Few aquarium fish display as much visual diversity as the Betta.
Domestic Betta Fish (Betta splendens), commonly called Siamese Fighting Fish, can have enormous fan-shaped tails, spiky crown-like fins, compact plakat bodies, metallic scales, koi-like patches, solid jewel tones, or combinations of several traits at once.
That variety can make Betta terminology confusing.
A “Halfmoon,” for example, describes a tail form. A “koi” Betta describes a color pattern. A “dragon scale” describes a scale and pigmentation trait. A single fish could potentially be a Halfmoon, koi, and metallic Betta at the same time.
So rather than thinking of every name as a separate Betta breed, it is more useful to understand the major categories breeders and aquarists use to describe them.
This guide covers the most popular Betta tail types, colors, patterns, scale varieties, and unusual forms—and explains what those differences mean for aquarium care.

🔬 What Species Are Pet Bettas?
Most colorful Bettas sold in aquarium stores are domestic forms of:
Betta splendens
Wild Betta splendens looks quite different from many ornamental strains.
The exaggerated fins, intense colors, unusual patterns, and massive range of modern forms are largely the result of selective breeding.
Bettas have been domesticated for centuries, first particularly for fighting behavior and later increasingly for ornamental traits such as:
- Fin length
- Tail shape
- Body size
- Color
- Pattern
- Metallic scales
- Enlarged pectoral fins
Modern genetic research has also shown that domestic Betta lines have a complicated ancestry that includes historical introgression from related wild Betta species.
In other words, today’s ornamental Betta is the product of a very long and complex breeding history.
🧬 Betta “Breeds” vs. Types and Varieties
The word breed is widely used in the aquarium hobby, but it can be misleading when discussing Bettas.
Most names describe one particular visible characteristic rather than a genetically isolated breed.
For example:
Halfmoon = tail shape
Crowntail = fin structure
Plakat = short-fin body form
Koi = color pattern
Dragon Scale = scaling/pigmentation
Dumbo = enlarged pectoral fins
Giant = body-size form
These traits can overlap.
A fish could therefore be described as a:
Koi Halfmoon Betta
or:
Dragon Scale Plakat Betta
or:
Dumbo Halfmoon Betta
Understanding this makes the enormous list of Betta names much easier to navigate.
🎏 Popular Betta Tail Types at a Glance
| Tail Type | Main Feature |
|---|---|
| Veiltail | Long, asymmetrical downward-flowing tail |
| Halfmoon | Tail spreads approximately 180° when fully flared |
| Delta | Broad triangular tail with less than a Halfmoon’s spread |
| Super Delta | Wider than a Delta but not a full Halfmoon |
| Crowntail | Reduced webbing creates spiky fin rays |
| Combtail | Mildly reduced webbing; less extreme than Crowntail |
| Doubletail | Caudal fin divided into two distinct lobes |
| Plakat | Short-finned form |
| Halfmoon Plakat | Short fins with broad Halfmoon-type caudal shape |
| Rosetail | Heavy branching produces an extremely ruffled tail |
| Roundtail | Rounded caudal fin |
| Dumbo/Elephant Ear | Enlarged pectoral fins rather than a true tail type |
Let’s look at these forms individually.
👰 Veiltail Betta
The Veiltail is one of the oldest and most familiar ornamental Betta forms.
Its caudal fin is:
- Long
- Flowing
- Asymmetrical
- Usually carried downward behind the body
When the fish swims, the tail drapes behind it almost like fabric.
Veiltails became extremely common in pet stores because their flowing finnage is attractive and the form became well established in commercial breeding.
They can occur in almost every Betta color and pattern.
For a deeper look at this classic variety, see our Veiltail Betta Fish guide.
🌙 Halfmoon Betta
The Halfmoon Betta is one of the most prized ornamental forms.
When fully flared, the tail opens to approximately 180 degrees, creating the shape of a semicircle.
A well-formed Halfmoon typically has:
- Broad caudal fin
- Strong fin rays
- Relatively symmetrical upper and lower tail edges
- Large dorsal and anal fins
Halfmoons can be found in virtually every color and pattern.
Examples include:
- Red Halfmoon
- Blue Halfmoon
- Koi Halfmoon
- Butterfly Halfmoon
- Dragon Halfmoon
- Black Halfmoon
Their enormous fins are spectacular, but they also create more drag than the compact fins of a Plakat.
Gentle filtration is especially useful for long-finned Bettas.
