White betta fish are among the most elegant forms of Betta splendens. Some are snowy and opaque, others shimmer like polished silver, and still others appear almost translucent until the light catches their scales.
But “white betta” is not one single genetic variety.
The term can describe several different appearances, including opaque white, platinum, cellophane, marble, metallic, and other selectively bred forms. Some remain almost completely white throughout their lives, while others unexpectedly develop patches of blue, red, black, or other colors as they mature.
That makes white bettas especially interesting for anyone fascinated by fish coloration and genetics.
Fortunately, their basic care is no different from other domestic bettas. A white betta still needs warm, clean water, appropriate filtration, enough swimming space, a high-quality diet, and an enriched aquarium.
Here’s how to identify the different types of white betta fish, understand their coloration, care for them properly, and make sense of their surprisingly complicated genetics.

🤍 What Is a White Betta Fish?
A white betta is a domestic Betta splendens selectively bred to display very little obvious red, yellow, blue, or black coloration—or to produce reflective cells that make the fish appear white, silver-white, or pearlescent.
Wild bettas don’t normally look like the elaborate white fish seen in the aquarium trade.
Modern domestic bettas are the result of generations of selective breeding for:
- Color
- Pattern
- Fin length
- Tail shape
- Body size
- Metallic appearance
- Other ornamental characteristics
White is only one expression of that enormous domesticated diversity.
White bettas may also have almost any common tail type, including:
- Veiltail
- Halfmoon
- Plakat
- Crowntail
- Delta
- Double tail
Color and fin shape are separate characteristics, so there is no single “white betta tail.”
🎨 Types of White Betta Fish
Not every white betta looks the same.
Breeder and retailer terminology also varies, so two sellers may use slightly different names for visually similar fish.
These are some of the most common white or near-white forms you may encounter.
⚪ Opaque White Betta
The opaque white betta is what many people imagine when they hear “white betta.”
These fish often have a:
- Milky appearance
- Chalky white body
- White fins
- Dense rather than transparent coloration
A high-quality opaque white betta may appear almost snow-white from head to tail.
Some individuals have faint iridescence when viewed under bright aquarium lighting.
Opaque coloration is the product of selective breeding involving several aspects of pigment and reflective coloration rather than simply turning all pigmentation “off.”
✨ Platinum White Betta
Platinum bettas usually have a brighter, more reflective appearance.
Instead of the soft white of an opaque betta, platinum fish may look:
- Silvery
- Pearlescent
- Metallic
- Brilliant white
- Reflective under aquarium lighting
The effect is produced largely by structural and reflective coloration rather than a white pigment comparable to paint.
Depending on the breeding line, a fish sold as “platinum white” may also overlap visually with metallic or dragon-type bettas.
Because ornamental betta names are not governed by one universal scientific naming system, expect some variation between breeders.
👻 Cellophane Betta
A cellophane betta may look white at first glance, but it is quite different from an opaque white fish.
Cellophane bettas have relatively little visible pigment.
Their bodies and fins can appear:
- Translucent
- Pale
- Flesh-colored
- Clear
- Slightly pinkish
The pink or peach tint often comes from underlying tissues and blood vessels showing through rather than from a strong pink pigment layer.
A cellophane fish therefore tends to look more transparent than a true opaque white betta.
🪩 Metallic White Betta
Metallic bettas contain highly reflective coloration that can create a white, silver, or pearlescent appearance.
Depending on the fish and lighting, metallic white bettas may show subtle tones of:
- Silver
- Blue
- Green
- Lavender
- Gold
The color can appear different when the fish changes angle.
That is one reason photographing white and metallic bettas can be surprisingly difficult—the same fish may look pure white in one picture and pale blue in another.
🐉 White Dragon-Scale Betta
Some white or platinum bettas are marketed as dragon-scale bettas.
Dragon-scale fish have unusually thick-looking, reflective scales that can produce an armor-like appearance.
A white dragon-type betta may therefore look almost metallic or covered in tiny porcelain tiles.
Dragon coloration can also occur alongside:
- Red
- Blue
- Black
- Copper
- Multicolor patterns
“Dragon” refers primarily to the appearance of the scales rather than one specific body color.
🎭 White Marble Betta
White often appears as part of a marble or mosaic pattern.
