Bubble Nest

Many anabantoids, including Gouramies, carry out a method of spawning known as bubble nesting.

A 'nest' of bubbles is created by one or both of the parents by taking in air from the surface and creating mucus coated bubbles which stick together to form a foam-like collection of floating bubbles, usually situated between dense vegetation. The eggs are then laid in this bubble nest, cared for and defended by one or both of the parents.