🔺 Delta Tail Betta
A Delta Betta has a broad triangular caudal fin that widens from the base toward the outer edge.
When flared, the shape resembles the Greek letter delta.
The tail does not open to the full 180-degree spread expected of a Halfmoon.
Delta Bettas provide much of the dramatic broad-tail appearance without requiring the extreme spread of a competition-style Halfmoon.
📐 Super Delta Betta
The Super Delta falls between the Delta and Halfmoon.
Its tail spreads very widely but stops short of the approximately 180-degree Halfmoon shape.
For many pet Bettas, the distinction between Delta, Super Delta, and imperfect Halfmoon can be somewhat subjective unless the fish is being evaluated under formal show standards.
👑 Crowntail Betta
The Crowntail Betta is instantly recognizable.
Instead of having webbing extending fully between the fin rays, portions of the webbing are reduced.
The exposed rays extend outward like:
- Spikes
- Crown points
- Fringes
The effect may appear on the:
- Tail
- Dorsal fin
- Anal fin
Crowntails come in both long- and short-finned forms.
Their dramatic silhouette makes them one of the easiest Betta types to identify.
🪮 Combtail Betta
A Combtail has extended fin rays similar to a Crowntail, but the effect is less extreme.
The webbing reduction creates a comb-like edge rather than the deeply separated spikes of a strong Crowntail.
Combtails can sometimes arise from crosses involving Crowntails and more fully webbed fin types.
✌️ Doubletail Betta
The Doubletail Betta has a caudal fin divided into two separate lobes.
Instead of one tail fan, the fish appears to have an upper and lower tail.
Doubletail Bettas often also develop:
- Broader dorsal fins
- Compact body proportions
- Increased fin symmetry
The Doubletail trait has been investigated genetically and is associated with developmental changes that affect tail and body morphology.
Doubletail Bettas can be visually spectacular, particularly when combined with Halfmoon-type finnage.
🏃 Plakat Betta
The Plakat Betta is the major short-finned domestic form.
Compared with long-finned ornamental males, Plakats have:
- Shorter caudal fins
- Shorter anal fins
- More compact finnage
- A more athletic swimming style
Their appearance is closer to the basic short-finned shape of wild Bettas and traditional fighting strains.
Today, however, ornamental Plakats can be every bit as colorful as long-finned Bettas.
Popular examples include:
- Koi Plakat
- Galaxy Plakat
- Dragon Plakat
- Nemo Plakat
- Copper Plakat
- Black Plakat
Plakats have become especially popular with aquarists who enjoy dramatic colors but prefer a fish without enormous trailing fins.
🌙 Halfmoon Plakat
The Halfmoon Plakat, often abbreviated HMPK, combines short fins with a broad tail designed to approach the Halfmoon form.
These fish tend to have:
- Compact bodies
- Strong swimming ability
- Broad caudal fins
- Sharp visual symmetry
HMPKs are extremely popular among ornamental breeders.
Many modern koi, galaxy, Nemo, metallic, and fancy Bettas are sold in Halfmoon Plakat form.
🌹 Rosetail Betta
A Rosetail Betta develops unusually heavy branching of the fin rays.
The result is an enormous ruffled tail with overlapping folds resembling rose petals.
Some Rosetails can look spectacular when fully flared.
However, increasingly excessive finnage is not automatically better for the fish.
Extremely elaborate fins can create considerable swimming resistance and may be more susceptible to:
- Tearing
- Damage
- Fatigue
- Fin deterioration
When choosing any very heavily finned Betta, prioritize a healthy fish that can swim normally over the most exaggerated appearance possible.
🌸 Feathertail Betta
Feathertails take heavy branching beyond the Rosetail look.
Their fins may appear:
- Extremely ruffled
- Feathered
- Highly branched
- Uneven around the edges
The dramatic appearance can come with the same practical concerns as extreme Rosetails.
Very elaborate finnage should never compromise basic mobility.
⚪ Roundtail Betta
Roundtail Bettas have a caudal fin with a smooth, rounded outer edge.
The shape is less angular than a Delta and less expansive than a Halfmoon.
It can create a simple, balanced silhouette that is particularly attractive in short-finned fish.
🐘 Dumbo or Elephant Ear Betta
The Dumbo Betta, also known as the Elephant Ear Betta, is technically defined by its pectoral fins rather than its tail.
These fish have unusually large pectoral fins on either side of the head.
