Crowntail Betta Care Guide: Complete Species Profile 2025

If you've ever been captivated by a fish that looks like it's wearing an elaborate royal crown, you've likely encountered the magnificent crowntail betta. I've kept bettas for over a decade, and the crowntail variety consistently stops people in their tracks with its dramatic, spiky finnage that resembles delicate lace or intricate webbing.

The crowntail betta (Betta splendens) stands out among the types of betta fish with its reduced webbing between fin rays, creating that distinctive crown-like appearance. While these fish share the same care requirements as other bettas, their unique finnage demands some special considerations that I'll cover in detail throughout this guide.

What truly sets crowntails apart isn't just their appearance—it's their personality. These fish exhibit remarkable intelligence and can recognize their owners, learn feeding schedules, and even perform simple tricks. I've watched countless crowntails develop unique personalities, from bold explorers who investigate every corner of their tank to more reserved individuals who prefer watching the world from their favorite hiding spot.

This comprehensive guide draws from scientific research, veterinary recommendations, and years of hands-on experience to provide you with everything needed for successful crowntail betta care. Whether you're considering your first betta or looking to expand your knowledge, I'll walk you through every aspect of keeping these remarkable fish healthy and thriving.

Species Overview and Origins

The crowntail betta represents a selectively bred variant of Betta splendens, originally developed in Indonesia during the late 1990s. Indonesian breeder Achmad Yusuf is credited with creating this distinctive variety through careful selective breeding, focusing on reducing the webbing between fin rays to achieve that characteristic crown appearance.

Unlike wild bettas found in Thailand, Cambodia, and Vietnam's rice paddies and shallow waters, crowntails exist purely as a domesticated variety. Their wild ancestors inhabit slow-moving streams, marshes, and flooded fields where dissolved oxygen levels fluctuate dramatically. This evolutionary background explains why all bettas, including crowntails, possess a labyrinth organ allowing them to breathe atmospheric air—a crucial adaptation that influences their care requirements.

According to research published in the National Center for Biotechnology Information, domesticated bettas like crowntails have been bred for specific traits over hundreds of generations, resulting in fish that differ significantly from their wild counterparts in both appearance and behavior. While wild bettas display relatively short fins and muted colors, crowntails showcase elaborate finnage that can extend up to three times their body length.

Scientific Classification

Understanding the crowntail's taxonomic classification helps explain its care needs:

Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii
Order: Anabantiformes
Family: Osphronemidae
Genus: Betta
Species: B. splendens
Variety: Crowntail

Physical Characteristics and Identification

The crowntail's most defining feature—reduced webbing between fin rays—creates extensions that resemble spikes or a crown. This webbing reduction should exceed 33% of the fin ray length to qualify as a true crowntail, though show-quality specimens often display 50% or greater reduction. The fin rays themselves appear rigid and pointed, creating a dramatic silhouette when the fish flares.

Male crowntails typically reach 2.5 to 3 inches in body length, with fins extending significantly beyond. Females remain smaller at approximately 2 to 2.5 inches with proportionally shorter fins. I've noticed that well-cared-for males can develop finnage spanning up to 8 inches in total spread when fully flared—an impressive display that never fails to amaze visitors.

Color Variations

Crowntails exhibit an astounding array of colors and patterns. During my years working with these fish, I've encountered:

Solid colors: Red, blue, turquoise, yellow, orange, black, white, and purple
Bi-colors: Two distinct colors with clear separation
Multicolors: Three or more colors creating complex patterns
Marble: Irregular blotches and patterns that can change over time
Dragon scale: Metallic scales creating an armored appearance
Butterfly: Distinct banding patterns on fins
Koi patterns: Red, white, and black combinations resembling koi carp

The iridescent layer present in many crowntails creates a metallic sheen that shifts depending on lighting angles. This iridescence can appear as copper, gold, or steel blue overlays on the base color.

Gender Differences

Distinguishing between male and female crowntails becomes straightforward once you know what to look for. Males display longer, more elaborate fins with pronounced crown-like extensions. Their bodies appear more streamlined, and they exhibit more vibrant coloration. Males also possess a visible beard (gill membrane) that becomes prominent when flaring.

Females feature shorter fins with less dramatic crowning, though quality breeding has produced females with increasingly impressive finnage. They display a rounder body shape, particularly when carrying eggs, and a visible white egg spot (ovipositor) located behind the ventral fins. Female coloration, while sometimes less intense than males, can still be quite striking in well-bred specimens.

