Why do betta fish make bubbles?
Male betta fish make bubbles only for the breeding process.
They make bubbles at the surface of the water to indicate to the female betta that they are ready to breed and take responsibility for the eggs.
Betta fish keep the eggs inside the bubble nest and protect them from other tankmates and threats.
The male bettas are responsible for protecting the eggs and fry until the fry is ready to swim on its own and leave the nest.
Male betta makes bubble nests to attract the female betta and show their potential to them that they are ready to breed.
Is it normal if my betta fish not making a bubble nest?
Betta fish making bubbles is a sign that they are healthy and happy.
Also, it is a sign to a female betta that they are ready to breed.
However, if your betta fish is not making bubbles, it doesn’t mean they are not healthy and happy.
They will also not make bubbles when they are not interested in mating.
External factors like strong water currents and poor water conditions sometimes make your betta fish stop making bubbles.
What stops betta fish from making bubbles?
All these factors can stop your betta fish from making bubbles:
- Poor water conditions
- Inadequate water parameters
- Strong current flow at the water’s surface
- The age of your betta fish
Poor water conditions
Betta fish are tropical freshwater fish and require clean water conditions to thrive.
Living in poor water conditions will make your betta fish come under stress, and they will become weak.
Weak and stressed betta fish will not be much interested in building a bubble nest.
Inadequate water parameters
Like poor water conditions, inadequate water parameters will also stress your betta fish.
Betta fish building bubble nest is a sign of them being healthy and happy.
Living in water with inadequate and unstable water parameters will make them weak and prone to various diseases and parasites.
In such conditions, your betta fish will not be interested in making a bubble nest.

Strong water flow
If your betta fish tank filter has a strong current flow, especially at the surface, it will be challenging for your betta fish to build a bubble nest.
In strong current flow at the water’s surface, it becomes harder to build a bubble nest as it will break.
Betta fish suffering from an illness will not be interested in making bubble nests.
Look for the signs like clamped fins, red spots, and other behavioral changes like lethargy, avoiding food, and hiding.
Many medical conditions like fin rot and swim bladder disorder will require proper antibiotical medication.
Once your betta fish recovers and start eating and swimming comfortably again, it will start building a bubble nest.

The age of your betta fish
Old age can also be the factor behind your male betta fish not making a bubble nest.
If the water conditions and parameters are good and adequate, and your betta fish is not suffering from any illness, then also, if it is not making a bubble nest, old age can be the reason.
Some bettas can stop making bubble nests after eight months of age, and some can make a good bubble nest even in their third year of age.
So, if age is the factor behind your betta fish not making bubbles, you cannot do anything about that, and all you should do is provide them with ideal living conditions until they live.
How to encourage my betta fish to make bubbles?
Ensuring all these things will help you encourage your betta fish to make bubbles:
- Add a female betta fish to your betta tank.
- Ensure good water conditions.
- Provide your betta fish with adequate and stable water parameters.
- Ensure your filter is set to a gentle water flow.
- Add floating plants to your betta fish tank.
Add a female betta fish.
Male betta fish build the bubble nest to attract female betta fish as they do this to prove to female betta that they are ready to breed and protect the eggs.
If there is no female betta fish in their tank, it is possible that they will not be much interested in making bubbles.
Adding a female betta fish to your betta tank will increase the urge of the male betta to make a bubble nest.
Good water conditions
Betta fish will not be interested in building bubble nests in poor water conditions.
Also, frequent and major water changes can upset your betta fish, and they will lose interest in making bubbles.
Keep your betta tank clean by adding a good filtration system and performing a decent and regular water change of 30% weekly.

Every betta fish has different patterns and timings for building a bubble nest.

Your betta fish will sometimes make a bubble nest on a monthly basis, and sometimes they will make a bubble nest weekly.
Also, sometimes they will form a few bubbles at the surface, and sometimes you will see a good area covered by the inch-thick bubbles.
Also, don’t worry if your betta fish is not making bubbles, as many factors can be responsible for such things. Some of them are water parameters and conditions, and they will not make bubbles if they are not interested in mating.
