    Betta Fish Basic Characteristics

    According to PSI’s information about bettas, even though they’re different from many other types of fish in many ways, being a feisty fish isn’t the only reason bettas are unique. Bettas are capable of surviving in harsh living conditions that include storm floods, droughts, etc.

    As evolution would have it, these capabilities that betta fish possess helped them adapt further. Even though bettas breathe the air using their gills like most fish, they’ve grown a suprabranchial accessory breathing organ that you may know as the “labyrinth organ.”

    This organ serves the unique purpose of allowing bettas to breathe oxygen directly from the air on the water surface. The remarkable organ and its unique purpose place bettas on a shortlist of just several fish species known as labyrinth fish.

    How Long Do Betta Fish Live?

    Betta fish live between two and four years in captivity, and their lifespan depends on numerous factors. However, betta fish might have a shorter lifespan in the wild due to imperfect living conditions, constant fighting with other males, etc.

    Small ponds, canals, streams, and rice paddies aren’t as clean and healthy as your fish tank can be. If you do your best to keep your tank as healthy as possible for your pet, there’s no doubt your betta fish may live a prolonged and healthier life.

    How Do You Prolong A Betta’s Lifespan?

    Like with everything in life, you can achieve incredible results if you put your mind and effort into it. The same goes with providing your pet betta fish with a prolonged lifespan.

    You should adhere to several methods to help your pet avoid numerous health conditions resulting in a longer and healthier life for your pet. Some of these methods include:

    • Don’t overfeed your betta as it can lead to fatty liver disease;
    • Feed your pet with all the foods its diet requires;
    • Ensure the water conditions are optimal for your betta;
    • Keep the water and tank itself clean according to betta’s requirements;
    • Avoid placing more than one male in the same tank.

    How Big Do Betta Fish Grow?

    Bettas usually grow from 2.4 to 3.1 inches long. On the other hand, under the right conditions when in captivity, your betta may thrive more than that.

    How big your pet will grow depends on multiple factors, including food quality, tank cleanliness, water quality, optimal temperature, genetics, general health, and others.

    You should know that bettas in the wild don’t grow that much. The most they can reach in the wild is around 2.25 inches, which is betta’s natural size.

    Betta Fish Food & Diet

    How Often Do You Feed A Betta Fish?

    As natural carnivores, betta’s diet in the wild includes insects, insects larvae, etc. Essentially, foods rich in protein are what betta’s organism requires. Therefore, it’s essential to provide your betta with its natural dietary requirements. Only then will your pet thrive and have a healthy life.

    Real betta food has the right amount of nutrients your pet needs. When in captivity, betta’s diet also requires protein-rich foods like betta flakes or pellets. Moreover, store-bought betta fish food is easy to portion, so your betta won’t be under or overfed.

    How Often Should You Feed A Betta Fish?

    Your betta fish should get at least two meals a day. If you go with at least two meals a day, and if the tank water has optimal temperature, ensure the pause between the meals is at least six to eight hours.

    If your betta is in its breeding period, or if the water temperature is between 80° – 82° F, you can serve it with up to three meals a day.

    Treats have a significant role for humans, and bettas aren’t any different for loving treats. You can serve your betta with a treat like freeze-dried or frozen bloodworms, leafy greens, or a piece of mango.

    However, ensure you don’t give your pet too many treats so it won’t suffer from bloating. Treat your betta fish with bloodworm once a week as it’s more than enough.

    How Do You Feed Betta Fry And Breeding Fish?

    Aquatic Veterinary Services suggests that feeding should be somewhat different for specific groups of bettas like the breeding ones or betta fry. It’s not overly complicated at all, and it’s just a bit different than what you’re used to when it comes to feeding your regular pets.

    Betta fry or actively breeding bettas require more fat and protein in their diet so they’d adequately grow and develop. Therefore, it’s essential to follow these few simple steps:

    • Each meal should be very small;
    • Depending on the number of betta fry in your tank, feed them with only a few sprinkles or heaps per meal;
    • Feed both groups three to five times during the day.

    How Long Can A Betta Fish Go Without Food?

    A betta fish is capable of going up to two weeks without food. However, keep in mind that your betta will begin to starve after four or five days if not fed.

    Besides stress, lack of food can have other severe effects on your pet’s overall health. In case you don’t feed your bettas for longer than four to five days, it’ll undoubtedly trigger radical changes within their body, including organ failure or numerous diseases.

