bubble nest
Foam egg cradle
A bubble nest is a floating cluster of mucus-coated air bubbles built by certain fish, especially bettas and gouramis, as a site for breeding.
The male typically constructs the nest at the water's surface and guards the eggs deposited there: The betta blew a bubble nest in the corner of the tank.