A white marble betta might have a white base with patches of:
- Black
- Blue
- Red
- Orange
- Yellow
- Green
- Metallic colors
And those patches may not stay the same throughout the fish’s life.
Mosaic coloration is one of the most unpredictable aspects of domestic betta breeding.
Modern genomic research found multiple genetic regions associated with mosaic coloration, suggesting that the pattern has a complex, polygenic basis.
So while marble bettas are often described in the hobby as having a simple “jumping gene,” the actual molecular genetics have not been fully resolved.
🌈 Can a White Betta Change Color?
Yes.
Some white bettas remain relatively consistent throughout their lives.
Others can change dramatically.
A fish that appears nearly pure white when purchased might eventually develop:
- Black spots
- Blue patches
- Red areas
- Metallic scales
- Mixed-color patterns
This is particularly common when marble or mosaic genetics are present in the fish’s ancestry.
Color development can continue as a juvenile matures into an adult, and mosaic-pattern bettas may continue changing later in life.
That doesn’t necessarily mean anything is wrong.
You may simply own a genetically unpredictable fish.
🧬 Understanding White Betta Genetics
Betta coloration is far more complicated than:
One gene = one color.
Fish coloration is created by specialized pigment and reflective cells called chromatophores.
Different chromatophore types contribute different visual effects.
These include cells involved in:
- Dark pigmentation
- Red pigmentation
- Yellow pigmentation
- Reflective or iridescent coloration
The colors we see are produced by how those cells are distributed, how strongly pigment pathways are expressed, and how different layers interact.
Scientific studies comparing red, blue, black, yellow, white, Cambodian, and marble bettas have identified numerous pigmentation-related genes with different expression patterns among color varieties.
In other words:
There isn’t one universal “white betta gene” that explains every white fish sold in the hobby.
Different white appearances can arise through different combinations of reduced pigmentation and reflective coloration.
🔬 What Science Has Learned About Betta Color
Betta genetics has become a surprisingly active area of research.
Genome and transcriptome studies have investigated genes associated with:
- Melanin production
- Red and yellow coloration
- Iridescence
- Mosaic patterns
- Fin morphology
- Eye color
- Albinism
A 2022 transcriptome study specifically included a white Betta splendens variety alongside red, blue, black, yellow, Cambodian, and marble fish.
Researchers identified thousands of differences in gene expression across the color comparisons, including pigmentation-related genes.
More recent work has continued comparing pigmentation pathways between white, red, blue, and multicolored bettas.
The takeaway for aquarium keepers is simple:
Betta color genetics is considerably more complicated than many old breeding charts suggest.
👁️ Are White Bettas Albino?
Usually not.
A normal white betta and an albino betta are different.
A white opaque or platinum betta can still have normally pigmented eyes and functioning pigment pathways even though its body looks white.
True albinism involves disruption of melanin pigmentation.
Research into Betta splendens has identified an albinotic phenotype associated with a major genetic locus involving regulation of mitfa, an important pigmentation gene.
Albino bettas may display:
- Very pale bodies
- Reduced dark pigment
- Pinkish or reddish-looking eyes
True albino bettas are much less commonly encountered than ordinary opaque white or platinum fish.
So:
White ≠ albino.
A snowy white betta with dark eyes is not automatically an albino.
👀 Why Does My White Betta Have Black Eyes?
Because most white bettas are not albino.
Dark eyes are perfectly normal in opaque, platinum, cellophane, marble, and other white-bodied bettas.
Body coloration and eye pigmentation do not necessarily follow the same pattern.
Research into domestic bettas has identified considerable eye-color diversity as well as complex body-color genetics.
🌸 Why Does My White Betta Look Pink?
A white betta may appear pink for several reasons.
Translucent Tissue
Cellophane or lightly pigmented fish can show the color of blood vessels and tissues beneath the skin.
Lighting
Warm-colored aquarium LEDs can turn white fish cream, pink, or peach visually.
Fin Transparency
Thin translucent fins may allow underlying tissue coloration to show through.
Natural Color Development
A young white fish may eventually develop red or pink pigmentation.
If the fish is active, eating, and otherwise healthy, a mild pink tint is not automatically a sign of disease.
🔵 Why Is My White Betta Turning Blue?
Genetics are a likely explanation if the change occurs gradually and the fish otherwise appears healthy.
Many domestic betta lines contain complicated color ancestry.
