🐠 Over Half-Moon Betta Red Sky Hawk (Male)

🔹 Overview

The Over Half-Moon Betta Red Sky Hawk Male is a spectacular variation of Betta splendens, selectively bred for its vibrant red hues, powerful tail structure, and majestic fin symmetry.
The name “Red Sky Hawk” is typically a breeder or trade name used to describe bettas that display deep, fiery red tones resembling the colour of a sunset sky — paired with the dramatic “Over Half-Moon” tail spread.

  • “Over Half-Moon” → Tail spreads beyond 180°, often approaching a full circle when flared.

  • “Red Sky Hawk” → Refers to the intense red coloration, often metallic or glowing, with balanced body and fin proportions.

  • “Male” → Males show stronger colours, longer fins, and more elaborate displays compared to females.


🔹 Key Physical Traits

  1. Tail Shape – Extremely wide caudal (tail) fin, spreading more than 180°, creating a “fan” or “halo” effect when flared.

  2. Coloration

    • Dominant deep crimson or scarlet red across the fins and body.

    • May have slight gradients of orange, black, or metallic undertones near the fin edges.

    • Some Red Sky Hawks may have subtle iridescence on the body scales.

  3. Body – Streamlined and strong; males are typically 6–7 cm (2.5–3 inches) long.

  4. Fins – Broad, symmetrical fins that form a perfect round silhouette when viewed from the side.

  5. Eyes – Dark and expressive, usually matching or contrasting subtly with the red tone.


🔹 Behaviour and Temperament

  • Temperament: Territorial and aggressive toward other males. Best kept solo.

  • Personality: Confident and curious, often interacts with the owner by following hand movements.

  • Flaring: Displays fins and gills in a fan-like show — a natural, healthy behaviour used for communication or dominance.

  • Activity Level: Moderate — graceful swimmer with strong control despite large fins.


🔹 Tank Setup and Environment

Feature Ideal Setup
Tank Size Minimum 10 litres (2.5 gallons); ideally 20 litres or more
Temperature 24–28 °C (75–82 °F)
pH Level 6.5–7.5
Water Type Soft to moderately hard
Filtration Gentle, low-flow filter (strong currents stress fins)
Lighting Moderate light to highlight red tones; avoid glare
Substrate Fine sand or smooth gravel
Decor Silk or live plants, smooth stones, caves, driftwood
Cover Lid or cover required — bettas breathe air and can jump

Tip: Red varieties look best under neutral white or slightly warm lighting, which enhances the richness of their red pigment.


🔹 Feeding and Diet

  • Diet Type: Carnivorous.

  • Staple Foods: High-protein betta pellets or micro-granules (35–45% protein).

  • Supplementary Foods: Live or frozen treats like brine shrimp, bloodworms, daphnia, and mosquito larvae.

  • Feeding Schedule:

    • Feed 1–2 small meals daily.

    • Give only what the fish can eat within 2 minutes.

    • Skip feeding once a week to prevent bloating.

  • Avoid: Overfeeding, plant-based foods, and poor-quality pellets that cause water pollution.


🔹 Health and Maintenance

Common Health Issues:

  1. Fin Rot: Caused by dirty water or fin injury; maintain cleanliness.

  2. Bloating/Constipation: Prevented by fasting and balanced feeding.

  3. Fin Tear: Heavy fins can tear easily — avoid sharp décor and strong filter flow.

  4. Stress or Fading Color: Triggered by poor water conditions or aggressive tank mates.

  5. Velvet/Ick: Monitor for gold or white specks on the body; treat promptly.

Care Tips:

  • Change 25–30% of tank water weekly.

  • Keep temperature and pH stable.

  • Observe colour and fin condition daily.

  • Provide resting spots near the surface (broad leaves or smooth decorations).

  • Do not use mirrors constantly — flaring is healthy in moderation but tiring if overdone.


🔹 Compatibility

  • Best Kept Alone: Males are highly territorial.

  • Possible Tank Mates:

    • Peaceful bottom dwellers (corydoras, kuhli loaches).

    • Small snails (nerite or mystery snails).

    • Some shrimp (if large and not harassed).

  • Avoid:

    • Any fin-nipping or fast species (barbs, guppies, tetras).

    • Other bettas unless tank is divided.


🔹 Lifespan

  • Average: 2–4 years.

  • Maximum: Up to 5 years with excellent care and stable conditions.

  • A balanced diet, clean water, and minimal stress extend their lifespan.


🔹 Breeding Information (for experienced keepers)

  • Type: Bubble nest builder.

  • Male Role: Builds bubble nest, guards eggs, and tends fry.

  • Female: Introduced only for breeding, then removed after spawning.

  • Difficulty: Moderate to high — Red Sky Hawk males are sensitive and require calm, warm breeding conditions.

  • Caution: Avoid overbreeding or pairing with weak females; selective breeding maintains quality and health.


🔹 Why They’re Special

  • The Red Sky Hawk stands out for its deep, rich red hue — a symbol of energy, passion, and strength.

  • Its Over Half-Moon tail gives a regal, fan-like display unmatched by simpler fin types.

  • The vibrant red against clear water and plants creates a striking visual centerpiece in any aquarium.

  • Each male exhibits slightly different red tones — some deeper like crimson, others fiery like molten orange-red — making each fish unique.