Tank Setup and Habitat Requirements

Creating an optimal environment for your crowntail betta requires careful attention to tank parameters, equipment selection, and aquascaping. Recent research from ScienceDirect's Aquacultural Engineering journal indicates that tank shape and size significantly impact betta welfare and growth rates.

Tank Size and Dimensions

While bettas can survive in small containers, thriving requires adequate space. I recommend a minimum of 5 gallons for a single crowntail, though 10 gallons provides better water stability and swimming room. The extra finnage of crowntails makes them less agile swimmers than short-finned varieties, so horizontal swimming space takes priority over height.

Ideal tank dimensions provide at least 24 inches of horizontal length. Shallow, long tanks work exceptionally well, allowing easy surface access for breathing while providing exploration space. I've found that my crowntails in 10-gallon long tanks (24" x 12" x 12") display more active behavior and vibrant colors compared to those in standard 5-gallon setups.

Water Parameters

Maintaining stable water conditions prevents stress and disease. Based on veterinary recommendations and scientific research, crowntails thrive in these parameters:

Temperature: 76-82°F (24-28°C), with 78-80°F being optimal
pH: 6.5-7.5, slightly acidic to neutral preferred
Ammonia: 0 ppm (toxic at any detectable level)
Nitrite: 0 ppm (toxic at any detectable level)
Nitrate: Below 20 ppm, ideally under 10 ppm
General Hardness (GH): 4-8 dGH
Carbonate Hardness (KH): 3-5 dKH

Temperature stability proves crucial—fluctuations exceeding 2°F within 24 hours can trigger stress and immune suppression. I use adjustable heaters with built-in thermostats and always keep a backup heater on hand. Digital thermometers provide more accurate readings than stick-on strips.

Filtration and Water Flow

Crowntails require gentle filtration due to their elaborate fins. Strong currents exhaust these fish and can damage delicate fin tissue. Sponge filters work excellently, providing biological filtration without creating excessive flow. If using a hang-on-back or canister filter, baffle the output using a pre-filter sponge or direct flow against the tank wall.

I've successfully used adjustable flow filters set to their lowest setting, combined with floating plants to further reduce surface agitation. The goal is creating enough circulation to prevent dead spots while allowing your crowntail to swim comfortably without fighting current.

Substrate and Decorations

Substrate choice impacts both aesthetics and maintenance. Fine sand or smooth gravel works well, avoiding sharp edges that could tear fins. I prefer dark substrates that enhance color visibility and create a natural appearance. Bare-bottom tanks simplify cleaning but lack the biological benefits of substrate.

When selecting decorations, prioritize smooth surfaces. Live plants provide excellent enrichment—Java fern, Anubias, and Amazon sword plants prove particularly suitable. These hardy species tolerate the warm water bettas require while providing resting spots near the surface. Floating plants like Amazon frogbit or dwarf water lettuce create shaded areas and help crowntails feel secure.

Avoid plastic plants with sharp edges, rough decorations, and anything with small openings where fins could snag. I run a pantyhose test on all decorations—if the material snags pantyhose, it can damage crowntail fins.

Diet and Feeding Requirements

Proper nutrition forms the foundation of crowntail health, influencing everything from color vibrancy to disease resistance. As carnivorous fish, bettas require protein-rich diets mimicking their natural prey of insects, larvae, and small crustaceans.

Staple Diet Components

Quality betta pellets should form the dietary foundation. Look for formulations with whole fish or fish meal as the first ingredient, containing at least 40% crude protein. I feed my crowntails 3-4 pellets twice daily, adjusting based on individual metabolism and activity level. The best betta fish food options include brands specifically formulated for bettas' nutritional needs.

Pellet size matters—crowntails have small mouths and can struggle with large pellets. I prefer 1-1.5mm pellets that fish can easily consume. Soaking pellets for 30 seconds before feeding prevents digestive issues from expanding food.

Supplemental Foods

Variety enhances nutrition and provides enrichment. I supplement pellets with:

Frozen bloodworms: High protein treat, feed 2-3 times weekly
Frozen brine shrimp: Excellent for conditioning, rich in carotenoids
Frozen daphnia: Natural laxative properties, helps prevent bloating
Freeze-dried foods: Convenient but requires pre-soaking to prevent constipation
Live foods: Mosquito larvae, wingless fruit flies, or cultured foods provide excellent enrichment

I maintain a feeding schedule rotating between different foods throughout the week. Monday and Thursday might be pellet-only days, Tuesday and Friday include frozen bloodworms, Wednesday features brine shrimp, and weekends involve live or freeze-dried treats. This variety ensures complete nutrition while keeping feeding time interesting.

