Silver Gourami – Trichopodus trichopterus

Among labyrinth fish kept in home aquariums, the Silver Gourami (Trichopodus trichopterus) has earned a special place thanks to its calm temperament, intriguing behavior and remarkable adaptability. This species is an excellent choice for aquarists who want to build a peaceful community tank, while still enjoying interesting interactions and subtle beauty. In this article you will learn how to properly care for Silver Gouramis, how to set up a suitable aquarium and how to keep these fish healthy and active for many years. MB Store supports enthusiasts at every step by offering quality aquariums, filtration systems and essential aquarium equipment tailored to the needs of gouramis and their tank mates.

Natural origin and characteristic features of Silver Gourami

The Silver Gourami, scientifically known as Trichopodus trichopterus, comes from Southeast Asia, where it inhabits slow flowing rivers, rice paddies, marshes and densely vegetated ponds. In the wild, these waters are often warm, soft and slightly acidic, filled with roots and aquatic plants. Such environments are relatively poor in oxygen, which explains why this species developed the labyrinth organ, enabling it to breathe atmospheric air directly from the surface.

The body of the Silver Gourami is laterally compressed and elegantly elongated, usually reaching 10–15 cm in aquariums, though in spacious tanks larger specimens can appear. The base body coloration is light silver, often with a delicate bluish or greenish sheen depending on lighting. Two darker spots along the flanks, one mid‑body and one near the tail, are typical and often used as an identification mark for this species and its colour morphs.

One of the most fascinating features of the Silver Gourami is its long, thread‑like pelvic fins, which function as tactile organs. With their help, the fish explore the environment and “feel” other inhabitants of the tank. This behavior fascinates observers and gives these gouramis a strong presence in the aquarium, even though their colors may be more subtle than in some other ornamental species.

Sexual dimorphism is visible, especially in well conditioned adults. Males usually have a more pointed and elongated dorsal fin, while the dorsal fin of females is shorter and more rounded. Males may also display slightly more intense coloration, particularly during breeding season. Recognizing the sexes correctly is essential for those planning to maintain a small breeding group or encourage natural reproduction in a dedicated tank.

Behavior, temperament and compatibility with other fish

Silver Gouramis are generally considered peaceful, but they display a complex social structure and territory awareness. Adult males may show mild aggression toward one another, especially in smaller aquariums or when there are few visual barriers. For this reason, it is usually recommended to keep one male with several females, or a group of young individuals that grow up together in a well planted, spacious tank.

Despite occasional displays of dominance, Silver Gouramis are suitable for community aquariums. They coexist well with calm, similarly sized fish that do not nip fins and do not inhabit exactly the same water level aggressively. Good tank mates include many tetras, rasboras, peaceful barbs, livebearers and small catfish such as Corydoras. It is advisable to avoid combining them with very aggressive cichlids or hyperactive species that constantly harass other fish.

These gouramis usually occupy the middle and upper parts of the aquarium, frequently approaching the surface to breathe. Their swimming is unhurried and elegant, and they enjoy leisurely exploring vegetation. The use of the long pelvic “feelers” is especially captivating, as they gently touch leaves, decorations and even other fish. This delicate exploration should not be confused with aggression, as it is a natural way of interacting with surroundings.

Silver Gouramis are most active during the day and at dusk. You may notice that they periodically retreat to plant thickets or hidden corners to rest. Their temperament and moderate size make them excellent centerpiece fish in medium and large community tanks, where they can be observed from different angles without causing stress to smaller inhabitants.

Recommended aquarium size and aquascaping

A single Silver Gourami can technically live in a smaller tank, but from the perspective of animal welfare and natural behavior, it is far better to provide a spacious environment. For a pair or trio, a minimum aquarium size of 80–100 liters is recommended, while for a small group it is wise to choose 120 liters or more. A longer tank with significant horizontal space allows the fish to establish territories and swim freely.

MB Store offers a wide range of aquariums in various sizes, enabling aquarists to adjust the setup to the planned stock and interior design. When planning a tank for Silver Gouramis, pay special attention to the layout. The background and sides can be planted more densely with tall, stem plants, while the central area remains partially open for swimming. Floating vegetation such as Salvinia or Amazon frogbit provides shaded areas, in which gouramis feel especially comfortable.

