Gourami pearl

The pearl gourami is not only one of the most attractive gouramis but also one of the hardiest and easiest to keep. It is a labyrinth fish, meaning that it can gulp air at the surface of the water and hold it in its labyrinth chamber of the first gill arch, which is a lung-like organ that enables it to breathe air in addition to using gills. Like some other labyrinth fish, the pearl gourami can vocalize; don't be surprised if you hear your pet "talking" with growling or croaking noises, especially when breeding, or fighting with another male. Here's what you need to know about the pearl gourami fish species.
