Bettas Overview

 

The Betta splendens or the Siamese fighting fish are known for being volatile. Even among famous fish relatives like the gouramis, the betta fish stand out for their appearance.

 

The electrifying appearance of their body makes them clear favourites of both novice and advanced aquarists alike. The correct pronunciation of their name is “bet-tah’ fish and not ‘bay-tah’ fish.

 

Bettas are native to the shallow waters of Cambodia, Laos, Thailand, Indonesia, and Vietnam. Their natural habitat has dense vegetation, shrubs, and overhanging trees for extra shade from the sun. Over 70 species of the betta fish have been identified, although most of them live endangered in the wild.

 

Bettas Appearance

In the wild, betta fish have acquired a dull grey-green appearance with short fins; a far cry from the electrifying appearance of the long-finned bettas groomed in aquariums worldwide. Because of extensive interbreeding, there are several hundreds of different color combinations and finnages available.

 

You can find betta fish in a wide range of fins, including delta, double tail, vein, crowntail, Halfmoon, and many more.

 

Popular varieties are always vibrantly colored, and the fins resemble a wedding veil shape. One famous example is the Crowntail Betta. This species has fins covered with extensive spikes, almost like a crown, hence the name.

 

The Veiltail Betta is a common fish that is widely available. The male betta fish of this species have a long tail that swoops downwards. These species come in extensive colour variations, and their overall appearance is spectacular.

 

You’ll notice that the colors intensify and sparkle up when fighting or breeding (as males try to impress a female). Betta fish are a sexually dimorphic species, which means it’s easy to tell them apart.

 

Males are much brighter with well-developed fins and tails, while females are less colorful than the males, but they are attractive in their own right. Most betta fish will reach a length of about 2.3 inches or a maximum of 3 inches, but that’s rare.

 

What do Bettas fish eat?

 

Betta fish are carnivorous species and will need protein-rich food. They would eat animals small enough to fit their mouths in the wild, including daphnia, brine shrimp, mosquito larvae, bloodworms, and even other fish.

 

In-home aquariums, you can choose flake and pellet foods. These can be found in most pet stores and provide betta fish with all the nutrients they need.

 

Most protein-rich options include freeze-dried foods, but you should aim to provide live or frozen foods. All three cases of foods involve other creatures, except that freeze-dried foods have had their moisture and nutrient content removed.

 

Betta fish have been known to eat until there is nothing left, so be careful not to overfeed them. Drop enough food in the tank that can be eaten in 2 to 3 minutes. Feed them twice every day. It is easier on their digestive system.

 

Bettas Temperament

 

Betta fish have a nickname that is based on how they behave. The name ‘Siamese fighting fish’ aptly reflects their tendency to get into fights. They used to be bred specifically for this purpose during the late 19th-century era.

 

Males and females are observed to flare their gills to intimidate rivals. Even when they’re on their own, betta fish will try to establish a territory within the tank and violently defend it if needed. Because of this behaviour, most aquarists prefer to keep these fish singly to avoid extensive aggression.

 

Female betta fish are also very territorial, but they are less aggressive than males – this makes them more suited to a community tank. When they’re not trying to outcompete each other for territory and mates, most betta fish will slowly swim around the tank’s upper and middle levels.

 

Tank Mates: What Fish Can Live with Bettas

 

It is challenging to choose tank mates for betta fish because they are aggressive. In the wild, they prefer to live in solitary confinements, but they may encounter other fish without fighting them, probably because there’s enough space to move around for everyone.

 

Shoaling fish are good companions because it’s hard for them to be bullied repeatedly. They are faster and will be able to escape the territorial Betta fish in case of an attack. You can choose from various tank mates including the Neon TetraCorydoras CatfishKuhli Loaches, Yoyo Loaches, and Glass Catfish.

 

Pro Tip: Avoid introducing territorial species like Oscars because they will fight off Betta fish. You also don’t want to introduce fin-nippers like Tiger Barbs because Bettas have massive fins.

