Three-spot Gourami

• It has a labyrinth organ, a chamber of richly veined plates above the gills that lets it breathe air and survive in pools that are almost devoid of oxygen.
• The male builds a nest of bubbles bound with saliva at the surface, gathers the eggs into it one by one and defends it until the fry hatch.
• Its pelvic filaments work as organs of touch with which it explores its surroundings and makes contact with other fish.

• The male builds a nest of bubbles at the surface, bound together with saliva, and defends the eggs until they hatch.
