The Halfmoon Betta, prized for its stunning 180-degree tail, is highly sought after by European importers who demand exceptional quality. Since 2012, THIENDUC AQUARIUM has specialized in exporting world-class ornamental fish from Vietnam. Our rigorous quality control ensures healthy, premium fish, reduces Dead on Arrival (DOA) rates, and builds lasting trust with our partners. This is our commitment to every Halfmoon Betta for Export.

Understanding the Ideal Halfmoon Betta Standard

To select the best, one must first understand the ideal. The Halfmoon Betta is judged against a strict set of standards that define its grade and value. It's a harmonious blend of genetic perfection and pristine conditioning.

The Defining Trait: The Caudal Fin (Tail)

The name "Halfmoon" comes directly from the fish's most stunning feature: its tail. When the fish flares, the caudal fin must spread to a perfect 180 degrees, creating a flawless "D" shape. The edges of this "D" must be sharp and straight, not frayed, rounded, or uneven. This perfect semi-circle is the single most important characteristic of a top-grade Halfmoon.

Overall Symmetry & Proportion (The "Balance")

A quality Halfmoon Betta is a portrait of balance. The fish should appear harmonious and well-proportioned from every angle. When viewed from the side, the outline of the caudal (tail), dorsal (top), and anal (bottom) fins should combine to form a rough circle or oval. This symmetry is what separates a good fish from a truly exceptional one.

Detailed Finnage Analysis

Beyond the caudal fin, every fin plays a role in the fish's overall presentation:

• Dorsal Fin (Top): It should possess a broad base and substantial volume, visually mirroring the anal fin to contribute to the overall circular silhouette.

• Anal Fin (Bottom): The leading edge should be clean and straight, running parallel to the dorsal fin's shape, enhancing the fish's balanced look.

• Ventral Fins (Paired, under the gills): These should be elegant and simple—a single, sharp prong on each side, uniform in length, and not excessively long, twisted, or curled.

• Pectoral Fins (Side): Often called the "ears," these should be clear, well-formed, and actively used by the fish for maneuvering.

Body Shape & Condition

The foundation for these spectacular fins is a strong, healthy body. The ideal shape is a smooth, robust torpedo that tapers elegantly towards the tail. There should be absolutely no deformities, such as a bent spine, a sunken or bloated belly, or a head that is disproportionately large for its body.

Key Selection Criteria for Export-Grade Fish

At THIENDUC AQUARIUM, every fish is scrutinized against four key criteria. This ensures that our clients in the UK, France, Germany, the Netherlands, and across the EU receive only the most viable and valuable specimens.

Criterion 1: Health & Vitality (Non-negotiable)

Before any aesthetic evaluation, we conduct a rigorous health assessment. A beautiful fish is worthless if it cannot survive the journey or thrive in its new home. Selecting a healthy Halfmoon Betta for Export is the foundational first step.

• Behavior: We look for active and curious fish. A healthy Betta is aware of its surroundings, reacts to stimuli, and displays its fins with confidence. It should flare aggressively at a mirror or a neighboring male, a clear sign of vigor.

• Signs of Sickness to AVOID: We immediately disqualify any fish showing lethargy, clamped fins (held tightly against the body), visible parasites like Ich (white spot), fungal growths, fin rot, bloating, or rapid, stressed breathing.

Criterion 2: Conformation to Breed Standards (The "Grade")

This is the technical evaluation of the fish's physical form against the ideals mentioned above. Our standards for Halfmoon Betta for Export demand near-perfect conformation.

• Tail Spread: Does the fish consistently achieve a 180° spread without strain? We use controlled environments and lighting to see the fin's full potential.

• Fin Edges: Are the fin edges crisp, clean, and sharp? Any indication of splitting, curling, or "melting" (thinning edges) is a serious fault.

• Symmetry Check: We assess the fish's balance meticulously. Is the dorsal fin as well-developed as the anal fin? Is the contour of the body perfect? Only the most symmetrical fish make our top grade.

Criterion 3: Coloration & Pattern

For the European market, color is king. A fish's visual appeal is its primary selling point. The vibrant coloration is a key selling point for any Halfmoon Betta for Export.

• Vibrancy: Colors must be deep, rich, and solid, appearing as if they are painted on. A washed-out color is a sign of poor genetics or health.

• Clarity: In patterned fish like Koi, Nemo, or Galaxy varieties, the separation between colors must be sharp and distinct.

• Consistency: The color should be uniform across the body and fins. We check for undesirable traits like "red wash" in a blue fish, which diminishes its value.

Criterion 4: Age & Size

The age and size of a Betta are critical for its successful export and long-term health. At THIENDUC AQUARIUM, we carefully manage the age of every Halfmoon Betta for Export.

• Optimal Age: The ideal age for export is between 3.5 and 6 months. At this stage, the fish is mature enough to display its full genetic potential (color and finnage) but still young and robust enough to handle the stress of shipping and acclimate well to a new environment.

• Size: A well-proportioned body size for its age is a strong indicator of good health and proper care during its crucial development phase.

The Practical Selection Process at THIENDUC AQUARIUM

Our selection process is methodical and designed to ensure consistency and quality. Each potential Halfmoon Betta for Export is evaluated individually.

• Step 1: Initial Mass Screening: Our trained staff first scan large batches of fish, quickly identifying and removing any individuals with obvious health problems or severe physical deformities.

• Step 2: Individual Assessment: Promising candidates are moved to individual, clear containers for close-up evaluation, a practice known as "jarring." This allows us to observe their natural behavior and induce flaring with a mirror to assess their conformation against our rigorous standards.

• Step 3: Grading: Based on the assessment, fish are categorized into grades (e.g., Grade A/Show Grade, Grade B/Export Grade). The top-grade fish are then photographed for our catalogs and online listings, providing our clients with a clear view of the quality they can expect. This rigorous process guarantees a premium batch of Halfmoon Betta for Export.

Pre-Export Conditioning: Ensuring a Safe Arrival

Selecting a great fish is only half the battle. Ensuring it arrives in pristine condition after a long flight to Europe is a science. Proper conditioning is vital for the successful journey of a Halfmoon Betta for Export to the EU. Before packing, every fish undergoes a critical conditioning phase. This includes fasting for 24-48 hours to minimize waste production in the shipping bag and housing them in clean, specially conditioned water with natural additives like tannins to reduce stress.