Feeding Frequency and Portion Control

Overfeeding remains the most common dietary mistake with bettas. Their stomach approximately equals their eye size—a useful visual reference for portion control. I feed adult crowntails twice daily, offering only what they consume within 2-3 minutes.

Young crowntails under six months benefit from three smaller daily feedings supporting rapid growth. Senior fish over three years may require reduced portions or once-daily feeding as metabolism slows.

Implementing a weekly fasting day helps prevent digestive issues and obesity. I skip feeding every Sunday, allowing the digestive system to clear completely. This practice mimics natural feeding patterns where wild bettas don't find food daily.

Behavior and Temperament

Understanding crowntail behavior enables better care and early problem detection. These intelligent fish display complex behaviors ranging from territorial displays to playful interactions with their environment.

Typical Behavior Patterns

Healthy crowntails exhibit active exploration, investigating their territory regularly. They often establish favorite spots—perhaps a broad leaf near the surface for resting or a cave for security. I've observed my crowntails developing daily routines, becoming more active during specific hours and anticipating feeding times.

Flaring represents normal territorial behavior where males expand their gill covers and spread fins to appear larger. Brief flaring sessions provide exercise and mental stimulation. I use a small mirror for 5-minute sessions twice weekly, allowing controlled flaring without stress from constant visual contact with other fish.

Bubble nest construction indicates sexual maturity and good health in males. These foam structures at the water surface serve as nurseries in breeding situations. Even without females present, content males often build elaborate nests. I view regular nest building as a positive welfare indicator.

Aggression and Territoriality

The "fighting fish" reputation stems from intense male territoriality. Males cannot cohabit—they will fight to exhaustion or death. This aggression extends to similar-looking fish, including other Anabantoids or fish with flowing fins.

Research from BMC Zoology demonstrates that environmental enrichment can moderate aggression levels. Heavily planted tanks with broken sight lines reduce stress from seeing their reflection or other tank inhabitants. I've successfully kept crowntails in community settings by providing dense plant cover and carefully selecting tankmates.

Female crowntails display less intense but still present aggression. Sororities (groups of female bettas) can work in larger tanks with adequate hiding spots, though I recommend minimum 20-gallon setups with 5+ females to distribute aggression.

Crowntails demonstrate surprising intelligence and social awareness. They recognize their caretakers, often greeting specific people enthusiastically while remaining wary of strangers. My own crowntails swim to the front glass when I approach but hide when unfamiliar people near the tank.

These fish can learn simple tricks through positive reinforcement. I've trained crowntails to swim through hoops, follow fingers, and even jump for food (though I discourage jumping due to injury risk). Training sessions provide mental stimulation beyond environmental enrichment.

Compatible Tankmates

While crowntails often thrive solo, community setups remain possible with careful planning. Success depends on tank size, layout, and appropriate species selection.

Suitable Tankmates

Ideal tankmates occupy different water levels and lack triggering characteristics like bright colors or flowing fins. In my 20-gallon crowntail community, I've successfully maintained:

Corydoras catfish: Peaceful bottom dwellers that ignore bettas
Kuhli loaches: Nocturnal, hiding during peak betta activity
Ember tetras: Small, fast schooling fish in groups of 8+
Harlequin rasboras: Peaceful schooling fish with subdued colors
Nerite snails: Excellent algae eaters with protective shells
Amano shrimp: Large enough to avoid predation in planted tanks
African dwarf frogs: Peaceful bottom dwellers in 10+ gallon setups

Success requires introducing tankmates before the betta, allowing them to establish territories first. I add crowntails last, reducing territorial aggression toward established residents.

Species to Avoid

Several species prove incompatible with crowntails due to aggression, competition, or fin-nipping tendencies:

Other male bettas (guaranteed aggression)
Gouramis (similar appearance triggers fighting)
Barbs (notorious fin nippers)
Large tetras (may nip elaborate fins)
Angelfish (territorial and may attack bettas)
Goldfish (different temperature requirements)
Crayfish (will attack and eat bettas)

Breeding Crowntail Bettas

Breeding crowntails requires preparation, dedication, and space for raising fry. While rewarding, the process demands significant time investment and multiple tanks.