The fins can resemble:
- Ears
- Wings
- Fans
Modern genetic research has identified a major genetic basis underlying this enlarged pectoral-fin phenotype.
Dumbo Bettas can also be:
- Halfmoon
- Plakat
- Crowntail
- Doubletail
because the Dumbo trait can occur alongside different tail forms.
📏 Giant Betta
A Giant Betta is selected for increased body size rather than a particular fin shape or color.
International Betta Congress classes recognize Giant forms separately from standard-sized Bettas.
Giant Bettas can become noticeably larger and heavier-bodied than ordinary domestic Betta splendens.
Because of that additional size, I would give them more aquarium room rather than treating them exactly like a standard small male.
A 10-gallon or larger aquarium is an excellent choice for a Giant.
🎨 Popular Betta Fish Colors
Fin shape is only half of the Betta story.
Selective breeding has also created an extraordinary palette of body colors.
Common colors include:
- Red
- Blue
- Royal blue
- Steel blue
- Turquoise
- Green
- Yellow
- Orange
- Black
- White
- Copper
- Metallic
- Lavender
- Pastel
- Cellophane
Some colors are produced by pigments, while the shimmering blue and green tones involve reflective cells called iridophores.
The interaction of multiple pigment and reflective layers helps create the extraordinary visual range seen in domestic Bettas.
For an even deeper dive, see The Vibrant World of Betta Fish Colors.
❤️ Red Betta
Red is one of the classic Betta colors.
It can range from:
- Bright scarlet
- Cherry red
- Orange-red
- Deep crimson
Red may occur as a solid body color or as part of:
- Koi patterns
- Butterflies
- Bicolors
- Multicolor strains
Strong uniform red coloration is particularly dramatic on Halfmoon and Plakat males.
💙 Blue Betta
Blue Bettas can display several visually distinct shades.
Common descriptions include:
- Steel blue
- Royal blue
- Turquoise-blue
Their appearance can change substantially depending on aquarium lighting.
Structural coloration produced by reflective cells gives blue Bettas the shimmering quality that makes them appear almost metallic.
💚 Green and Turquoise Bettas
True-looking green coloration can be surprisingly striking in Bettas.
Many green individuals display strong iridescence and may shift visually between:
- Green
- Turquoise
- Blue-green
depending on the light angle.
🖤 Black Betta
Black Bettas are bred in several lines and patterns.
Examples include fish described as:
- Melano
- Black orchid
- Black copper
- Black dragon
Some are nearly solid black, while others combine deep black pigmentation with:
- Metallic scales
- Blue highlights
- White fin edging
- Iridescent accents
🤍 White Betta
White Bettas can range from opaque white to pale pearlescent shades.
Some have a clean, solid appearance.
Others show:
- Metallic sheen
- Iridescence
- Faint pastel coloration
Opaque white fish can be particularly striking when paired with black or dark aquarium backgrounds.
💛 Yellow Betta
Yellow Bettas range from light lemon to intense golden tones.
Yellow can occur as:
- Solid color
- Bicolor fins
- Koi pattern components
- Butterfly patterns
Yellow is also frequently seen alongside blue or dark bodies in combinations commonly marketed as Mustard Gas.
🧡 Orange Betta
Orange Bettas may range from:
- Pale tangerine
- Bright orange
- Deep orange-red
Modern genetic research has identified major genomic regions associated with differences among red, yellow, and orange ornamental Betta coloration.
🪙 Copper Betta
Copper Bettas have a strong metallic sheen.
Depending on lighting, they may appear:
- Copper
- Silver
- Bronze
- Blue-gray
- Greenish metallic
The color is caused by interactions involving iridescent and metallic traits.
Copper coloration is particularly dramatic on Plakat and Halfmoon forms.
🌈 Popular Betta Color Patterns
Some of the most sought-after Bettas aren’t defined by a single color at all.
Instead, they have specific arrangements of multiple colors.
Popular patterns include:
- Koi
- Marble
- Nemo
- Galaxy
- Butterfly
- Mustard Gas
- Grizzle
- Cambodian
- Bicolor
- Multicolor
These names can overlap, and commercial terminology is not always standardized.
🎏 Koi Betta
The Koi Betta is one of the most popular modern varieties.
Koi Bettas generally display irregular patches of colors resembling ornamental koi carp.
