegant appearance.

• Each fish is unique in colour and pattern — no two Rosetails are identical.

• They are ideal as solo display fish in aquariums where their beauty can be the main focus.
