It is usually silvery blue in color, and several color varieties are available, including the Opaline and Gold gouramis. (Opaline Gouramis are sometimes called "Cosby" or "Marbled" Gouramis.)

Feeding

Omnivore. The Blue Gourami will accept just about any aquarium fare, including good-quality flakes and freeze-dried foods, frozen foods, such as Daphnia and brine shrimp, as well as live foods, including bloodworms and tubificid worms. Supplement with some type of vegetable-based food. Prized for their appetite for the aquarium pest, Hydra.

Aquarium Compatibility

Should be housed with fishes of similar size and temperament. Best kept in a group of one male to two females—only one male per tank, as they may fight.

Breeding/Propagation

Male builds a bubblenest early in the day.

Notes

If kept with aggressive or fin-nipping species, such as barbs, will spend most of the time hiding in the corners of the aquarium.