Common colors include:
- White
- Red
- Orange
- Black
Many modern Koi Bettas also contain:
- Blue
- Green
- Metallic flecks
Koi is fundamentally a pattern description rather than a tail type.
You can therefore encounter:
- Koi Plakats
- Koi Halfmoons
- Koi Dumbo Bettas
🧩 Marble Betta
Marble Bettas have irregular patches of pigmentation.
The especially fascinating part is that their coloration may change as they age.
A Betta purchased with large white areas may later develop additional dark or colorful patches.
Another may lose or rearrange visible coloration.
This makes marble Bettas particularly unpredictable.
Modern genetic research indicates that mosaic/marble-type coloration has a complex genetic basis rather than being explained by one simplistic “color gene.”
🍬 Candy Betta
“Candy” is a commercial term often applied to multicolored marble-type Bettas with bright irregular patches.
Common combinations include:
- Pink
- Red
- Yellow
- White
- Blue
The exact definition varies considerably between breeders.
🔴 Nemo Betta
Nemo Bettas are usually colorful marble-pattern fish dominated by:
- Red
- Orange
- Yellow
- Black
Many are short-finned Plakats.
There is no completely universal boundary separating “Nemo,” “Candy,” and some “Koi” varieties.
These are hobby and breeder terms rather than separate species.
🌌 Galaxy Betta
A Galaxy Betta usually combines a koi or marble-like base pattern with extensive iridescent or metallic speckling.
The reflective spots can resemble stars scattered across the body.
Galaxy Bettas may contain:
- Blue
- Green
- Red
- Orange
- White
- Black
- Metallic silver
“Galaxy Koi” has become an especially common commercial description.
🦋 Butterfly Betta
Butterfly Bettas display distinctly separated color bands across their fins.
A typical example may have:
- Solid-colored body
- Matching inner fin color
- Contrasting white or clear outer fin edge
The crisp contrast can look especially dramatic on Halfmoon tails.
💙💛 Mustard Gas Betta
Mustard Gas Bettas are generally bicolored fish combining a darker iridescent body with yellow or golden fins.
A typical fish might have:
- Blue or green body
- Yellow fins
- Dark edging
Like many modern Betta names, the term is sometimes applied rather loosely in commercial listings.
🌫️ Grizzle Betta
Grizzle Bettas have irregular flecked or streaked pigmentation over a lighter background.
The appearance can be almost paint-splattered.
Formal Betta competition standards recognize grizzle/marble-type patterned classes.
🐉 Dragon Scale Betta
Dragon Scale Bettas have thick-looking, highly reflective scales that create an armored appearance.
The scales are often:
- White
- Silver
- Metallic
- Pale blue
over a contrasting base color.
A classic Red Dragon, for example, may have:
- Red fins
- Red head
- Thick white or metallic scales across the body
Dragon scaling can occur on many fin forms.
You might therefore see a:
- Dragon Plakat
- Dragon Halfmoon
- Dragon Crowntail
Some heavily scaled lines can develop excessive scaling around the eyes as they mature. This phenomenon is often called diamond eye in the Betta hobby and can interfere with vision.
Not every Dragon Scale Betta develops it, but it is worth knowing about before choosing an extremely heavily scaled fish.
✨ Metallic Betta
Metallic Bettas have increased reflective coloration that produces a shiny, almost metal-like surface.
Colors may include:
- Copper
- Silver
- Green
- Blue
- Gold
Metallic traits have contributed heavily to modern designer Betta varieties.
Genetic research suggests that domestic Betta coloration is more complex than the simple single-gene explanations sometimes repeated in older hobby guides.
👽 What Is an Alien Betta?
The term Alien Betta generally refers to selectively bred hybrid lines with strong wild-Betta ancestry and striking metallic patterns.
They often display:
- Dark bodies
- Blue or green metallic scales
- Defined facial markings
- Short fins
- More wild-type body proportions
Alien Bettas should not simply be treated as another color of ordinary domestic Betta splendens.
The International Betta Congress places hybrids and wild types in distinct show categories.
Their appearance reflects the increasingly complex boundary between ornamental B. splendens and hybrid Betta breeding.
🌿 Wild Betta Species Are Different From Betta Varieties
The genus Betta contains many species besides Betta splendens.
Examples include:
- Betta imbellis
- Betta smaragdina
- Betta mahachaiensis
- Betta siamorientalis
- Betta rubra
- Betta macrostoma
These are different species, not simply colors or tail types of the domestic Siamese Fighting Fish.
