Many betta fish enthusiasts may notice the formation of bubbles around their betta fish tanks. This occurrence often raises questions about whether it is normal or something to be concerned about. In this article, we will explore the reasons behind the formation of bubbles around a betta fish tank and provide insights into whether it is normal or requires attention.

These bubble nests are created by the male betta fish using air bubbles and saliva.

Air bubbles generated by the filtration system can escape to the water’s surface, creating a visible layer of bubbles. This is particularly common in tanks with air stone or sponge filters.