    Even though a betta fish can survive without food for two weeks, keeping it without food for that long is like pushing your pet to the limit. Some bettas can’t even go for that long as it’s an individual thing.

    Can Betta Fish Eat Human Food?

    Yes, bettas can eat certain human foods. However, you shouldn’t feed your betta with anything from your fridge like chicken or pizza leftovers, etc.

    Considering that betta’s diet should consist of a variety of different foods, it’s essential to learn some basics regarding human food items you can feed your betta with, how much of it should they get, how often, etc.

    Adhering to these simple rules will provide all the nutrients your pet needs while keeping it in the safe zone.

    Therefore, learn more about what bettas eat in the wild and provide them with the same items or their closest alternatives.

    Why Won’t My Betta Fish Eat?

    Your betta might not want to eat due to several reasons. Before resolving the issue, you have to discover why your pet lost its appetite.

    There are several possible answers to why your betta fish isn’t eating. These reasons include water temperature issues, stress, overfeeding, disease/illness, and confusion. It often happens, especially with newly bought bettas, that your fish gets confused and doesn’t realize that the thing you’re giving them is food.

    Do Betta Fish Have Teeth?

    Yes, betta fish have teeth, and their teeth are pretty sharp too. Bettas are known for picking up fights with anyone they come across, especially male bettas and some other fish. Their sharp teeth play a vital role in attack and defense as bettas tend to attack and tear up the enemy’s tail, fins, and scales.

    Besides using them for a fight, betta’s teeth have another use as well. As carnivores, bettas need their sharp teeth to nibble on meat, insects, etc. Killing their prey is essential for their survival, and that’s where their set of teeth comes in useful.

    Betta Fish Tank Conditions

    do betta fish need a heater

    Like every other living creature, betta fish also have their own specific requirements for their habitat. If you’re new to betta fish keeping, you might feel somewhat overwhelmed when you start reading about all the details necessary for them to thrive.

    All fish are different, including bettas. Therefore, they require specific maintenance standards, suitable water temperature, precise pH level inside the tank, filtration systems, etc.

    Don’t think that since bettas can live in shallow pools of water that the small water bowl is an okay home for them as it isn’t! Placing your betta in a larger aquarium will provide your pet with lots of space, and it’s also much easier to maintain.

    Do Betta Fish Need A Filter?

    Betta fish don’t necessarily need a filter. However, having one inside your aquarium will undoubtedly help them live a better life. Having plants as an additional source of filtration next to a filter is advisable, and your tank filtration will go to a whole new level.

    To thrive, betta fish need clean water, just like any other fish. Plants are vital for any tank as they act as natural filters keeping the water clean. Moreover, plants will help create a natural ecosystem in your aquarium, but they’ll also reduce algae growth.

    Additionally, microorganism colonies will develop within the aquarium and in the filter. They’ll help break down any food leftovers and fish waste.

    Here is a great filter for betta fish:

    Do Betta Fish Need A Heater?

    Yes, betta fish need a heater. Bettas prefer a warmer environment with water temperatures ranging from 75° – 84° F as warmer waters allow their cells to properly digest food, resulting in your pet’s proper development and growth.

    Provide your betta tank with an aquarium heater that you can find in any pet store. It’ll help mimic an optimal environment for your pet fish. It’s a known fact that bettas can withstand significant temperature changes and colder waters, but this doesn’t mean they aren’t sensitive to these changes.

    Water temperature below or above the mentioned range can cause various problems to your pet, including slower digestion, stress, breeding discouragement, various illnesses, and others.

    How Often Should A Betta Fish Tank Be Cleaned?

    The cleaning frequency mostly depends on the tank size, but having filters may change how frequently you need to clean your tank regardless of its size.

    Tank cleaning frequency depends on other things too, like how much you’re feeding your bettas and how much they actually eat. It also depends on how much and how often your betta excretes, etc. Having plants in your tank will also influence how often to clean the aquarium, as plants are natural water filters.

    Considering betta’s natural environment, it’s apparent that they enjoy still waters. Therefore, if you have a big fish tank with a filtration system installed, the cleaning frequency will be much lower, but ensure the water currents are slow enough for your betta to feel at home.

    On the other hand, smaller betta aquariums (ex. 4-gallon or a bit larger) require weekly or bi-weekly cleaning, water changes, water purification, etc. By doing so, your aquarium will have low levels of built-up ammonia due to higher oxygen levels in the water.

    Does A Betta Fish Tank Need To Be Cycled?

    Yes, you have to cycle your betta tank. Even though bettas are hardy fish, they aren’t immune to various heavy minerals, gasses, nitrates, etc.