 

Tank Requirements and Conditions

 

Your goal should be to mimic their natural habitat, which is often shallow, warm, and slow with lots of aquatic vegetation. Cover the bottom of the Betta fish tank with sand or fine gravel as a substrate.

 

You will need to install a heater to regulate the temperature around the 75 to 80-degree ranges. The water’s pH value should be about 6 to 8, and the hardness should never be higher than 35 dGH.

 

Since they come from slow-moving waters, you will only need a filter. You don’t need fancy equipment like air and water pumps because betta fish are used to still water. A standard filter will provide small movements in the water, that should suffice.

 

Despite their smaller size, betta fish need around 10 gallons even if they’re kept alone. If you keep them with other fish, make sure to get a much bigger tank to keep the infighting down because male betta fish are always for a fight. Female betta fish can make do with 5 gallons, but more is still better.

 

When cleaning Betta’s tank, make sure to take out a 3rd of the water each time and replace it with fresh water. It allows the fish to quickly adjust to the temperature and pH of clean water while not upsetting their environment’s biological balance.

 

If you keep them in small bowls, make sure to clean the water every 3 to 4 days. If your water has high chlorine quantities, treat it with a few de-chlorinator drops before introducing it to the tank or bowl.

 

Betta fish have gills paired with a labyrinth organ. It allows them to breathe in oxygen from the air. 

It allows them to breathe underwater and air. It explains why fish can survive in harsh shallow waters because their natural habitats tend to evaporate in the drier seasons.

 

Tank Setup: How to Take Care of a Betta Fish

 Since they come from waters with dense vegetation, you should spread a few plant species around the tank. It will provide them with lots of shelter from the sun and improve the water’s oxygen.

 

Pro tip: Keep the surface free of the plants because betta fish often swim to the surface to feed, breed, and breathe in air.

 

You have many options for plants to choose from, including Java Fern, Fava Moss, and Hornwort. They are easy for beginners to care for and resistant to most changes.

 

Recommended Plants for Betta Fish

 

i) Amazon Sword: It’s broad leaves make it a favourite among Betta fish. The Amazon Sword grows to a height of 3 feet, which is quite large. As a result, they could compete for space with your betta fish, which is not a good idea for territorial species. These plants are better suited to tanks that are at least 10 gallons or larger.

 

ii) Anubias Nana: The Anubias Nana is one of the best plants for Betta fish because of its comprehensive, broad leaves. Betta fish have been observed to perch themselves on leaves to sleep and save energy, making the broad leaves of the Anubias Nana perfect for these fish. More importantly, the Anubias Nana doesn’t grow very tall and can stay small enough to fit in a tiny tank (2 gallons).

 

iii) Java Fern: These plants are ubiquitous in most aquarium tanks because they are easy to grow and do well in low lighting conditions. They have a slow growth rate, so you won’t have to trim them now and then like you would with the Amazon Sword and other aggressive growers.

 

iv) Java Moss: Java Moss is just about as famous as Java Fern for a reason. They thrive in all kinds of water settings, are easy to care for, and look pretty good. All these qualities make the Java Moss perfect for beginners. Java Moss doesn’t require intense lighting to grow well and doesn’t need to be rooted in the substrate. It makes an excellent choice for Betta fish growers.

 

Betta Fish Care: Cleaning the Tank

 

 

 

Never clean the tank and its decorations with soap or disinfectant. It will harm your betta fish.

You can clean the decorations with warm water. Alternatively, you can use a small turkey blaster to remove debris from the bottom of the tank. It will prevent excessive bacteria and ammonia buildup.

 

Do Betta Fish Need Light?

 

You might want to invest in some LED lights because betta fish are used to receiving at least 12 hours of sunlight in their natural habitat.

 

Betta fish have pronounced daylight and nighttime cycles. Careful not to provide too much light because it can overstimulate and stress your betta fish out. Stressed fish will have weakened immune systems, making them more susceptible to illnesses.

