When it comes to betta fish, also known as Betta splendens, the diversity is both vast and spectacular. Whether you are a seasoned aquarist or a novice just embarking on your aquatic journey, understanding the myriad types of betta fish can greatly enhance your decision-making process when selecting the perfect betta for your tank. Though all betta fish share the same scientific classification, their various appearances and characteristics stem from centuries of selective breeding and hybridization. In this detailed guide, we will delve into the different types of betta fish, their distinctive traits, and what makes each variety unique and captivating.
1. Male vs. Female Betta Fish: Understanding the Differences
Before diving into the specifics of the various betta fish types, it’s essential to understand the fundamental differences between male and female bettas. This foundational knowledge will help you appreciate the nuances of each type.
- Male Bettas: Male bettas are renowned for their eye-catching appearance and dramatic fins. They typically possess larger, more elaborate fins and exhibit a more aggressive demeanour, particularly when confronted with other males or their reflections. The extensive, colourful fins of male bettas are not only a visual delight but also play a crucial role in their natural behaviours, such as courtship and territory establishment. These fins are designed to capture attention and assert dominance in the wild.
- Female Bettas: Female bettas, on the other hand, are usually smaller and less ornate than their male counterparts. They tend to have shorter fins and a more streamlined body, which makes them less aggressive. Females often exhibit a more subdued colouration compared to males. Additionally, females may show a rounded abdomen, especially when they are carrying eggs, which is a clear indicator of their reproductive readiness. While they are generally less aggressive, female bettas can display a range of temperaments depending on their environment and individual personality.
2. Halfmoon Betta
The Halfmoon betta is perhaps one of the most well-recognized and sought-after types in the betta world. Its name derives from the striking shape of its tail.
- Appearance: The defining feature of the Halfmoon betta is its tail, which fans out to form a perfect 180-degree semicircle. This tail shape is reminiscent of a half-moon or a ‘D’ shape when fully extended. The dorsal fin (located on the fish’s back) and the anal fin (located underneath near the tail) are also notably extended and ideally overlap with the edges of the tail, contributing to the fish’s overall majestic appearance. This expansive tail and fin structure is a result of selective breeding aimed at enhancing its visual appeal.
- Key Features: The Halfmoon betta’s most prominent feature is its impressive tail spread, which can extend up to a full 180 degrees, creating a semi-circular shape. This characteristic makes it a popular choice among betta enthusiasts who appreciate its grandeur and dramatic flair.
- Tank Recommendations: Due to its large fins, the Halfmoon betta requires a spacious tank. This allows the fish to fully display its beautiful tail and move freely without restriction. It is also essential to ensure that the tank is free from sharp objects that could damage its delicate fins.
3. Crowntail Betta
The Crowntail betta stands out due to its unique tail structure, which resembles a crown.
- Appearance: The Crowntail betta is characterized by its distinctive tail, where the webbing between each fin ray is significantly reduced. This creates a spiky, crown-like appearance on the tail, dorsal, and anal fins. There are various types of ray extensions, including single ray, double ray, and cross ray, each adding a different dimension to the betta’s appearance. The reduced webbing gives the Crowntail its signature spiky look, making it a visually striking choice.
- Key Features: The primary feature of the Crowntail betta is its spiky appearance, which results from the reduced webbing between fin rays. This distinctive trait, along with the different types of ray extensions, makes the Crowntail betta a popular choice among fish enthusiasts.
- Tank Recommendations: To keep the Crowntail betta in optimal condition, it’s important to provide a tank with smooth decorations and high water quality. Sharp objects can easily damage the delicate fins, so a well-maintained tank environment is crucial.
4. Plakat Betta
The Plakat betta is known for its shorter fins and streamlined body, a throwback to its origins as a fighting fish.
- Appearance: Unlike the long-finned varieties, the Plakat betta has much shorter fins and a more compact body, which allows it to swim swiftly through the water. This design was originally intended to enhance its agility during fights. The anal fin of the Plakat is less rectangular and somewhat pointed, in contrast to the longer, billowy fins of other bettas. Plakats often feature longer ventral fins (the two fins located under the chin) compared to other types.
- Key Features: The Plakat betta’s shorter fins and streamlined body are its most distinguishing features. These traits give it a sleek, agile appearance and contribute to its swiftness in the water.
- Tank Recommendations: Due to its more compact size and active nature, the Plakat betta is well-suited for smaller tanks. However, it still needs ample space to swim and thrive, as well as a well-maintained environment to keep its fins in good condition.
5. Giant Betta
The Giant Betta is a variant of the Plakat betta and is distinguished by its impressive size.