    Here’s a short list with a step-by-step guide of the things you need to do before adding betta to the tank:

    Step 1 – Water conditioning: neutralize harmful elements like nitrates, gases, and others with a water conditioner and leave the tank water to stabilize for 24 up to 48 hours.

    Step 2 – Water stabilization: after all chemicals, gasses, heavy metals, minerals, and other harmful elements are dissolved, water pH levels are stabilized.

    Step 3 – Water temperature & filtration: set the optimal water temperature for your betta (75° – 80° F) and check if the filtration system is set to maintain the slow water flow.

    After finishing all these steps, you can introduce your new pet to its perfect new home.

    What Is The Best Water pH Range For Betta Fish?

    The best range of water pH for bettas is between 6.8 and 7.5.

    The pH (Power of Hydrogen) shows how dangerous the nitrate and ammonia levels within your tank are. Besides, it’s a way of measuring if your water is acidic too much or not.

    A pH scale helps us understand how acidic or basic the water is. This scale ranges from 0.0 – 14.0, and 7.0 is neutral. When water pH is less than 7.0, it means your water is acidic. In contrast, a pH with a higher level than 7.0 indicates the water is basic.

    Most tropical fish prefer neutral pH levels in the water. Therefore, optimizing the pH to suit your betta’s needs is of utmost importance. Pay close attention to strong fluctuations in pH levels so your fish would remain unharmed.

    If you’re looking to get a company for your betta, you’ll need to see if betta pH levels are suitable for potential tank mates as well.

    Keeping the optimal pH range in your betta tank requires you to check pH levels every week and adjust them with a pH adjustment kit if needed. These kits are easy to use, and you’ll find them in almost every pet store or simply get one online.

    What Is The Best Water Temperature Range For Betta Fish?

    The optimal water temperature range for your betta is between 75° – 80° F, and it’s the closest water temperature to tropical waters where bettas come from.

    Even though bettas can cope with lower and higher temperatures outside the optimum range, it’s wise to perform any temperature changes carefully. By doing so, you’ll avoid stressing out your pet which can cause further health complications.

    Male Vs. Female Betta Fish

    male vs female betta fish

    Even though males and females can seem to look a lot alike, it’s not hard to distinguish them, especially if you have any prior experience with bettas. Some differences can help you distinguish male bettas from females, and you just have to be aware of what you’re searching for.

    How Can I Tell The Difference Between A Male And Female Betta Fish?

    It’s possible to tell the difference between male and female bettas in several ways. Some of these differences include behavioral patterns, color differences, the difference in size, and some other features.

    Even though male bettas are feisty little critters, their aggression isn’t focused solely on other males. Therefore, they’ll attack any other fish that’s they can swallow.  

    However, you should note that females are a bit smaller than males. Having a smaller body means females can swim faster to look for the hiding spot. Other than that, they pretty much look alike.

    Besides being tiny fish, bettas are also lone animals, and they’ll stay away from other tank mates as they prefer their solitude.

    Both genders have a membrane right below the gill plate cover known as the opercular membrane. This membrane resembles a “beard” and is shown when bettas flare their gill plates.

    Possibly the best way to tell the difference between males and females is through the opercular membrane. Female betta’s beard is so tiny that it would need to flair its gills to make it visible. On the other hand, male betta’s beard is much bigger, and you can easily see it even without the flair.

    Betta Fish Personality: Male Vs. Female

    Unlike females, male bettas are incredibly aggressive with one another. This violent behavior is one of the main reasons behind their shortened lifespan, and it’s also what gave them their nickname “Siamese fighting fish.”

    For all the reasons mentioned above, it’s essential to ensure you only keep one male betta in the tank, and you can expect it to live much longer.

    Can Male And Female Betta Fish Live Together?

    Yes, male and female betta fish can cohabitate, but under specific circumstances, and even then, it’s not advisable to pair them. If you’re a beginner, putting them in the same tank is acceptable for breeding purposes only.

    After you’ve familiarized yourself with the ways of safe-keeping both genders in the same aquarium without any issues, you can try pairing them for life.

    If you plan on having a male and a female betta fish in the same aquarium, that aquarium has to be lengthy, and it has to be at least 40-gallons (or bigger). That’s the only way of helping your female to stay away from the male betta when the need arises. Still, it also helps to reduce the aggression between them.

    Betta Fish Tank Mates

    betta fish tank mates

    Now that you have a betta you wanted so much, you’re probably thinking about providing your pet with some tank mates. However, you must consider several things before finding out which species are excellent tank mates for bettas.

