Some Steps for Building a Healthy Bubble Nest

If you want to build a successful bubble nest, you must follow some steps to ensure the healthy breeding of bettas.

What you’ll need–

  • Tank
  • Water
  • Filter
  • Temperature
  • Decoration
  • Floating item
  • Female betta
  • Test

How to do

Choose the Perfect Tank.

Try to pick a perfect-sized tank to ensure a healthy environment. As bettas are aggressive species, you must choose a big mating tank.

Bettas need more space for breeding and making bubble nests. Otherwise, a tiny tank is not suitable for breeding activities.

Keep the Water Clean.

Make sure that the tank water is clean enough. Try to clean the water weekly to avoid a dirty environment. Clean the water carefully by separating the bubble nest with a spoon in another tank.

High humidity and tannins make the water sticky and help keep the nest together.

See the Filter

Ensure to avoid the high water movement and wind of the filter as it breaks the bubble nest.

Keep an eye on the water’s surface to make bubble nesting successful.

Maintain the Temperature

Make sure to control the temperature according to the needs of betta breeding. Choose the perfect heater for the tank and maintain the temperature between 78 to 82 degrees.

The temperature should not be very high for bettas. Otherwise, they can’t breed properly.

Decorate the Tank Nicely.

Make sure to use light and plants appropriately in the tank to make the environment more natural.

A good environment and location will help the bettas in their happy breeding.

Use a Floating Item.

You need to use a floating item on the tank’s surface to provide the bettas’ security. Make sure to use a lid or styrofoam on the surface level to ensure the safety of bubble nests.

You need to select a non-toxic float for bettas’ health.

Put a Female Into the Tank.

When the male betta creates a bubble nest with his saliva, you can put a female betta for mating. Male and female bettas can only stay together when they mate; otherwise, they will fight as they are aggressive species.

Make sure to remove the female betta from the tank after mating and put it in another tank.

Balance the Water

You need to do some tests to balance the ph level of the water and other water parameters. 

Pick the box of testing stripes as it is not costly and affordable, and do the tests to ensure the health of bettas.

Why Do Bettas Keep Eggs in a Bubble Nest?

Bettas keep their eggs in a bubble to ensure their security of the eggs. Bubble nests are a safe place for bettas to raise their eggs.

The other name of betta fish is Labrinth, which originated from a warm tropical climate and stagnant water. This species has low oxygen in the water, and it helps to create bubble nests by using the saliva of male bettas.

So, they always prefer bubbles to survive as they belong to a vulnerable environment.

How Are the Conditions for Breeding?

When a male betta wants to mate, he finds the best location and creates a bubble nest on the water’s surface to attract a female betta. 

If the female betta agrees, she goes for mating, and the male betta collects eggs and puts them into the nest, which the female betta drops.

You need to provide extra breeding foods to promote bettas’ strength, nutrition, and egg growth. Make sure to keep the water clean.

Why Does a Male Betta Make Bubble Nests?

When the male betta has enough maturity for reproduction, they start to make bubble nests and wait for mating. 

Male bettas do the majority of the breeding process. They make the bubble nest, collect the eggs from the female betta with their mouth, take care of the fertilized eggs by providing eggs with adequate oxygen to raise them, and nurture the young hatches.

Male bettas enjoy the activity of making bubble nests. Sometimes they build a vast nest to avoid their boredom.

How to Introduce the Female Betta?

Put the male and female betta in a tank to make the attraction between them. As they are aggressive species, keep your eyes on them to avoid the fight.

If the male betta can impress the female betta, and she shows any positive hints, the male betta feels so excited and starts to flare his gills to show his happiness and make love.

After mating, separate the female betta again for her safety; otherwise, she may try to eat the eggs.