Pre-Breeding Conditioning

Successful breeding starts with healthy, mature fish aged 4-12 months. I condition potential pairs separately for two weeks, feeding high-protein foods twice daily. Live or frozen foods like bloodworms and brine shrimp improve egg production and milt quality.

During conditioning, I maintain temperatures at 80°F and perform 25% water changes every other day. This mimics seasonal changes triggering breeding readiness. Females develop visible vertical stripes when ready, while males intensify colors and build elaborate bubble nests.

Breeding Setup

I use a 10-gallon breeding tank with 5 inches of water, making nest maintenance easier for males. The setup includes:

Heater maintaining 80-82°F
Gentle sponge filter or air stone
Floating plants or styrofoam cup half for nest anchoring
Indian almond leaves for tannins and infusoria production
Chimney or hurricane glass for female protection

After introducing the female in a clear container, I allow visual contact for 24-48 hours. When both fish show interest—female displaying vertical bars, male building actively—I release her during evening hours when aggression typically decreases.

Spawning Process

The breeding embrace appears violent but follows natural patterns. Males wrap around females, squeezing eggs out while simultaneously releasing milt. This process repeats dozens of times over 2-4 hours, producing 100-500 eggs.

Males collect falling eggs, placing them in the bubble nest. Once spawning completes, I immediately remove the female as males become extremely aggressive protecting their nest. The male tends eggs alone, maintaining the nest and replacing fallen eggs.

Raising Fry

Eggs hatch within 24-48 hours, with fry remaining in the nest another 2-3 days absorbing yolk sacs. Once free-swimming, I remove the male and begin feeding infusoria or commercial fry food 3-4 times daily.

At two weeks, fry can consume baby brine shrimp, crucial for proper growth. I perform daily 10% water changes using aged water to maintain quality without shocking delicate fry.

Around 8-10 weeks, males begin showing aggression, requiring separation into individual containers. This "jarring" process proves labor-intensive—a spawn of 100 surviving fry needs 100 individual containers with daily maintenance.

Common Health Issues and Treatment

Recognizing and treating health problems early dramatically improves outcomes. Most crowntail health issues stem from poor water quality, making prevention through proper maintenance crucial.

Fin Rot

The elaborate fins of crowntails make them particularly susceptible to fin rot. This bacterial infection causes progressive fin deterioration, starting with darkened edges progressing to tissue loss. Poor water quality typically triggers outbreaks.

Treatment involves immediate water quality improvement through daily 25% changes. Mild cases respond to aquarium salt (1 tablespoon per 5 gallons) and pristine conditions. Severe cases require antibiotics like kanamycin or tetracycline following package directions.

I've successfully treated early fin rot using Indian almond leaves, which release beneficial tannins with mild antibacterial properties. Combined with excellent water quality, most cases resolve within two weeks.

Ich (White Spot Disease)

Ich appears as white spots resembling salt grains on body and fins. This parasitic infection spreads rapidly in stressed fish. Affected crowntails often scratch against decorations and display clamped fins.

Treatment requires gradually raising temperature to 86°F over 48 hours, speeding the parasite's life cycle. Combined with aquarium salt treatment, this method proves effective without medications. Maintain elevated temperature for 10 days after spots disappear, ensuring complete parasite elimination.

Swim Bladder Disease

Swim bladder problems cause abnormal swimming—floating, sinking, or swimming sideways. Overfeeding and constipation commonly trigger this condition in bettas.

I treat swim bladder disease by fasting the affected fish for 3 days, then offering a blanched, deshelled pea piece. The fiber helps clear constipation. Reducing feeding amounts and incorporating weekly fasting prevents recurrence.

Velvet Disease

Velvet creates a gold or rust-colored dust appearance on the body. This parasitic infection progresses rapidly, requiring immediate treatment. Affected fish often scratch against objects and display clamped fins.

Treatment involves complete darkness (parasites photosynthesize) combined with copper-based medications. I cover the tank completely for 10-14 days, only uncovering briefly for feeding and medication dosing. Follow medication instructions precisely—copper can be toxic if overdosed.

