Hailing from the tropical waters of the Far East, Blue Gouramis are one of the most hardy of the Gourami family. Their preference is for thickly vegetated waters of any type. They can be found in ditches, canals, ponds, swamps, rivers, and lakes. Blue Gouramis tolerate a wide range of temperatures and are not demanding in terms of water conditions. However, they prefer soft, slightly acidic water when in breeding season.In the home aquarium they may be housed with a variety of fish, although it's usually best to keep them with fish of similar size. Generally only one male should be kept per tank, as males are highly territorial. However if the tank is large enough, or there are enough other fish present, this natural tendency will be diminished.
These are exceptionally easy fish to feed, as they will accept virtually any foods, from flake to freeze-dried, to live foods. They will consume hydra voraciously, and are prized for their ability to eliminate this pest from the home aquarium.
Adults reach up to five inches in length, and females are slightly larger.
Blue Gouramis are among those fish who possess a labryinth organ, which allows them to breath air directly.