Some build bubble nests.
Others are mouthbrooders.
Some can also have substantially different social behavior and water requirements.
A wild Betta species should therefore be researched by its scientific name rather than treated automatically like a pet-store Halfmoon.
🏆 How Betta Shows Classify Fish
Formal Betta exhibitions help illustrate why the word “type” is so complicated.
International Betta Congress classes include categories involving forms such as:
- Halfmoon
- Plakat
- Crowntail
- Doubletail
- Veiltail
- Large pectoral
- Giant
These forms are then further divided according to:
- Sex
- Color
- Pattern
- Finnage
- Breeding status
So two Bettas with the same tail shape may compete in completely different classes because their coloration or pattern differs.
Betta classification is really a system of stacked traits, not a simple list of mutually exclusive breeds.
🐠 Do Different Betta Types Need Different Care?
Their core care requirements are essentially the same.
Most domestic Betta splendens need:
- A heated aquarium
- Gentle filtration
- Clean water
- Access to the surface
- A secure lid
- Appropriate carnivorous food
- Resting areas
- Enough room to explore
A 5-gallon aquarium or larger is an excellent practical minimum for a standard single Betta, and larger tanks are often easier to keep stable.
If you’re replacing an old bowl setup, see The Ultimate Betta Fish Bowl Care Guide for New Owners.
🌊 Long-Finned vs. Short-Finned Betta Care
There is one practical difference worth considering.
Long-Finned Bettas
Halfmoons, Veiltails, and similar fish may:
- Swim more slowly
- Tire more readily in strong current
- Rest frequently
- Be more vulnerable to torn fins
Use gentle water flow and provide broad leaves or resting surfaces near the top of the tank.
Short-Finned Bettas
Plakats generally:
- Swim more powerfully
- Explore more actively
- Handle moderate circulation somewhat better
- Jump surprisingly well
Both types need a secure lid.
🌡️ Do Betta Colors Affect Care?
Usually, no.
A red Betta and a blue Betta do not require different temperatures simply because their pigmentation differs.
However, some specialized traits deserve extra observation.
Examples include:
Dragon Scale: watch for excessive scaling around the eyes.
Very pale or cellophane fish: visual changes associated with health problems may be less obvious.
Marble/Koi: natural color changes can occur and should not automatically be mistaken for illness.
Extreme long-fin forms: watch swimming ability and fin condition.
Choose for health first and color second.
🍽️ Feeding Every Betta Variety
All domestic Betta forms require essentially the same type of diet.
Wild Betta splendens naturally consume foods including zooplankton and insect larvae.
Aquarium foods can include:
- Quality Betta pellets
- Frozen brine shrimp
- Mysis shrimp
- Daphnia
- Appropriate frozen or live insect-based foods
Bettas are primarily carnivorous/insectivorous fish, not algae eaters.
For more detail, see our Betta Fish Pellets guide.
💨 All Betta Types Can Breathe Air
Bettas possess a specialized labyrinth organ that allows them to breathe atmospheric air.
You will regularly see a healthy Betta swim to the surface and take a gulp.
This ability helps wild Bettas survive in shallow, oxygen-variable environments.
It does not mean Bettas prefer:
- Dirty water
- Tiny bowls
- Unfiltered containers
They still benefit greatly from good water quality and appropriate aquarium husbandry.
⚔️ Does Tail Type Affect Aggression?
Not in a simple way.
A Plakat is not automatically more aggressive simply because its fins are short, and a Halfmoon is not guaranteed to be gentle because it has ornamental fins.
Individual temperament varies considerably.
Domestic Bettas have a long breeding history involving selection for both aggression and ornamental appearance.
Male Betta splendens should generally not be housed together because serious fighting can occur.
♀️ What About Female Bettas?
Female Bettas also occur in many of the same:
- Colors
- Patterns
- Scale types
- Tail forms
Their fins are often shorter than those of ornamental males, although modern breeding has produced females with increasingly dramatic finnage.
Females should not automatically be considered peaceful.
They can still be territorial and aggressive toward other Bettas.
So-called Betta sororities require careful planning, substantial space, and close monitoring and are not the easiest choice for beginners.
🧠 How Betta Diversity Became So Extreme
Centuries of human selection transformed the Betta dramatically.
