In light of some disagreement about what bubble nests really mean in a betta, here are some things to know.
Bubble nests are clumps of bubbles floating on the water surface of the tank, created by the betta fish gulping air from the surface to then exhale the oxygen, covering it in saliva. The saliva makes the bubbles hold better. This nest is to keep betta eggs safe, giving them the oxygen and clean water they need until they are ready to hatch. Bubble nests may be large, small, thick or thin, depending on the betta's personality and environment. Bettas will also use plants and other floating debris to build their nests, often building under leaves. When making bubble nests the betta will often work rapidly, for hours until the bubble nest is finished.

Male bettas make bubble nests when they breed with a female betta, even luring female bettas under their nest to spawn. They can then place the eggs securely in the oxygen filled bubbles, guarding them until they hatch and can swim on their own. The male betta will pick up eggs in his mouth and place them back securely in the bubbles should any of them fall.
Female bettas will also make bubble nests. They can then release unfertilized eggs into the bubbles. Female bettas will likely eat these unfertilized eggs.
Bettas will create bubble nests at random, when they get the urge. It may be triggered by the presence of another female or male betta fish. The conditions also have to be just right, warm water, very little filter flow, and of course very clean water.

Is bubble nesting a sign of a happy betta? Yes and no. If your betta is making a bubble nest, it's likely he is happy with his conditions because they are appropriate for housing fry. A great compliment to all the work you have put in to making his aquarium just right! However, it is still a breeding habit, so if your betta isn't making one, it doesn't necessarily mean he isn't happy, that depends on his water condition and health. And even if they are making bubble nests, water should be tested as usual and cleaned just as you would regularly. Bettas can also make bubbles when they are sick, they will be larger and scattered rather than in a nice neat clump. They will also show signs of being sick, such as lethargic, floating at the top or sinking to the bottom, or not eating.
To encourage bubble nesting, warmer temperatures make better bubble nesting. Never above 82 degree Fahrenheit. The filter flow must be minimal, this can be done by blocking the water flow with filter media, and keeping the water level high so the water doesn't splash. Plants add an element for the betta to work with when making bubble nests. Bettas will also be encouraged to make bubble nests when another betta is around, but this should not be done often or for long periods of time as it will stress them.
And of course do not let a bubble nest discourage you from cleaning the tank! Bettas have a knack for building the biggest bestest bubble nest on cleaning day. The health of the betta is much more important than a little tantrum. They will build a new one. If you still want to keep their nest, use a plastic cup to pick up the bubble nest, clean the tank like normal, then carefully place the bubble nest back into the tank.
And of course be proud of your little boy or girl for building a bubble nest! They worked hard on it, and it is quite adorable.
Happy Bubble Nesting!
