Betta Fish Care: Tank Size Filtration Heating Diet and More

Betta Fish CareBetta fish are a popular choice for fish enthusiasts due to their vibrant colors and unique personalities. Commonly known as Siamese Fighting Fish or Gouramis, Betta fish originate from Southeast Asia and are known for their ability to survive in stagnant waters.

In this article, we will explore Betta fish care, including male and female differences, international congress, tank size and filtration, and major factors for Betta fish care.

Male and Female Differences

Male bettas are known for their bright and bold colors and luxurious fins. They also have a more pointed body shape and a longer anal fin.

Female bettas, on the other hand, tend to have more subdued colorings and shorter fins. One of the most significant differences between male and female bettas is the ovipositor, which is a small tube located under the female’s belly.

This tube is used to deliver eggs during the breeding process.

International Congress

The International Betta Congress (IBC) is dedicated to promoting Betta fish shows and competitions. The IBC hosts an annual convention that attracts breeders and enthusiasts from all over the world.

Show bettas are judged based on factors such as overall appearance, color, and finnage. Betta fish enthusiasts can learn about breeding techniques and new genetics trends at the convention.

Major Factors for Betta Fish Care


The housing condition is the most important factor that affects the overall health and happiness of Betta fish. The minimum tank size for a healthy living environment is a five-gallon tank.

MarinoLand and Fluval are two manufacturers known for their high-quality fish tanks.


A filtered tank is essential for providing good water conditions, keeping the water clean and free from pollutants, and maintaining the nitrogen cycle. Fish bowls are not suitable for Betta fish as they lack proper filtration.

Power Filters like Penn Plex Power Filter and AquaClear are good for Betta tanks, and they make sure that the water is well-filtered to prevent harmful bacteria and algae growth.


Betta fish need to live in an adequately warm environment, and an aquarium heater is necessary to maintain the ideal temperature range which is between 75F-82F. Sudden temperature changes can harm the fish, so it’s important to monitor the water temperature regularly.


Betta fish benefit from having caves, or ornaments in their environment to provide cover and a place for them to hide and rest. Live plants such as java moss and anubias are a great addition to Betta environments as they provide both decoration and a place for the fish to rest.


Betta fish are carnivorous and prefer a diet of live or frozen food. For example, bloodworms, brine shrimp, and daphnia are ideal for Betta fish.

Pelleted food is also a good option, but it should be supplemented with live food to meet the nutritional needs of Betta fish.

Tank Mates

Male bettas should not be housed with other male bettas, as they are territorial and can become aggressive towards each other. Female bettas can live together, but it’s essential to monitor them closely.

Betta fish can live with certain species of fish like neon tetras and cory catfish, but it’s important to research the specific type of fish before introducing them into the Betta environment.

Proper Tank Size for Betta Fish

A five-gallon tank is the minimum requirement for Betta fish. A smaller tank is not appropriate for Betta fish.

In a smaller tank, the water becomes dirty more quickly and does not provide enough swimming space. A larger tank is also beneficial and recommended for Betta fish.

An optimal tank size is 20 gallons for a Betta fish community. Tank dividers are a suitable option to keep more than one betta fish in a larger tank.

Importance of a Filtered Tank

A filtered tank helps to maintain clean water and provides a healthy environment for Betta fish to live in. A fishbowl or an inadequately filtered tank can lead to stagnant water, which attracts harmful bacteria and parasites.

A good quality filter creates the right amount of turbulence, oxygenates the water, and helps to maintain a stable nitrogen cycle that benefits the overall health of the Betta fish.


In summary, Betta fish are beautiful creatures that require proper care to live a happy and healthy life. Their care requires specific housing, filtration, heating, decor, diet, and tank mates to ensure their well-being.

A five-gallon tank is a minimum requirement, while a larger tank can provide more swimming space. Betta fish should not be housed with other male bettas, and it’s essential to monitor them regularly.

A filtered tank is crucial to maintaining clean and healthy water for the Betta fish to live in. Adequate attention and care can provide a long and fulfilling life for these stunning fish.

Aquarium Filtration

Bettas Need Proper Filtration

When it comes to Betta fish care, filtration is one of the most crucial factors. Proper filtration can prevent your Betta fish from suffering from a range of health problems caused by poor water conditions.

A common misperception is that water changes are sufficient for maintaining a healthy environment for Betta fish. This is not true, as Betta fish require proper filtration to remove physical and chemical waste, as well as the conversion of ammonia to nitrites and then to nitrates through the nitrogen cycle.

A popular filtration system for Betta tanks is the sponge filter. It is gentle and effective and provides excellent biological filtration by encouraging the growth of beneficial bacteria that help control nitrate levels in the aquarium.