    Can More Than One Betta Fish Live Together?

    In many cases, multiple betta fish can’t live together. However, there are some exceptions, like pairing a male and a female, or two females. In this case, you have to provide specific conditions so male and female betta could cohabitate.

    If you decide to pair male and female bettas, you have to provide them with a spacious 40-gallon fish tank. In any other case, you should only keep one male betta fish with suitable tank mates in your aquarium.

    Can Betta Fish Live With Other Fish?

    Yes, betta fish can live with other fish, but not with all species. You have to be careful when selecting companions for your pet, as you’d want them to cohabitate in harmony.

    What Are the Best Betta Fish Tank Mates?

    The most suitable tank mates for betta fish are Cory Catfish, Neon Tetras, Harlequin Rasboras, Bristlenose Plecos, Kuhli Loach, etc. However, it’s crucial to provide a big enough aquarium and a specific setup for your betta fish and the chosen tank mates so they could all live together peacefully.

    These several species are some of the best choices for your betta tank, and here’s why:

    Cory Catfish

    There are numerous species of Cory catfish (Corydoras). All of them are pretty calm bottom-dwellers that’ll scavenge the aquarium floor and eat the food your betta left.

    Taking care of them is pretty straightforward, making them a fantastic choice if you’re a beginner fish keeper. Since Corydoras are schooling fish, you should get at least three or even more of them.

    Cory Catfish (Corydoras)

    Care level Easy
    Size Ranging from 1 to 2.5 inches
    Lifespan 5 years or more (with specific conditions)
    pH range 7.0 – 8.0
    Temperature 74° – 80° F
    Tank size 10 gallons at minimum, ideally 20-30 gallon
    Temperament/Behavior Calm / Peaceful


    Neon Tetras

    Neon tetras (Paracheirodon innesi) belong to the Characidae family. With at least a 20-gallon aquarium, you can get a school of Neon tetras as they’re an enjoyable fish to have.

    As a schooling type of fish, you should get at least half a dozen, but getting 12 of them is what you should go for. These fish are pretty peaceful, and taking care of them is pretty straightforward.

    Neon Tetras (Paracheirodon innesi)

    Care level Easy
    Size Around 1 ½ inches
    Lifespan Around 8 years
    pH range 6.8 – 7.8
    Temperature 72° – 76° F
    Tank size 10+ gallon
    Temperament/Behavior Calm / Peaceful


    Harlequin Rasboras

    Harlequin Rasboras (Trigonostigma heteromorpha) share the same natural habitat with bettas, making them a fantastic choice for a tank mate. Since Harlequin Rasboras are docile it means that cohabitation is possible. Even though they’re visually vibrant and fast, bettas won’t chase after them.

    Harlequin Rasboras (Trigonostigma heteromorpha)

    Care level Easy
    Size 2 inches
    Lifespan 5 – 8 years
    pH range 6.0 – 7.5
    Temperature 73° – 82° F
    Tank size 10+ gallon
    Temperament/Behavior Peaceful


    Bristlenose Plecos

    Bristlenose Plecos (Ancistrus), a.k.a. the Bristlenose catfish, is a hardy fish which makes it a fantastic choice for beginners as they’re very easy to care for. They can easily live with a betta because they’re pretty docile fish.

    Bristlenose Plecos (Ancistrus)

    Care level Easy to Medium
    Size 3 to 5 inches
    Lifespan 5 or more years
    pH range 5.8 – 7.8
    Temperature 73° – 81° F
    Tank size 20+ gallon
    Temperament/Behavior Peaceful


    Kuhli Loaches

    Kuhli Loaches (Pangio kuhlii) are very odd, eel-like scavenger fish. Scavenging makes them an excellent choice as they’ll pick up any food leftovers your betta doesn’t eat.

    They’re nocturnal, which makes them an excellent choice since, in the daytime, they’ll hide together in groups, and they’ll come out of their hiding spot when the lights are off.

    As bettas tend to sleep at nighttime and Kuhli Loaches operate during the night, they get along just great. The different habits Kuhli loaches have makes them excellent tank mates for even more aggressive bettas.

    Kuhli Loach (Pangio kuhlii)

    Care level Medium
    Size 2 ¾ up to 4 inches
    Lifespan 10 or more years with proper care
    pH range 5.5 – 6.5
    Temperature 75° – 86° F
    Tank size 20+ gallon
    Temperament/Behavior Peaceful


    Can Betta Fish Live With Shrimp?

