Are Betta Fish Good For Aquaponics?

One of the most popular fish for aquaponics is betta fish. They are very beautiful and easy to care for, but some myths keep people from considering them as pets. Let’s look at some common questions about bettas for aquaponics systems:

Betta fish require special care and may not be the best choice for an aquaponics system.
The size of your aquaponics system and the tank requirements for betta fish may not be compatible.
Betta fish may also be aggressive towards other fish in the system.
Consider other types of fish that may be better suited for aquaponics, such as tilapia or catfish.

Can You Use One Fish Per Aquaponics System?

You can keep one betta per aquaponics system, but there are a few exceptions. If you have a very large system and want to keep more than one fish, you can do so.

It’s also worth noting that while most people don’t recommend keeping multiple bettas in one tank if you do have multiple bettas or any other type of fish you’ll need to make sure your aquaponics system has enough space for all of them.

Can Bettas Survive In A Few Inches Of Water?

With the right conditions and equipment, bettas can survive in as little as a few inches (centimeters) of water. 

However, they need to be able to breathe, swim, get air and food when needed, and get rid of waste. They must also have an adequate source of oxygen for their gills to operate properly.

In addition to providing these necessities for your betta fish, you must give them enough space so that they can enjoy swimming around freely once in a while — even if this means occasionally getting some exercise from moving around your aquarium! 

As long as you provide what’s needed for a happy home life most importantly oxygenated water then you should have no problem keeping your beloved pet happy for years on end.

Do Betta Fish Prefer To Live Alone Or With Other Fish?

Betta fish are social fish and will do better in a tank with other fish. They thrive on interaction with their kind, so if you want to keep just one betta fish, consider getting two or more. 

You should also make sure that any other species of pet fish you introduce into a tank with your betta is compatible. This can be tricky as different species have different needs and preferences that may not match up completely with yours or those of your new Betta friend!

Bettas are territorial and will defend their territory against other fish. If you do decide to add another species of animal into the mix.

It’s important to give them plenty of space and make sure they don’t feel threatened by each other this could result in aggressive behavior from both parties!

It’s important to note here too: Don’t ever house multiple male Bettas together; they’re likely going to fight each other over territory (which isn’t great for either).

Fish to Avoid in Aquaponics

Fish SpeciesReason to Avoid
Betta fishAggressive behavior and specific water requirements.
OscarsLarge and aggressive, can eat small fish and require a lot of space.
GouramisCan be territorial and require specific water conditions.
ArowanasLarge and predatory, can eat other fish in the system.
PiranhasExtremely aggressive and predatory, not suitable for most aquaponics systems.

Can Bettas Survive Without Food For A Few Days?

If you’re wondering if bettas can survive without food, water, oxygen, and heat for a few days, the answer is yes. Bettas are extremely hardy fish. 

They can survive in both cold and hot temperatures as well as in low-oxygen conditions. Bettas are so tough that they could survive without food or water for weeks!

Do Female Betta Fish Need Separate Tanks From Male Bettas?

You can keep a male betta fish in the same tank as a female betta, but you’ll need to make sure that the tank is at least 10 gallons and has some good filtration. 

It’s generally easier to keep male and female bettas in separate tanks (e.g., if you have multiple male bettas), but they can share an aquarium if there’s enough space and filtration for both fish.

If you’re going to try keeping your male and female betta together, they each must have their territory within the tank. 

You can accomplish this by making sure there are plenty of decorations or plants that provide separation between them; for example, one side could be decorated with plants like Java Ferns while another side is bare gravel or sand (and so forth). 

Another way is by using dividers that allow each fish its section of the water column this will help prevent territorial fighting between them!

Maintaining the quality of the water in your aquaponics system is crucial for the health of your fish and plants. Learn more about how often you need to change the water in your aquaponics system with our informative guide.

Are There Any Issues With Female Bettas And Fry In The Aquaponic System?

As a female Betta fish matures and becomes pregnant, she may become very aggressive toward other fish, including other Bettas. It’s important to keep the tank free of any male Bettas, as they will fight with each other. 

Likewise, you should not mix male and female bettas in one tank unless you are breeding them for their eggs or fry. 

This is because male bettas are territorial by nature; this means that they will guard their territory against intruders by fighting off competitors such as other male or female bettas.

Both species can be kept together if they’re properly segregated when mature but it’s still not recommended if you’re interested in having an aquaponic system with lots of fish and plants!

Will Bettas Eat Smaller Fish?

Yes, bettas will eat smaller fish. Bettas are carnivorous fish that will eat anything that fits in their mouth. This means they will also eat insects and worms.

The good news is that bettas have a fairly small mouth compared to other tropical fish, so they’re not going to be able to consume your entire population of baby goldfish. 

However, if you have any adult guppies or neon tetras in your tank with your betta (or vice versa), be careful! They could end up on the menu for your hungry little friend while he’s looking for his next meal!

Why are Betta Fish Called Siamese Fighting Fish?

Many people are surprised to learn that betta fish are called Siamese fighting fish. They’re called this because betta fish are known to be aggressive and territorial, and they’ve been observed fighting in their natural environments. 

These types of behaviors make them ideal for aquaponics systems where they can have a controlled environment with other fish species that aren’t typically aggressive or territorial.

Catfish are a staple in many aquaponics systems, but what makes them such a great choice? Our guide on catfish in aquaponics can help you understand their benefits, growth requirements, feeding and more.

How Long Do Betta Fish Live For?

Bettas can live for up to 3 years, but the average life expectancy is around 2 or 3.

  • Betta fish are known for their beauty and have become popular pets among people of all ages.
  • In some cases, Bettas have been known to live up to 6 months with proper care.

Fish Suitable for Aquaponics

Fish SpeciesDescription
TilapiaOne of the most popular and hardy fish for aquaponics systems. They grow fast and tolerate a wide range of water conditions.
TroutA cold-water fish that can grow quickly with the right conditions. They require well-oxygenated water and cooler temperatures.
CatfishAnother popular choice for aquaponics systems. They grow quickly and can tolerate a wide range of water conditions.
GoldfishA very hardy and low-maintenance fish that is a good choice for beginners. They are not usually harvested for consumption.
KoiA beautiful and colorful fish that grows large and requires plenty of space. They are not typically raised for consumption.


Bettas are perfect for aquaponics, but you should keep them in separate tanks. They are very territorial and will fight with other fish if they get too close to their personal space. This can lead to injury or death for both parties involved!

Aquaponics offers several benefits, such as efficient use of water and space, reduced need for fertilizers and pesticides, and the ability to grow fresh produce and fish in a small backyard or indoor space.

What types of fish can be used in aquaponics?

Several types of fish can be used in an aquaponics system, including tilapia, trout, catfish, and goldfish. The type of fish you choose depends on your climate, water temperature, and personal preferences.

How do you maintain an aquaponics system?

To maintain an aquaponics system, you need to monitor water quality, nutrient levels, and fish health on a regular basis. This involves testing the water, adjusting nutrient levels, and feeding the fish according to their needs.