A white or marble fish can begin developing iridescent:
- Blue
- Turquoise
- Green
- Steel-colored
areas as it matures.
Lighting can also make reflective white scales appear blue from certain angles.
A gradual color change in a healthy betta is very different from a sick fish becoming suddenly pale.
⚫ Why Is My White Betta Developing Black Spots?
Again, marble or mosaic-type coloration may be responsible.
Black pigment can appear in areas that were previously white.
The pattern may:
- Expand
- Shrink
- Break into spots
- Merge into patches
- Continue changing over time
A new dark patch that is simply pigmented and flat may be normal coloration.
However, an actual:
- Lump
- Ulcer
- Raised lesion
- Injured area
should be evaluated as a health issue rather than assumed to be genetics.
🚨 White Color vs. Loss of Color From Illness
This distinction matters.
A genetically white betta has naturally pale coloration.
A normally red or blue betta that suddenly becomes very pale may be experiencing:
- Stress
- Poor water quality
- Temperature problems
- Disease
- Injury
Color loss must always be interpreted relative to what is normal for that individual fish.
With a naturally white betta, health is often easier to assess using other signs.
Look at:
- Appetite
- Activity
- Breathing
- Fin position
- Body condition
- Swimming ability
- Scales
- Eyes
Behavior is often more informative than color alone.
🏠 White Betta Fish Tank Size
White bettas don’t need smaller or larger aquariums than other bettas.
The Aquarista recommends:
At least 5 gallons for one adult betta
A 10-gallon aquarium is an excellent choice when space permits.
A properly sized aquarium gives your fish room for:
- Swimming
- Exploring
- Resting
- Plants
- Hiding places
It also provides greater water stability than a tiny bowl.
Read Betta Fish Tank Size: Minimum Tank Size, Setup & Space Requirements for our complete setup guide.
🌡️ White Betta Fish Temperature
White coloration does not change the betta’s tropical temperature requirements.
Maintain the aquarium around:
76–81°F
with approximately 78–80°F being an excellent target for many adult bettas.
Use:
- An aquarium heater
- A separate thermometer
unless your aquarium naturally remains within the appropriate temperature range around the clock.
Temperature stability matters more than constantly trying to hit one exact degree.
See Betta Fish Heater Guide: Best Temperature, Heater Size & Setup Tips.
💧 White Betta Fish Water Parameters
Aim for clean, stable freshwater conditions.
| Parameter | Target |
|---|---|
| Temperature | 76–81°F |
| pH | Roughly 6.5–7.8 |
| Ammonia | 0 ppm |
| Nitrite | 0 ppm |
| Nitrate | Kept low through regular maintenance |
| Water movement | Gentle |
The aquarium should also be fully cycled or carefully managed while biological filtration becomes established.
Read Betta Fish pH: Ideal Range, Water Parameters & How to Adjust It for more information about pH, KH, GH, and water stability.
💦 Do White Bettas Need a Filter?
Yes, gentle filtration is strongly recommended.
A filter:
- Supports biological filtration
- Captures debris
- Helps circulate water
- Makes stable aquarium conditions easier to maintain
But avoid excessive current.
Long-finned bettas can become exhausted when constantly battling strong flow.
Useful options include:
- Sponge filters
- Adjustable internal filters
- Low-flow filters
- Baffled hang-on-back filters
Your betta should be able to swim normally throughout the aquarium without being pushed around.
🌿 Best Aquarium Setup for a White Betta
A natural-looking planted aquarium can make a white betta especially striking.
Consider adding:
- Anubias
- Java fern
- Cryptocoryne
- Java moss
- Water sprite
- Floating plants
- Smooth driftwood
- Aquarium-safe caves
Provide both:
cover + open swimming space
Bettas frequently investigate their surroundings and appreciate places to hide and rest.
🌑 What Background Looks Best With a White Betta?
This is largely an aesthetic choice, but white fish can look spectacular against darker surroundings.
Popular options include:
- Black backgrounds
- Dark gravel
- Natural brown driftwood
- Green plants
- Dark planted substrates
The contrast can make a white or platinum betta visually pop.
A lighter aquarium isn’t harmful, however.
Choose your tank design based on safe husbandry first and appearance second.
💡 Does Lighting Affect White Betta Color?
Absolutely.