    Yes, betta fish can live with some shrimp species, including Amano, Red Cherry, and Ghost shrimp. However, it’s essential to develop a specific tank set up to accommodate the betta and shrimp species you choose.

    Amano Shrimp

    Amano shrimp (Caridina multidentate) is a peculiar critter that fits perfectly into the betta’s environment. The one thing that’s worth mentioning is that this Amanos won’t take over the tank as they can’t breed in a freshwater environment.

    As mentioned in Betta Care Fish Guide, Amanos aren’t visually triggering to bettas, and they’re also quite large, making them less appealing as a meal. Another reason why this species is an excellent choice for your betta tank is the fact that this species is very peaceful by nature. It’ll hide during feeding and clean your aquarium from algae.

    Amano Shrimp (Caridina multidentata)

    Care level Easy
    Size 2 inches
    Lifespan 2 – 3 years
    pH range 6.0 – 8.0
    Temperature 68° – 86° F
    Tank size 10-gallon for five shrimps and one Betta
    Temperament/Behavior Peaceful


    Red Cherry Shrimp

    Red cherry shrimp (Neocaridina davidi) is a quite active but peaceful species requiring plenty of hiding spots throughout the tank. Even though they grow up to one inch, your betta might try to eat them if it hasn’t been fed in a while. Therefore, ensure betta’s belly is full to save your shrimp population.

    Speaking of Red cherry population, they can reproduce quickly and might take over the tank in a couple of months. Even though they’re perfect algae-eaters that’ll keep your tank clean, it’s wise to control their breeding before it’s too late.

    Red Cherry Shrimp (Neocaridina davidi)

    Care level Easy
    Size Around 1.6 inches
    Lifespan 1 – 2 years in ideal conditions
    pH range 6.5 – 8.0
    Temperature 57° – 86° F
    Tank size 5-gallon for ten shrimps and one Betta
    Temperament/Behavior Active and peaceful


    Ghost Shrimp

    Ghost shrimp (Palaemonetes paludosus) is excellent for beginners. They can grow up to one and a half inches meaning your betta won’t eat them.

    Even though this shrimp species is peaceful, there’s something that might stir things up within your betta tank. Considering that ghost shrimp reproduce incredibly fast, it’s likely that your betta will feast on their offspring keeping the population at bay.

    Besides potential overpopulation, this species is a perfect tank mate for your betta as it’s incredibly docile, and your betta won’t even notice it’s there.

    Additionally, ghost shrimp and betta fish require very similar water conditions. Therefore, they’re an excellent match for your betta aquarium.

    Ghost Shrimp (Palaemonetes paludosus)

    Care level Easy
    Size 1 ½ inches
    Lifespan 1 year
    pH range 7.2
    Temperature 75° F
    Tank size 5-gallon for ten shrimps and one Betta
    Temperament/Behavior Peaceful


    Betta Fish Health & Illnesses

    betta fish illness

    I’ll lead you through some of the most common health issues that betta may suffer from, but I’ll also cover some strange behaviors, their sleeping habits, etc.

    How Do Betta Fish Sleep?

    When sleeping, bettas are still, and they sleep with their eyes open as they have no eyelids. Like other fish that are active during the daytime, bettas tend to sleep at night.

    Moreover, bettas might sleep in various positions, including sleeping on the side, sleeping with their heads down, sleeping vertically, or even curled up.

    How Long Do Betta Fish Sleep?

    Betta fish sleep for about 8-12 hours a day. Having a betta is similar to having a teenager, at least when it comes to sleeping habits. Mainly, bettas are day-dwellers that tend to do most of the sleeping during the night. However, in case they are active during the night, they’ll need to take short naps during the day to replenish their energy. Sounds familiar?

    Bettas prefer to sleep in the dark. Therefore, make sure that any tank lights you have are turned off in the evening. According to Aquarium Source, you can easily start their circadian cycle by providing them with ambient lighting even if the lights in your room are on.

    Another similarity to teenagers is that bettas can sleep through “entire day” (or night, if you will), and their sleep ranges anywhere from eight up to twelve hours (both weekends and on school nights).

    Inactivity or lots of sleep during the day usually indicates that your fish has some health issue. If your betta sleeps all day long, it may be sick if it doesn’t have the ideal living conditions it requires. Therefore, keep your eyes open for any suspicious signs in your betta.

    Why Is My Betta Fish Swimming Sideways?

