Betta fish bubble nests

Having a betta fish for a pet is great as not only it requires little maintenance, but it’s also one of the most beautiful fish that you can safely own. One question that I get a lot has to do with betta fish bubble nests. If you own a betta fish, you may notice bubbles forming at the top of the water’s surface. If you are not acquainted with a betta fish, you might even get worried that maybe your pet is sick. Don’t worry! In this article, we are going to cover a few important things that you need to know about betta fish bubble nests.

What Are Betta Fish Bubble Nests?

Again, I want to stress that this is nothing you have to worry about. Your betta fish is perfectly fine. As the name suggests, these bubbles are created by your betta fish and form a sort of nest. If you do see these bubble nests, you can be happy because bettas will only make them if they are healthy and happy. SO why do they make them? The reason why betta fish make these bubbles is for the breeding process. In the wild, habitats can be shallow, dirty and/or with low oxygen levels. These factors hinder the development of the eggs. To get around this problem, betta create bubbles. The bubbles are often clustered on the surface and often attached to leaves of floating debris.


Facts About Betta Fish Bubble Nests

  • The betta fish will often guard the nest that they create. The fish usually waits for a female to spawn with. After the female releases eggs, it’s the male’s job to capture the eggs via the mouth and place it on the bubble nest.
  • By depositing the eggs to the bubble nest, the eggs are in a moist and oxygen-rich environment. These factors are great for the development of the eggs.
  • Keep in mind that a male betta fish will create these bubble nests even if there are no females around. You can say that it’s an instinctive response.
  • Also, there’s no such thing as a “normal” time frame nor a “normal” bubble size. Each betta fish has its own behavioral pattern.
  • Betta fish will create these bubble nest one bubble at a time. They create the bubbles using their mouth. The bubbles they create are mixed with saliva, and that’s the reason why these bubbles don’t simply pop like the bubbles you see in the water (unsoaped water).