A white fish may look very different under:
- Warm white LEDs
- Cool white LEDs
- Blue-heavy lights
- Natural daylight
Platinum and metallic bettas are particularly responsive to lighting because much of their appearance comes from reflective structural coloration.
Under one light, your fish might look snowy white.
Under another, it might appear:
- Silver
- Lavender
- Pale blue
- Cream
- Pinkish
That doesn’t necessarily mean the fish changed color genetically overnight.
The light may simply be changing what you see.
🍽️ What Do White Betta Fish Eat?
White bettas have the same dietary needs as other domestic bettas.
Bettas are carnivorous fish and need a protein-rich diet.
A high-quality betta pellet can serve as the staple food.
Variety can include appropriately sized:
- Brine shrimp
- Daphnia
- Bloodworms
- Other safe frozen or live foods
Avoid overfeeding.
A betta doesn’t need extra food to make its white color brighter.
Excess food primarily creates:
- Waste
- Water-quality problems
- Potential digestive issues
See our Betta Fish Pellets guide for more feeding guidance.
🦐 Can Food Make a White Betta Change Color?
Diet can influence the appearance of certain fish pigments, but feeding color-enhancing foods will not reliably transform a genetically white betta into a completely different variety.
Genetics establish much of the fish’s potential coloration.
Good nutrition can help maintain:
- Healthy skin
- Normal scales
- Fin growth
- Overall body condition
But no food can guarantee that a marble betta remains white.
If the fish carries genetics for changing pigmentation, a special diet won’t permanently switch those genes off.
🐠 White Betta Fish Tank Mates
A white betta’s temperament is determined by the individual fish—not its color.
One white betta may tolerate tank mates.
Another may attack anything that moves.
Male bettas should not be housed together.
Possible tank mates in sufficiently large aquariums may include certain:
- Snails
- Shrimp
- Small peaceful schooling fish
- Bottom-dwelling species
But compatibility depends on:
- Tank size
- Species
- Group requirements
- Water parameters
- Individual betta temperament
A 5-gallon aquarium should generally remain a one-betta-focused setup rather than being packed with additional fish.
⚔️ Are White Bettas More Aggressive?
There is no good evidence that being white automatically makes a betta more aggressive.
Aggression in Betta splendens is influenced by complicated genetic, hormonal, environmental, and individual factors.
Color alone is not a reliable personality test.
A peaceful-looking white Halfmoon can be highly territorial.
A dark plakat can be relatively calm.
Treat every betta as an individual.
🫧 Do White Male Bettas Build Bubble Nests?
Yes.
Healthy adult males may build bubble nests regardless of whether they are:
- White
- Blue
- Red
- Black
- Koi
- Marble
- Multicolored
Bubble-nest building is reproductive behavior, not a color-specific trait.
However, the presence or absence of a bubble nest is not a perfect measure of health or happiness.
Some males build enormous nests.
Others rarely do.
♀️ Can Female Bettas Be White?
Absolutely.
White coloration occurs in both males and females.
Females are sometimes overlooked because the ornamental trade traditionally emphasized long-finned males, but female bettas are available in an enormous range of colors.
White females may display:
- Opaque coloration
- Platinum coloration
- Marble patterns
- Metallic scales
- Shorter fins
Sex and color are separate traits.
🧬 Can You Breed Two White Bettas?
Yes—but don’t assume that two white parents will automatically produce a tank full of identical white offspring.
Domestic betta genetics can be complicated.
The parents may carry hidden genetic variation inherited from:
- Red lines
- Blue lines
- Metallic lines
- Marble lines
- Dark-bodied ancestors
- Other crosses
Depending on their ancestry, the offspring may develop several colors and patterns.
Research into betta coloration demonstrates that numerous pigmentation-related genes contribute to phenotype.
Unless you know the breeding history of both fish, predicting the exact outcome can be difficult.
🥚 Is Breeding White Bettas Easy?
The reproductive process is essentially the same as breeding other Betta splendens, but breeding should not be attempted casually.
One pair may produce hundreds of eggs.
Raising the fry requires:
- Separate breeding setup
- Warm stable water
- Appropriate filtration
- Microscopic first foods
- Brine shrimp or other fry foods
- Grow-out space
- Frequent maintenance
- Eventually separating aggressive young males
If you’re considering breeding, read Betta Fish Eggs: Hatching, Care, Development & Breeding Guide.