    Betta fish can swim sideways for various reasons like resting, boredom, laziness, or some illness. Even though bettas have quirky personalities, newbie fish keepers may think of this behavior as if there’s something wrong with their fish when they’re swimming sideways.

    However, you should never forget that bettas actually enjoy laying in various and strange positions. Moreover, they prefer to swim sideways and sometimes float, and they do this when they’re bored and because they’re lazy swimmers.

    The next time you get various ideas about what’s going on with your pet bear in mind that it just might be resting, and it went for a sideways position to do so. But if you notice that this happens often, you should check if your betta suffers from any illness.

    Suppose the water flow in your aquarium is minimal and your fish swims sideways continuously along the gravel. In that case, there’s a possibility it suffers from a swim bladder disease.

    How Can You Tell If A Betta Fish Is Sick?

    You can easily spot if your betta is sick, thanks to various symptoms you’ll notice if you care to pay close attention. These common betta diseases may significantly decrease your pet’s quality of life. Therefore, it’s essential to cure your betta of Popeye or any other condition as they can be fatal if left untreated.

    Signs that should keep you alarmed are numerous and include bulging eyes, decreased appetite, unusual lethargy, and muted or faded colors.

    Also, if your pet picks its fins and rubs them on the substrate, or if it can’t swim as it usually does, or even if it has damaged scales or fins, you might want to look for solutions.

    In the table below, I’ll mention the most typical betta fish diseases, including their symptoms, causes, and potential treatments.





    Tail or fin rot
    Receding fin edges, black or red coloration on the poorly conditioned fin or tail  

    Bad water quality

    Administer aquarium salt and clean the water
    Swim Bladder Disorder Difficulty to regulate depth or swimming, floating on the side Bacterial infection, genetics, or overfeeding Fasting for several days and some antibiotics may be required
    Columnaris Cotton-like growth along gills/body Low water quality, stress Anti-fungal medication, clean water



    Swollen eye

    Tuberculosis or prolonged poor water quality exposure Clean tank water and possibly antibiotics
    Ich (Ick) Little white spots on fins and over the body, rubbing body on décor Contagious tank mates, low water quality, stress Parasite treatment and clean water
    Hole in head Holes above eye sockets Poor water quality and inadequate nutrition Proper betta food and clean water


    Why Is My Betta Fish Turning White?

    Your betta may turn white or lose its colors due to numerous factors. Even though most of these factors are environmental, they may also happen because of various reasons. These reasons include your pet’s age, changed water parameters, illnesses like fin rot, anchor worms, columnaris, or increased stress level.

    You can help reduce this discoloration with improved lighting, changing substrate with a darker one, and providing your fish with high-quality and diverse foods.

    Why Is My Betta Fish Not Moving?

    Your betta fish might not be moving for various reasons. Sometimes these reasons are benign, meaning your pet is resting or sleeping on its sides, and that’s why it isn’t moving.

    However, your betta might seem immobilized due to improper feeding or bad water quality. Also, your pet may be suffering from illnesses like constipation or swim bladder that rendered it completely immobile.

    Ultimately, the last reason why your betta may not be moving is – it passed away.

    How Can I Tell If My Betta Is Stressed?

    You can tell if your betta is stressed by paying close attention to stress-related symptoms in betta fish. The signs you should look for include hiding, decreased appetite, discoloration (change in color), irregular swimming patterns, lethargy, strange behavior, etc.

    Also, things that cause stress in betta fish are overcrowded aquariums, sudden changes in water parameters, illness, etc. Suppose you encounter any of the mentioned symptoms. In that case, you should try and figure out what’s causing them and act immediately to help your pet and provide it with a stress-free life.

    What Are Some Good Tips To Keep Betta Fish Healthy?

    Good tips to keep your betta healthy include a clean tank, scheduled feeding with nutritional betta food, optimal water hardness, temperature, and many others.

    Stress plays a massive part in your pet’s overall well-being. Therefore, you have to ensure your betta isn’t stressed so it’d avoid various stress-related diseases.

    Make sure to provide your pet with aquarium décor that’s suited for its delicate fins. Hard surfaces and edges can easily hurt betta’s fins when it swims through and around those objects.

    Also, bettas love resting on containers or other objects on the bottom, so make your fish happy by providing it a nice resting place.

    Ultimately, interact with your pet and enjoy its company so it would enjoy your presence as well. Remember – a happy pet is a healthy pet!

    Other Frequently Asked Questions

    stay at the top of the tank

    Let’s go through some other frequently asked questions betta keepers tend to ask.