Hardscape elements, such as natural driftwood and stones, serve as visual barriers and help break up lines of sight between males. This reduces potential aggression and contributes to greater stability in the group. At the same time, such structures enrich the environment and provide attractive vantage points from which fish can observe the room.

The substrate should be chosen according to the overall concept. Darker sand or fine gravel accentuates the subtle shimmer of Silver Gouramis and creates a more natural atmosphere. The addition of leaf litter (where compatible with other inhabitants) can slightly lower pH and release beneficial substances, evoking the conditions of Southeast Asian habitats. However, it is important not to overdo the amount of organic matter so as not to destabilize water parameters.

Proper filtration is essential. Although Silver Gouramis tolerate slightly lower oxygen levels thanks to their labyrinth organ, they still require clean, stable water. MB Store offers efficient filters suited to different tank sizes, including internal, external and hang‑on‑back models. Flow should not be too strong; they prefer gentle currents that do not constantly disturb the surface or force the fish to struggle while swimming.

Water parameters, lighting and temperature

Silver Gouramis are relatively tolerant fish, which makes them attractive even for less experienced aquarists. Nevertheless, stable and appropriate water parameters remain the foundation of health and vitality. The recommended temperature range is 24–28°C, with around 26°C being an excellent compromise for mixed community tanks. Sudden temperature fluctuations should be avoided, as they can weaken the immune system and increase susceptibility to disease.

The pH range tolerated by these gouramis is broad, roughly between 6.0 and 7.8. For long term comfort, slightly acidic to neutral water is optimal, such as pH 6.5–7.2. General hardness (GH) may be from soft to medium hard, around 5–15°dGH. If local tap water significantly exceeds these values, it is worth considering blending it with reverse osmosis water and monitoring parameters using appropriate test kits.

Lighting should be moderate and adapted to plant species chosen for the aquarium. Silver Gouramis appreciate areas of shade created by floating plants or overhanging leaves. Strong, direct lighting across the entire surface can cause them to appear shy and spend more time hidden. Creating a balance of more brightly lit and darker zones allows natural behavior and attractive display of both fish and plants.

Because these fish breathe air using the labyrinth organ, special attention must be paid to the air above the water surface. It should be warm and humid, especially for young specimens. A tightly fitting cover glass or lid helps maintain appropriate conditions, while also preventing jumping. When cold air enters directly above the warm water surface, fish may experience respiratory issues over time.

Regular partial water changes are crucial for maintaining stable chemistry. A weekly change of 20–30% is usually sufficient in a well filtered tank with moderate stocking. MB Store supplies water conditioners and other accessories that make water preparation easy and safe, removing chlorine and binding heavy metals that may be harmful to delicate aquarium inhabitants.

Feeding and nutrition for optimal health

In their natural environment, Silver Gouramis feed on small invertebrates, insect larvae, crustaceans and plant matter. In an aquarium they readily accept a wide variety of foods, which greatly simplifies daily care. A well balanced diet contributes to vivid coloration, strong immunity and successful breeding, while also reducing stress.

High quality granules or flakes designed for omnivorous tropical fish can form the basis of their menu. The food should be of an appropriate size so that gouramis can easily ingest it. Supplementing with live and frozen foods, such as bloodworms, daphnia, brine shrimp or mosquito larvae, stimulates natural hunting instincts and supports proper development. Occasional addition of vegetable components, such as spirulina based products, also benefits digestion.

Feeding frequency depends on age and overall stocking. Adult Silver Gouramis can be fed two to three times a day with small portions that are consumed within a few minutes. Overfeeding leads to deterioration of water quality and promotes obesity, which may shorten the lifespan of the fish. It is better to provide smaller but diverse meals than large monotypic servings.

If the aquarium houses multiple species, ensure that all fish have access to food. Silver Gouramis usually feed in the middle and surface areas, while many catfish and loaches prefer the bottom region. Using slow sinking foods or specialized tablets for bottom dwellers prevents competition and keeps the community peaceful.

MB Store offers a broad selection of food brands for tropical fish, including products dedicated to labyrinth species. By choosing proven feeds, aquarists gain confidence that all necessary vitamins, minerals and amino acids are present, which inevitably affects resilience, reproductive success and general well being of Silver Gouramis.

Breeding Silver Gourami in the home aquarium

Breeding Silver Gouramis is a fascinating experience and often achievable for intermediate aquarists who provide a dedicated tank and follow several rules. This species is a bubble nest builder; the male constructs a floating nest at the surface, using air bubbles coated with mucus, often incorporating plant fragments.