🧬 Will White Betta Babies Stay White?
Not necessarily.
Juvenile betta pigmentation develops as the fish grows.
Scientific research following developing bettas has documented considerable variation in pigmentation both between breeding events and among offspring from the same breeding.
Adult coloration can become even more diverse during juvenile development.
This means a pale fry might later become:
- White
- Blue
- Red
- Black
- Marble
- Multicolored
depending on its genetics.
Producing stable color lines requires careful selective breeding over generations.
🔄 Why Did My White Betta Change Completely?
A dramatic transformation can happen with marble or mosaic bettas.
For example:
Month 1: Mostly white with one blue spot
Month 3: White and blue patches
Month 6: Mostly blue with a white head
Month 12: Blue, black, and white marble
The fish hasn’t changed species.
Its pigmentation pattern has changed.
This unpredictability is part of what makes marble-type bettas fascinating.
If you absolutely want a fish that remains visually consistent, purchase from an experienced breeder who has worked with a stable line—but even then, biology offers no absolute guarantee.
🤒 Can Illness Change a White Betta’s Appearance?
Yes.
Although white fish don’t show traditional “paleness” as clearly as brightly colored bettas, illness can still alter their appearance.
Look for:
- Red or irritated areas
- Raised scales
- White fuzzy material
- Salt-like dots
- Open sores
- Darkened areas
- Swelling
- Damaged fins
- Cloudy eyes
Behavioral changes are also important.
Watch for:
- Refusing food
- Lethargy
- Clamped fins
- Rapid breathing
- Abnormal swimming
- Persistent bottom-sitting
Whenever something changes suddenly, test the water first.
⚪ Can a White Betta Get Ich?
Yes.
White coloration provides no protection against parasites.
Ich is caused by Ichthyophthirius multifiliis and typically produces tiny salt-grain-like spots.
Unfortunately, ich can sometimes be harder to notice against a naturally white fish.
Watch for accompanying symptoms such as:
- Flashing
- Clamped fins
- Rapid breathing
- Gill irritation
- Lethargy
Our Betta Fish Ich: Symptoms, Treatment & Prevention Guide explains how to distinguish ich from other white lesions and how the parasite’s life cycle affects treatment.
🎈 Watch for Bloating
A swollen abdomen may stand out clearly on a light-colored betta.
Possible explanations include:
- Overfeeding
- Digestive problems
- Developing eggs in females
- Infection
- Fluid accumulation
- Parasites
- Internal disease
- A mass
Bloating is a symptom, not one specific diagnosis.
See Is Your Betta Fish Bloated? Here’s What You Need to Know before attempting treatment.
⏳ How Long Do White Betta Fish Live?
White bettas have the same general lifespan as other domestic Betta splendens.
With good care, a typical lifespan is approximately:
3–5 years
Individual fish may live shorter or longer lives.
Longevity is influenced by:
- Genetics
- Age when purchased
- Water quality
- Temperature
- Nutrition
- Disease
- Stress
- Overall husbandry
Color itself does not automatically give a betta a longer or shorter lifespan.
See Betta Fish Lifespan: How Long They Live & How to Help Them Live Longer.
🛒 How to Choose a Healthy White Betta
When shopping for a white betta, look beyond color.
Choose a fish that appears:
- Alert
- Responsive
- Interested in its surroundings
- Able to swim normally
- Free of severe swelling
- Free of obvious ulcers
- Free of heavy parasite infestations
Look closely at the fins.
They should match the expected tail type and not show progressive deterioration.
Also examine the fish from above.
The scales should normally lie flat rather than projecting outward in a pinecone pattern.
💵 Are White Betta Fish Expensive?
Prices vary enormously.
A common white betta from a large retailer may be relatively inexpensive.
A breeder-produced fish with exceptional:
- Opaque coverage
- Platinum coloration
- Tail symmetry
- Metallic scaling
- Pedigree
may command a much higher price.
The purchase price of the fish is only a small part of ownership.
You still need an appropriate aquarium, heater, filter, test kit, conditioner, food, and furnishings.
See The True Cost of Owning a Betta Fish: A Complete Guide.
💎 Are White Bettas Rare?
Some white bettas are relatively uncommon compared with standard red and blue fish, but “white” by itself does not automatically mean rare.
