Betta fish, also known as Siamese fighting fish, are among the most popular aquarium species due to their vibrant colors, striking fins, and unique personalities. Native to Southeast Asia, these freshwater fish belong to the Osphronemidae family and thrive in shallow waters like rice paddies and slow-moving streams. Over centuries of selective breeding, bettas have evolved into a diverse array of types, each with distinct physical traits. Below, we explore the most iconic betta fish varieties and their characteristics.
1. Tail and Fin Morphology-Based Varieties
The shape and size of their fins and tails are the primary features used to classify bettas. Here are the key categories:
Veil Tail (VT)
The most common type, recognized by its long, flowing tail that droops downward like a veil. Though less exotic compared to newer breeds, its affordability and wide availability make it a beginner favorite.
Crowntail (CT)
Identified by spiky, comb-like fins resembling a crown. The rays extend beyond the fin membrane, creating a dramatic, jagged appearance. Crowntails are prized for their bold, almost metallic hues.
Halfmoon (HM)
Named for its tail that forms a perfect 180-degree semicircle when flared. Halfmoons often exhibit iridescent scales and are highly sought after in competitions for their symmetry and vibrant coloration.
Plakat (PK)
Resembling wild bettas, Plakats have short, rounded tails and sturdy bodies. Originally bred for fighting, they are agile swimmers and less prone to fin damage than long-finned varieties.
Delta/Super Delta (SD)
Delta bettas have tails that widen toward the edge but don’t reach the full 180-degree spread of Halfmoons. Super Deltas fall just short of the Halfmoon classification, making them a transitional category.
Double Tail (DT)
A genetic mutation splits the caudal fin into two distinct lobes, giving the appearance of two tails. Double Tails often have shorter bodies and are bred for their unique symmetry.
Elephant Ear/Dumbo
Notable for their oversized pectoral fins that resemble elephant ears, these bettas glide gracefully through water. Their "wings" often contrast beautifully with their body colors.
2. Color and Pattern Varieties
Bettas are further categorized by their coloration and scale patterns:
Solid Color
These bettas display a single, uniform color across their body and fins. Classic shades include red, blue, and turquoise, while rare hues like pure white (Cellophane) or black (Melano) are highly coveted.
Marble
Marble bettas boast irregular, blotchy patterns caused by a jumping gene that disrupts pigmentation. Their colors may shift throughout their lives, adding an element of surprise for owners.
Butterfly
Characterized by a solid body color with fins that transition into a contrasting shade (often white or translucent) at the edges. The clean, layered effect resembles butterfly wings.
Koi
Inspired by koi carp, these bettas feature a mix of red, white, and black patches. Newer variations include "Galaxy Koi" with metallic speckles resembling stardust.
Metallic/Steel
Scales with a metallic sheen, often in turquoise, copper, or steel-blue tones. The Dragon Scale variety has thick, armor-like scales that may cover parts of the face and fins.
Piebald
Piebald bettas have a pale, flesh-colored face contrasted against a darker body—a striking trait often paired with any tail type.
3. Specialized Hybrids
Modern breeding has led to experimental crosses, such as:
Rosetail/Feathertail: Extreme branching of fin rays creates a ruffled, feather-like texture.
Mask: A gene removes body coloration, leaving the face vibrant while the body appears lighter.
Alien: A hybrid of wild and domestic bettas, featuring iridescent scales and unique fin shapes.
Caring for Bettas: Quick Tips
While visually stunning, many fancy bettas (e.g., Halfmoons, Rosetails) are prone to fin damage and require meticulous care:
Tank size: Minimum 5 gallons with gentle filtration.
Water quality: Maintain a temperature of 76–82°F and pH 6.5–7.5.
Diet: Protein-rich foods like brine shrimp or specialized pellets.
Tankmates: Avoid housing males together; females can sometimes live in groups (sororities).
Conclusion
From the regal Halfmoon to the whimsical Dumbo, betta fish offer endless diversity for aquarists. Their resilience and beauty make them ideal for both novice and experienced fishkeepers. By understanding their unique needs and appreciating their rich variety, enthusiasts can ensure these living jewels thrive in their aquatic homes. Whether you’re drawn to their vivid colors or dramatic fins, there’s a betta variety to captivate every aquarist’s heart.
