Surface-Dwelling Fish Species

In addition to natural tendencies, some fish species are known to be surface-dwelling and prefer to stay near the top of the tank. Gouramis are one such species, as they have a labyrinth organ that allows them to breathe air. This organ allows them to survive in poorly oxygenated water conditions, similar to Bettas.