- Appearance: Unlike standard bettas, Giant Bettas continue to grow throughout their life, reaching lengths of over 2.5 inches (6.35 cm) for males. They have a robust and hefty appearance, which sets them apart from the smaller bettas. The increased size contributes to their striking presence in an aquarium.
- Key Features: The Giant Betta’s most notable feature is its larger size compared to typical bettas. This robust body mass gives the fish a commanding presence and makes it a focal point in any aquarium.
- Tank Recommendations: Due to its larger size, the Giant Betta requires a spacious tank to accommodate its growth and active swimming habits. Providing a well-maintained environment is essential to ensure its health and well-being.
6. Doubletail Betta
The Doubletail betta is unique for its distinctive tail structure, which consists of two separate lobes.
- Appearance: The Doubletail betta’s tail is divided into two separate lobes that connect directly to the fish’s body, creating a distinctive double-tail effect. The body profile of a Doubletail betta is generally shorter and stouter to support the two tails. This form can be found in various types, including Halfmoon, Plakat, and Crowntail.
- Key Features: The defining characteristic of the Doubletail betta is its unique tail structure, which resembles two separate tails. This feature gives the fish a distinctive and striking appearance.
- Tank Recommendations: The Doubletail betta needs a larger tank to accommodate its body structure and ensure it has enough space to swim comfortably. Care should be taken to maintain a clean environment to prevent any damage to its unique tail.
7. Veiltail Betta
The Veiltail betta is one of the classic forms and is known for its elegant, flowing tail.
- Appearance: The tail of the Veiltail betta has a drooping, teardrop shape, with a bulbous base that tapers to a pointed tip. The dorsal fin is narrow and blade-like, while the anal fin is trapezoidal in shape, with the front edge shorter than the back edge. This form has been around for a long time and remains a popular choice for its graceful appearance.
- Key Features: The Veiltail betta’s elegant tail and classic shape make it a timeless favorite among betta enthusiasts. Its flowing fins and graceful appearance contribute to its enduring popularity.
- Tank Recommendations: Ideal for tanks where the long fins can be displayed without obstruction. A clean, well-maintained tank is essential to prevent any damage to the delicate fins.
8. Elephant Ear Betta
The Elephant Ear betta is characterized by its large, prominent pectoral fins, which give it a distinctive look.
- Appearance: The Elephant Ear betta has notably enlarged pectoral fins that resemble the ears of an elephant. This feature can be combined with various tail types and colours, making each Elephant Ear betta unique. The enlarged fins can be prone to splitting, so care must be taken to ensure the tank environment supports their well-being.

- Tank Recommendations: A tank with smooth decorations and high water quality is ideal to prevent damage to the delicate pectoral fins. Regular maintenance and monitoring of water conditions are crucial for the health of this betta variety.
9. Alien Betta
The Alien betta is a hybrid that combines the colour traits of domesticated bettas with the slender body of wild-type betta species.
- Appearance: The Alien betta features a slender body with dark, thick banding or bars on the fins. It often comes in iridescent colours, ranging from blue to green, with a contrasting non-black face. This unique combination of traits results in a visually striking and exotic appearance.

Betta fish are renowned for their stunning array of colours and patterns, each adding to their beauty and appeal.
- Single Color: These bettas have a uniform colour throughout their body and fins. Common colours include red, blue, yellow, and white. The simplicity of a single-color betta can be striking in its own right.
- Bicolor: Bicolor bettas feature two distinct colours, with the body and fins in separate hues. This contrast can create a visually appealing and balanced look.
- Butterfly: Butterfly bettas have a banded pattern on their fins, with distinct colour bands separated by clear lines. The body colour does not have to match the inner band, adding to the pattern’s uniqueness.
- Marble: Marble bettas display a pattern of high-contrast dots or patches, which can change as the fish matures. This ever-changing pattern makes marble bettas particularly intriguing.
- Dalmatian: The Dalmatian betta has a solid-coloured body with evenly distributed spots on the fins and tail. This pattern gives it a distinctive and eye-catching appearance.
- Multicolor: Multicolor bettas exhibit three or more colours arranged in a pleasing pattern. The colours do not have to be evenly distributed, but the overall effect should be visually appealing.
- Orchid: Orchid bettas are strikingly all-black with a splash of accent colour between the fin rays. The contrast between the black body and vibrant accents creates a stunning visual effect.
- Dragon: Dragon bettas are characterized by their thick, metallic scales that resemble dragon armour. Sometimes they develop a condition known as “diamond eye,” where the scales can cover one or both eyes, leading to blindness.