Availability depends on:
- Region
- Retailer
- Breeder
- Tail type
- Specific genetic line
- Pattern quality
- Demand
A basic white fish may be readily available.
A near-perfect opaque white show-quality Halfmoon from a carefully maintained breeding line may be much harder to find.
If you’re interested in unusual forms, see Rare Betta Fish: Types, Colors, Varieties & Collector Guide.
❓ Frequently Asked Questions About White Betta Fish
Are white betta fish natural?
Domestic white bettas are selectively bred ornamental forms of Betta splendens. Wild bettas generally do not display the intense opaque white or platinum coloration seen in modern aquarium strains.
Are white betta fish albino?
Usually not. Opaque, platinum, metallic, and cellophane white bettas are not automatically albino. True albinism involves disruption of melanin pigmentation and may produce reddish or pink-looking eyes.
Do white betta fish change color?
Some do. White fish carrying mosaic or marble-type coloration may develop new patches of blue, black, red, or other colors as they grow.
Why is my white betta turning blue?
Iridescent coloration may become more visible with age, genetics may produce new pigmentation, or aquarium lighting may reveal blue structural colors that were always present.
Why is my white betta turning black?
If the dark areas are flat, pigmented, and the fish is healthy, marble or mosaic coloration may be responsible. Raised, damaged, or ulcerated areas require a health evaluation.
Why is my white betta turning pink?
Thin or translucent tissues can reveal underlying blood vessels, particularly in cellophane-type fish. Lighting and natural pigmentation can also create a pink tint.
Will my white betta stay white forever?
There is no guarantee. Stable white lines may remain quite consistent, while fish with marble or mosaic ancestry may change dramatically.
What is the difference between opaque and platinum bettas?
Opaque whites generally have a dense, milky or chalk-like white appearance. Platinum fish usually have a brighter reflective or metallic white appearance. Breeder terminology varies.
What is the difference between a white betta and a cellophane betta?
A white opaque betta has dense visible coloration. A cellophane betta has very little pigment and tends to appear transparent or flesh-colored.
Are white bettas harder to care for?
No. Their basic husbandry requirements are the same as those of other domestic Betta splendens.
What size tank does a white betta need?
We recommend at least 5 gallons for one adult betta, with 10 gallons an excellent option.
Do white bettas need heaters?
Usually, yes. Maintain a stable tropical temperature around 76–81°F.
Do white bettas need filters?
Gentle filtration is strongly recommended.
What do white bettas eat?
Feed an appropriate carnivorous betta diet, usually based around a quality high-protein pellet with suitable frozen or live foods for variety.
Can white bettas live with other fish?
Potentially, in an appropriately sized aquarium with carefully selected tank mates. Compatibility depends on the individual betta and the needs of the other species.
Can two white male bettas live together?
No. Their matching color does not make them compatible. Male bettas are highly territorial toward other males.
Are female white bettas available?
Yes. White, platinum, opaque, marble, and other pale colorations can occur in females as well as males.
Can two white bettas produce colored babies?
Yes. Domestic betta color genetics are complex, and apparently white parents can carry genetic variation that produces colored or patterned offspring.
How long do white bettas live?
Approximately 3–5 years is a realistic general expectation with proper care, although individual lifespan varies.
Does a black background make a white betta happier?
Not necessarily, but dark backgrounds and green plants provide striking visual contrast. Choose tank furnishings primarily for safety, cover, and enrichment.
❤️ White Bettas Are More Than a Color
A beautiful white betta may look simple at first glance.
Genetically, it can be anything but simple.
White coloration can involve complex interactions among pigment cells, reflective structures, and numerous genes. A snowy opaque fish, shimmering platinum betta, nearly transparent cellophane, and white marble can therefore look similar from across the room while representing very different pigmentation patterns.
Modern genetic research has also shown just how much remains to be learned about domestic betta coloration.
For the aquarium keeper, however, care remains straightforward.
Give your white betta:
- At least 5 gallons of space
- Warm water around 76–81°F
- Gentle filtration
- Zero ammonia and nitrite
- Stable water chemistry
- A high-quality diet
- Plants and hiding places
- Open swimming areas
- Easy surface access
And don’t be surprised if the fish you bring home doesn’t look exactly the same a year later.
For some white bettas, changing color isn’t a flaw.
It’s part of what makes the genetics of Betta splendens so fascinating.