 

Please do not keep the aquarium close to direct sunlight because it will result in a host of problems for your betta fish. Natural sunlight accelerates algae’s growth and reduces water quality, leading to your betta fish suffering from bacteria and infections. LED lights are the way to go because they mimic natural sunlight without all the side effects of promoting extensive algae growth.

 

Betta fish need around 10 to 12 hours of light and just as many hours of darkness, so make sure to turn off the tank light to promote a natural daytime cycle.

 

As mentioned before, you need to install a filter in the tank. Without a filter, your betta fish will start to become ill and die.

If you want to breed bettas, you would be happy to know that these are dominant tail types over other variations. Therefore, you will have to be more comfortable with producing than different fish varieties – although you will have to be patient because the environment needs to be perfect. Females are easy to identify because they have relatively more dull appearances and less dramatic tails and fins.

 

How to Choose a Mating Pair

 

You should ideally select the best male and female betta fish you currently have. Select betta fish with the characteristics you want juveniles to have, for example, if you wish Crowntail Betta fish, you will need to choose a parent with the coloring you want to achieve.

 

The fish should show no signs of infection or disease. It should be free from parasites and fungus. 

It should be actively swimming around. Make sure fish not lethargic or flying on the floor of the tank.

 

Their eyes should be clear and not bulging. You can check their fins and scales for signs of damage tear, or fungus. The age of the betta fish is also important. Betta should be ideally bred when they are between 4 to 12 months old. Older fish can still produce, but the chances of success won’t be as high as the younger ones.

 

How to Condition a Mating Pair

 

Bettas do not typically breed in community aquariums because of their solitary nature. Your pair will have to be conditioned to ensure that they have enough stamina to withstand the stress they will endure during spawning and courting.

 

The more effectively you condition the pair, the more likely it is for the female to produce enough eggs and the male to have enough energy to care for them.

 

To condition them, you need to feed them enough high-quality food in small amounts, up to 4 times a day. Live foods are the best way to do this. You can use daphnia, chopped meat, daphnia, tubifex worms, and even roaches to do this. If you don’t have live food, you can make do with frozen substitutes.

 

Male bettas create bubble nests at the water’s surface in their aquarium to lure females to the nest.

 

Spawning occurs when the male betta fish wraps himself around the female betta fish, causing her to release her eggs. The male will catch the eggs and places in the bubble nest. Male betta fish have parental instincts and will care for the nest until the fry hatch.

 

Females have been known to eat their eggs, so remove them from the tank as soon as she’s recovered. It is advisable because the male may attack her if he perceives her as a threat.

 

Do Betta Fish Sleep

 

All fish species have to sleep, including betta fish. When they sleep, betta fish typically go motionless. They’re not dead! So avoid tapping at the tank to check if they’re still alive, they may be resting, and you could disturb their routine.

 

How Often Do You Feed a Betta Fish?

 

The feeding frequency for betta fish is two times a day. Feed them once in the morning and once at night to keep them rejuvenated and healthy. Only feed them as much food as they can gobble up in 2 to 3 minutes.

 

Betta Fish Lifespan

 

Most betta fish are known for living for 2 ½ years. However, it’s not uncommon for Betta fish to live for over five years old if the tank conditions are perfect and adequately cared for. If you want to know how to take care of a betta fish, refer to the guide above.

 

Do Female Bettas Become Pregnant?

 

There’s no such thing as a pregnant betta fish because her eggs are laid and then fertilized by the male. That being said, pregnant betta fish will carry her eggs for a brief period and will appear bloated in appearance – but only for a short time.

 

Where to Buy Bettas

 

Many pet stores, online stores, and online forums feature betta fish for sale at a reasonably affordable price. However, if you want to buy rare breeds, you may have to search for specialist breeders. Depending on the rarity of the betta fish, you may have to pay a fortune. However, most betta fish are affordable enough.