To encourage spawning, a separate aquarium of about 40–60 liters is recommended, filled with shallow water of 15–20 cm depth. Soft, slightly acidic water and a temperature of 27–28°C are ideal. A layer of floating plants helps the male stabilize his nest. Only gentle filtration, such as a sponge filter, should be employed so as not to disturb bubble structures or suck in fry.

Before moving fish to the breeding tank, the selected pair should be conditioned with rich, protein based foods. The female’s abdomen will become visibly rounded with mature eggs. After introduction, the male will begin to build the nest and display courtship behavior: flaring fins, circling and gently embracing the female beneath the nest. Spawning occurs in several embraces, during which eggs are released and immediately fertilized.

The male collects the sinking eggs in his mouth and carefully places them in the bubble nest. After spawning is complete, the female should be removed to prevent potential harassment, as the male takes full responsibility for guarding and maintaining the nest. Within 24–36 hours, the eggs hatch, and several days later the fry become free swimming, at which point the male should also be removed.

Initial feeding of fry requires microscopic foods, such as infusoria or commercial liquid fry preparations. As they grow, newly hatched brine shrimp and finely powdered dry feeds can be offered. Maintaining excellent water quality and stable temperature is vital during this period, because young gouramis are sensitive to sudden changes. A carefully managed breeding project offers a unique window into the natural behavior of this species and can provide a healthy, captive bred population for future aquariums.

Health, common diseases and long term care

With proper care, Silver Gouramis can live 4–6 years, and sometimes longer. Many health issues can be avoided by preventing stress, providing high quality water and proper nutrition. Newly purchased fish should, whenever possible, be placed in a quarantine tank for observation before introduction into the main aquarium. This reduces the risk of transmitting parasites or infectious diseases to an established community.

One of the most commonly observed problems is ich, a parasitic disease characterized by small white spots on the body and fins. Prompt identification and treatment with appropriate medications are essential for successful recovery. Fungal infections and bacterial fin rot may also occur, often as a result of mechanical injuries or poor water conditions.

Because Silver Gouramis rely partially on the labyrinth organ, chronic exposure to very cold or dry air above the water surface can lead to respiratory disorders. Maintaining a closed lid and a small layer of warm air above the water line is particularly important, especially in colder climates or during winter months. Avoid sudden drafts or placing the aquarium near open windows.

Regular observation is the best diagnostic tool. Changes in color, clamped fins, lethargy, or refusal to eat may signal health issues or unsuitable environmental conditions. Testing water parameters, performing partial changes and adjusting feeding often resolve minor problems before they become serious. MB Store can support aquarists with a full range of medications, conditioners and maintenance accessories that help keep fish healthy over the long term.

Equipment and accessories useful for Silver Gourami keepers

An attractive and stable environment for Silver Gouramis requires not only an appropriate tank, but also reliable technical equipment. MB Store provides a comprehensive selection of filters, heaters, lighting systems and decorations, making it easy to configure a system matched to your home conditions and level of experience.

A good heater with an accurate thermostat is essential for maintaining the chosen temperature. Sudden drops, especially at night, are dangerous for tropical fish. A thermometer placed in a visible spot allows quick visual verification that conditions are stable. For filtration, models with adjustable output are recommended, enabling you to fine tune water movement to the preferences of gouramis and other inhabitants.

Appropriate lighting supports plant growth and enhances the natural colors of fish. Modern LED fixtures are energy efficient and often allow adjustment of intensity and spectrum. This makes it possible to set up zones of varying brightness in one tank, from more strongly lit regions for demanding plants to shaded corners cherished by Silver Gouramis.

An often overlooked accessory is the aquarium cover or lid. In addition to protecting the labyrinth organ by stabilizing the air above the water, it prevents evaporation and reduces the risk of fish jumping out. MB Store offers covers tailored to many tank formats, as well as custom solutions for more demanding layouts or open style aquaria that require additional safety measures.

Finally, care accessories such as siphons, algae scrapers, buckets used exclusively for aquarium work and high quality water conditioners are small investments that significantly facilitate regular maintenance. Thanks to them, water changes become quick and safe, and the aquarium remains a stable, thriving ecosystem in which Silver Gouramis feel secure.