Prevention Strategies

Prevention surpasses treatment for maintaining crowntail health. My prevention routine includes:

Weekly 25% water changes using treated, temperature-matched water
Quarantine new fish for 2-4 weeks before introduction
Varied, high-quality diet avoiding overfeeding
Stable temperature maintenance with quality heaters
Regular parameter testing catching problems early
Stress reduction through appropriate tank setup and tankmate selection

Understanding why fish die helps prevent common causes of mortality in aquarium fish, including crowntails.

Creating an Enriching Environment

Environmental enrichment significantly impacts crowntail welfare, reducing stress and encouraging natural behaviors. Research indicates that enriched environments decrease aggression and improve overall health.

Plant Selection and Arrangement

Live plants provide numerous benefits beyond aesthetics. They improve water quality, provide security, and create territories. I arrange plants creating distinct zones—open swimming areas, dense hiding spots, and surface cover.

Recommended plants for crowntail tanks include:

Java moss: Creates dense cover and harbors microorganisms
Cryptocoryne: Hardy with broad leaves for resting
Vallisneria: Background plant providing vertical structure
Bucephalandra: Slow-growing with interesting textures
Floating plants: Water sprite or salvinia for surface cover

I maintain 40-60% plant coverage, balancing security with swimming space. Tall plants along the back and sides create backdrop while leaving front areas open for observation and swimming.

Behavioral Enrichment

Beyond static decorations, crowntails benefit from interactive enrichment. I rotate decorations monthly, rearranging layouts to provide novelty. Simple changes like moving a piece of driftwood or adding new plants stimulate exploration.

Feeding enrichment proves particularly effective. I occasionally place bloodworms in a small clear tube with holes, allowing the crowntail to hunt and work for food. Floating ping pong balls provide simple toys—many bettas enjoy pushing them around the surface.

External stimulation through controlled exposure to mirrors or videos of other fish provides mental engagement. I limit these sessions to 5-10 minutes preventing chronic stress while maintaining interest.

Seasonal Care Considerations

While indoor crowntails avoid natural seasonal changes, ambient conditions still affect their care requirements.

Summer Considerations

High ambient temperatures can push tank temperatures above optimal ranges. I combat this by:

Positioning tanks away from direct sunlight
Using fans to increase evaporative cooling
Reducing lighting duration to minimize heat generation
Increasing surface agitation slightly for better gas exchange
Monitoring temperatures more frequently

During heat waves, I've successfully used frozen water bottles floated in plastic bags for emergency cooling. This provides gradual temperature reduction without shocking the fish.

Winter Considerations

Cold weather poses greater challenges, as temperatures below 76°F stress tropical fish. Backup heating becomes crucial—I keep spare heaters and battery-powered air pumps for power outages.

During winter, I:

Use heater guards preventing direct contact with crowntails
Insulate tanks with styrofoam on back and sides
Maintain slightly higher baseline temperatures compensating for heat loss
Check heaters weekly for proper function
Keep tanks away from drafty windows and doors

Advanced Care Topics

Color Enhancement

Diet significantly influences crowntail coloration. Foods rich in carotenoids enhance reds and oranges, while spirulina intensifies blues and greens. I supplement with color-enhancing foods twice weekly, seeing noticeable improvement within 4-6 weeks.

Proper lighting also affects color visibility. Full-spectrum LED lights showcase iridescent scales effectively. I use 6500K daylight bulbs on 8-hour timers, providing consistent photoperiods while highlighting natural colors.

Stress reduction proves equally important for color maintenance. Stressed crowntails display faded colors regardless of diet quality. Maintaining stable conditions, appropriate tankmates, and environmental enrichment keeps colors vibrant.

Longevity and Aging Care

Crowntails typically live 2-4 years with proper care, though I've maintained individuals reaching 5-6 years. As bettas age, they require adjusted care accounting for decreased activity and slower metabolism.

Senior crowntails benefit from:

Slightly warmer temperatures (80-82°F) supporting metabolism
Reduced current allowing easier swimming
Lower water levels reducing surface swimming distance
More frequent, smaller feedings preventing digestive issues
Additional resting spots near the surface
Softer foods accommodating potential dental issues

I've noticed aging crowntails often develop cataracts or reduced vision. Maintaining consistent tank layouts prevents disorientation, and I ensure food lands near familiar feeding spots.

Show Standards and Competition

For those interested in showing crowntails, understanding judging standards helps in selection and preparation. The International Betta Congress maintains specific standards for crowntail evaluation.

