About the Gourami – Species Summary

The Gourami, belonging to the Osphronemidae family, boasts a multitude of species that often grace aquariums with their vibrant colors, patterns, and unique personalities. Hailing from Southeast Asia, these freshwater fish have found homes in tanks globally due to their hardiness and ease of care. Their labyrinth organ, a unique respiratory organ, allows them to gulp air directly, enabling them to thrive in low-oxygen environments. Gouramis have been cherished for their elegant display and calm demeanor. They are a popular choice among both beginner and advanced aquarium enthusiasts.

Gourami Lifespan

Typically, gouramis live between 4 to 6 years. However, with proper care, including appropriate tank conditions, a balanced diet, and regular health checks, they can often exceed their expected lifespan. Like many fish, their longevity is closely linked to their living conditions, making the role of the aquarist pivotal in determining how long their gourami will live.


Gouramis display a dazzling array of colors and patterns. While each species has its distinct aesthetic, a shared characteristic among gouramis is their elongated dorsal and anal fins, which give them a unique silhouette. Species like the Dwarf Gourami can flaunt bright blue and red stripes, while others, such as the Moonlight Gourami, exude a silvery sheen. Their appeal is further elevated by their feeler-like pelvic fins that they use to sense their environment.

Average Size

The size of a gourami can vary significantly based on the species. Dwarf Gouramis might only grow up to 2 inches (5 cm) in length, while Giant Gouramis can reach a staggering 24 inches (60 cm). However, most commonly kept gourami species in home aquariums range between 2-6 inches (5-15 cm).

Gourami Care

Tank Size

For smaller species like the Dwarf Gourami, a minimum tank size of 20 gallons (75 liters) is recommended. For larger species, the tank should be adjusted accordingly. Providing ample space is essential for their well-being.

How To Set Up Their Tank

Gouramis prefer densely planted tanks, replicating the thickly vegetated waters of their native habitats. Incorporating floating plants can be particularly beneficial, as gouramis often build bubble nests using plant debris. Additionally, provide hiding spots using driftwood, rocks, and caves.

Lighting Requirements

Moderate lighting suits gouramis, as it encourages plant growth and allows them to display their vibrant colors without being too intense.


A pH level between 6.0 and 7.5 is ideal for gouramis.


Gouramis thrive in a temperature range of 72°F to 82°F (22°C to 28°C). Consistency in temperature is crucial for their health.

Water Parameters

Soft to moderately hard water is ideal for gouramis. Regular water testing should be conducted to ensure ammonia, nitrites, and nitrates remain at safe levels.

Disease Potential

Gouramis can be susceptible to common fish diseases like ich, fin rot, and bacterial infections. Maintaining good water quality, a balanced diet, and quarantining new tank additions can prevent most ailments.

Food & Diet

Being omnivorous, gouramis have a varied diet. They relish high-quality flakes and pellets, supplemented with live or frozen foods like brine shrimp, daphnia, and bloodworms. Additionally, they appreciate occasional plant matter, including blanched vegetables.

Behavior and Temperament

While generally peaceful, gouramis can be territorial, especially during breeding. Males might display aggression towards other males of the same species. Their curious nature is often evident as they explore their surroundings, using their feeler-like pelvic fins.

Tank Mates

Gouramis coexist well with other peaceful fish of similar size. Tetras, rasboras, loaches, and catfish make good tank mates. However, avoid housing with aggressive or overly active fish that might stress the gouramis.


Breeding gouramis is a fascinating process. Males build bubble nests on the water’s surface using saliva. After a courtship dance, females lay eggs, which the males fertilize and then protect in their bubble nests. Once the fry hatch, they should be fed infusoria or specialty fry foods.