Breeders selected fish for:
- Fighting performance
- Color
- Fin length
- Tail symmetry
- Body size
- Pattern
- Metallic sheen
- Pectoral-fin size
Modern genomic studies have now identified genetic regions associated with several famous Betta traits, including:
- Long fins
- Giant body size
- Dumbo/Elephant Ear fins
- Doubletail
- Blue/green coloration
- Metallic coloration
- Orange pigmentation
- Mosaic patterns
This makes the domestic Betta more than an aquarium curiosity.
It has become a valuable model for scientists studying how selective breeding can reshape animal appearance and behavior.
🔍 How to Choose a Healthy Betta
Color and tail shape should never be your first concern.
Look for a fish with:
- Clear eyes
- Smooth scales
- Good body weight
- Normal swimming
- Strong appetite
- Intact fins
- Normal breathing
- Alert behavior
Avoid choosing a fish solely because it has the longest tail or rarest color if it cannot swim comfortably or shows obvious signs of illness.
A healthy ordinary Veiltail is a far better purchase than an unhealthy exotic designer Betta.
⚠️ Common Betta Variety Myths
“Every Named Betta Is a Different Breed”
Not really.
Many names describe just one visible trait.
“Koi Bettas Are a Different Species”
No.
Most Koi Bettas are ornamental domestic Betta splendens.
“Plakats Are Wild Bettas”
No.
Plakat describes a short-finned domestic form, although its proportions are closer to wild-type Bettas.
“Dragon Scale Is a Tail Type”
No.
Dragon describes scaling and pigmentation.
“Dumbo Is a Tail Type”
Not technically.
The defining feature is the enlarged pectoral fins.
“Every Betta Keeps the Same Color for Life”
Not necessarily.
Marble-pattern Bettas in particular can change dramatically.
“All Bettas Have Huge Fins”
Wild Bettas and Plakats demonstrate that short fins are entirely normal.
🌟 Which Betta Type Is Best for Beginners?
For a beginner, I would prioritize health and swimming ability rather than buying the most elaborate fish available.
Excellent choices include:
- Veiltail Betta
- Standard Plakat
- Halfmoon Plakat
- Healthy Delta
- Moderate-finned Halfmoon
A short-finned Plakat can be particularly appealing because it avoids some of the practical issues associated with extremely large ornamental fins.
That said, a healthy Veiltail or Halfmoon can also thrive with proper care.
The aquarium setup matters more than the designer label.
💎 What Is the Rarest Betta Type?
There is no single permanent answer.
Betta trends change constantly as breeders develop new combinations of:
- Colors
- Patterns
- Metallic traits
- Scale types
- Fin forms
A variety considered rare today may become common once breeders establish a successful line.
Truly unusual Bettas may involve complex combinations of several desirable traits rather than one simple color.
For more specialized varieties, see our Rare Betta Fish: A Collector’s Guide to Exotic Beauties.
❤️ Which Betta Type Is the Most Beautiful?
That’s entirely subjective—and that’s part of the fun.
Some aquarists love the enormous symmetry of a Halfmoon.
Others prefer the athletic appearance of a Plakat.
A Crowntail offers dramatic spikes, while a Koi Betta may look like a tiny swimming abstract painting.
The most impressive fish may be:
- A simple solid red Veiltail
- A brilliant blue Halfmoon
- A Black Dragon Plakat
- A multicolored Galaxy Koi
- A white Dumbo
- A wild-type Betta with understated iridescence
There is no single “best” Betta variety.
There are simply different expressions of an extraordinarily diverse fish.
🌈 Final Thoughts
The world of Betta varieties is much easier to understand once you stop treating every name as a separate breed.
Domestic Betta splendens can be described through several overlapping characteristics:
Tail type tells you about fin shape.
Color describes the fish’s primary pigmentation.
Pattern explains how those colors are arranged.
Scale traits describe characteristics such as Dragon or metallic appearance.
Special forms include traits such as Dumbo pectoral fins and Giant body size.
Those features can then be combined in almost endless ways.
That is how one species can produce fish as different-looking as a solid red Veiltail, a Black Dragon Plakat, a white Dumbo Halfmoon, and a multicolored Galaxy Koi.
But beneath all those colors and fins is still a Betta.
Whichever variety catches your eye, choose a healthy fish and provide it with a heated, filtered aquarium, clean water, appropriate food, gentle places to rest, and enough room to explore.
The best Betta isn’t necessarily the rarest or most expensive.
It’s the one whose beauty can be enjoyed while its health and natural behavior come first.