Similarly, power filters like Penn Plex Power Filter and AquaClear are also an effective choice for Bettas, providing both mechanical and biological filtration. The Aquael Multikani power filter is a great solution for Betta tanks.

This filter comes with a magnetic impeller that is safe and provide smooth operation. It also has a high-quality ceramic shaft that reduces friction, making it noiseless.

The Aquael Multikani filter is quite efficient and has a flow rate of up to 300 liters per hour, making it perfect for aquariums above 5 gallons.

Protecting Your Betta from the Filter

Betta fins are delicate and easily damaged. The flow from some filters can be too strong for Beta fish, which can potentially harm them.

Further, Betta fish are curious creatures and can easily get stuck in the filter. This can lead to severe injuries or even death.

An excellent way to minimize the water flow in the aquarium is by using flow adjustments. A flow adjustment valve allows the water flow to be adjusted based on the requirements of your Betta fish.

Moreover, you can use a pre-filter sponge over the water intake section of the filter to prevent Betta fish fins from getting sucked in. Tank

Heating (Water Temperature)

Bettas are Tropical Fish

Betta fish are tropical fish and require warm water temperatures to survive.

The ideal temperature range for Betta fish is between 75F-82F. Fluctuations in temperature, especially sudden changes, can negatively impact their health and wellbeing.

An aquarium heater is, therefore, an essential item for any Betta tank. Eheim and NeoTherm are two popular brands of aquarium heaters that are suitable for Betta tanks.

Eheim is known for its innovative technology and precision heating, while NeoTherm features a highly accurate temperature sensor that can be controlled digitally. Both brands are available in various wattage options to fit the size of your Betta tank.

It is essential to use a reliable digital thermometer or aquarium heater controller to monitor and maintain the right temperature in the tank. Digital thermometers provide accurate temperature readings and are easy to use.

Aquarium heater controllers offer added safety by automatically turning off the heater if the temperature becomes too high, preventing the water from becoming too warm. In conclusion, taking care of Betta fish requires proper filtration and heating.

Bettas need a healthy and stable environment with regulated water flow and temperature that does not stress them. The right type of filter and aquarium heater can help keep the Betta tank clean, healthy, and optimal for their wellbeing.

Additionally, adding a flow adjustment valve and pre-filter can protect the fish from dangerous currents and getting stuck in the filter. By taking care of your Betta fish, you will ensure that they can thrive in their environment.

Tank Decorations

Selecting Plants for Betta Fish

Betta fish are known to appreciate having plants in their environment. Live plants such as java moss, anubias, and wisteria not only provide decoration, but they also help keep the water clean and provide hiding places for the Betta fish.

Artificial plants, silk plants, and plastic plants are great alternatives to live plants. These plants can enhance the beauty of the Betta aquarium while being easy to maintain.

Plants are essential to Bettas and can assist in reducing the quantity of nitrates in the water and thus maintaining a healthy environment. Bettas prefer floating vegetation or plants that grow from the bottom.

Planted aquariums provide natural cover for Bettas to retreat to when feeling stressed and creates a natural look and feel.

Hardscape for Betta Fish

Hardscape is essential in any aquarium and can add to its aesthetic value. Bettas enjoy hiding spots created by hardscaping in the aquarium.

Rocks, branches and coconut shells, are all great additions to any Betta environment. Branches provide a comfortable hiding space for Betta fish, and rocks create great stepping stones while allowing for the Betta to venture deeper into the aquarium.

Avoiding Sharp Edges and Small Holes in Decorations

When selecting decorations, it is important to consider the safety of your Betta fish. Decorations with sharp edges and small holes can cause injury or harm to your Betta fish.

Delicate fins are especially susceptible to damage, which can lead to health problems. It’s best to avoid any sharp or jagged edges in hardscape material such as rocks, and if you are going to place decorations in the tank, ensure the holes are large enough for your Betta to swim through.

Diet (Feed Them Right!)

Food Hierarchy in the Aquarium

In the aquarium, there is a food hierarchy determined by the type of food offered to the fish. Frozen food, freeze-dried, pellet, and flake food are the most commonly offered foods.

Frozen food is at the top of the hierarchy due to its high nutritional value. Freeze-dried is the next best option, followed by pellets and flake food which are at the bottom of the hierarchy.

Recommended Foods for Betta Fish

Betta fish are carnivorous fish and require a diet that is protein-rich. Frozen bloodworms, blackworms, and daphnia are all excellent choices for Betta fish.

Always remember to thaw frozen food before feeding it to the fish. VitaChem is a great vitamin supplement that can be added to the fish’s diet to enhance their colours and promote overall health.

NorthFin’s Betta Bits Food is another great choice and is formulated specifically for Betta fish. Live Food for Betta Fish – Pros vs.