Judges evaluate:

Fin ray extension (minimum 33% reduction in webbing)
Symmetry between fins
Color intensity and pattern consistency
Body proportion and condition
Overall deportment and presentation

Show preparation involves 2-3 weeks of conditioning with high-quality foods and pristine water conditions. I gradually acclimate show fish to smaller containers, as most shows display bettas in clear boxes or bowls.

Troubleshooting Common Problems

Lethargy and Loss of Appetite

When crowntails become lethargic or refuse food, I systematically check:

Water parameters—ammonia or nitrite presence requires immediate action
Temperature—verify heater function and actual temperature
Disease signs—examine for visible symptoms
Environmental stressors—new additions or changes to routine
Food quality—check expiration dates and storage conditions

Often, a series of partial water changes and temperature adjustment resolves lethargy. If problems persist beyond 3 days, I consider medication for potential internal parasites or bacterial infections.

Excessive Fin Damage

Crowntail fins prove delicate, susceptible to tearing on decorations or from fin biting. I distinguish between mechanical damage (clean tears) and fin rot (darkened, deteriorating edges).

For mechanical damage, I remove sharp decorations and add Indian almond leaves promoting healing. Stress-induced fin biting requires identifying triggers—aggressive tankmates, poor water quality, or inadequate hiding spots.

Bubble Nest Deterioration

While not building nests doesn't indicate problems, sudden cessation after regular building warrants investigation. Common causes include:

Water flow disrupting surface calm
Temperature fluctuations
Stress from environmental changes
Age-related decrease in breeding behavior

Adjusting filter flow and maintaining stable conditions usually restores nest-building behavior if desired.

Frequently Asked Questions

How long do crowntail bettas live?

With proper care, crowntail bettas typically live 2-4 years, though some individuals reach 5-6 years. Lifespan depends on genetics, care quality, and environmental conditions. Store-bought bettas may be 6-12 months old at purchase, affecting apparent lifespan in your care.

Can crowntail bettas live with other fish?

Yes, crowntails can live in community tanks with careful planning. Choose peaceful, non-colorful tankmates that occupy different water levels. Provide minimum 20 gallons with plenty of plants and hiding spots. Never house multiple male bettas together or combine with fin-nipping species.

How often should I clean my crowntail's tank?

Perform 25% water changes weekly for established tanks. Smaller tanks or higher bioloads may require twice-weekly changes. Test parameters regularly—if ammonia or nitrite appears, increase change frequency. Never change 100% of water unless treating severe disease, as this disrupts beneficial bacteria.

Why is my crowntail betta's color fading?

Color fading typically indicates stress from poor water quality, inappropriate temperature, illness, or inadequate diet. Test water parameters immediately, verify temperature stability, and examine for disease symptoms. Improving conditions and offering varied, high-quality foods usually restores coloration within weeks.

Do crowntail bettas need special food?

Crowntails eat the same foods as other bettas—high-protein pellets supplemented with frozen or live foods. Their elaborate fins don't affect dietary needs, though quality nutrition becomes even more important for maintaining fin health and vibrant colors.

Can I keep female crowntails together?

Female crowntail sororities can work in heavily planted tanks of 20+ gallons with 5 or more females. Odd numbers help distribute aggression. Provide multiple hiding spots and feeding stations. Monitor closely during establishment—some females prove too aggressive for community living.

How can I tell if my crowntail is male or female?

Males display longer, more elaborate fins with pronounced crowning, brighter colors, and visible beard membranes. Females have shorter fins, rounder bodies, and a visible white egg spot behind their ventral fins. Young crowntails can be difficult to sex until 3-4 months old.

Is my crowntail's bubble nest a sign of happiness?

Bubble nests indicate sexual maturity and adequate environmental conditions rather than happiness. Males build nests instinctively when conditions support breeding. While nest building suggests good health, absence doesn't necessarily indicate problems—some healthy males rarely build nests.

What temperature is best for crowntail bettas?

Maintain temperatures between 76-82°F, with 78-80°F being optimal. Consistency matters more than exact temperature—fluctuations exceeding 2°F daily stress fish significantly. Use quality heaters with thermostats and monitor with reliable thermometers.

How do I treat torn fins on my crowntail?

Clean tears from decorations heal naturally with good water quality. Remove sharp objects, maintain pristine conditions, and add Indian almond leaves for their healing properties. Darkened, deteriorating edges indicate fin rot requiring treatment with aquarium salt or antibiotics depending on severity.
