Kissing Gourami – Helostoma temminckii

Kissing Gourami, known scientifically as Helostoma temminckii, is one of those aquarium fish that instantly attract attention and spark curiosity. Its distinctive “kissing” behavior, impressive size, and shimmering body make it a unique addition to larger community tanks. In this article, we will explore its natural habitat, behavior, requirements in the aquarium, and compatibility with other fish. We will also show how, with proper equipment from MB Store, you can create optimal conditions for these unusual gouramis and enjoy their fascinating life for many years.

Origin, appearance and the famous “kiss” of Helostoma temminckii

The Kissing Gourami comes from Southeast Asia, mainly from Thailand, Indonesia and Cambodia. In the wild it inhabits slow-flowing rivers, backwaters, rice fields and densely vegetated ponds. These waters are usually warm, slightly acidic to neutral, rich in vegetation and natural hiding places. Such conditions are a useful model when planning an aquarium that is meant to become a comfortable home for this species.

Adult Helostoma temminckii can reach 20–30 cm in length, which makes it a relatively large labyrinth fish. Its body is high, laterally flattened, often silvery, slightly greenish or pinkish depending on the variety and lighting used in the aquarium. Some cultivated forms have more intense pink or almost creamy coloration that beautifully reflects light. The fish’s lips are thick, clearly protruding, covered with small horn-like structures that allow it to scrape algae and biofilm from surfaces.

The characteristic “kissing” behavior, which gave the fish its popular name, consists in bringing the lips of two individuals together and pressing them against each other. Contrary to romantic associations, this is usually a form of territorial interaction or a way of establishing dominance, especially between males. The fish do not hurt each other in a dramatic way, but such contests can be intense, so it is important to observe the group and provide sufficient space. The same mouth structure is also used to scrape algae from aquarium glass, roots and stones, thanks to which Kissing Gourami can support the overall appearance of the tank, although it should not be treated as a professional “cleaning crew”.

Helostoma temminckii, like other labyrinth fish, has a special organ that allows it to breathe atmospheric air. This feature means that the fish must have free access to the water surface and that the aquarium must be covered, but not sealed completely, to ensure good gas exchange. Observant aquarists will notice how the Kissing Gourami periodically swims up to the surface to take a “sip” of air, which is natural and necessary behavior.

Aquarium requirements: tank size, water parameters and decor

Due to its size and temperament, Kissing Gourami is not a fish for small aquariums. For a single specimen, an absolute minimum is about 150 liters, but for a group a tank of 250–300 liters or more is strongly recommended. The longer the aquarium, the better, because these fish like to swim and need space to avoid constant conflicts. MB Store offers a wide selection of aquariums of various capacities and dimensions, which makes it easier to choose a tank that suits both the needs of this species and the available space at home or in the office.

Optimal water temperature for Helostoma temminckii is 24–28°C. The fish feel good in slightly acidic to neutral water, with a pH of about 6.5–7.5. Water hardness can be low to medium, which corresponds to typical conditions in many home aquariums. The key is stability: sudden changes in temperature or pH are not advisable. Good filtration is essential, because large fish produce more waste, which leads to a rapid increase in nitrates. Strong current is not necessary; a moderate, evenly distributed flow is sufficient.

As for the interior arrangement of the tank, it is worth ensuring a balance between open swimming areas and densely vegetated fragments. Kissing Gourami appreciates thickets of plants, where it can hide or rest. At the same time, it often nibbles on delicate leaves, so it is better to choose more durable species, such as Java fern, Anubias or some strong stem plants. Decor elements like roots and stones not only diversify the visual aspect, but also facilitate the natural scraping of algae, which is part of the Kissing Gourami’s daily activity.

Since these fish breathe atmospheric air, the space between the water surface and the cover should not be too cold. A large temperature difference between water and air may lead to infections of the labyrinth organ. A cover glass or cover with ventilation holes is a very good solution. MB Store provides suitable aquarium covers, lighting systems and accessories that help maintain stable microclimate above the water surface and within the whole tank.

Regular partial water changes are particularly important in tanks with large fish. It is recommended to replace 20–30% of the water weekly, or more often if the aquarium is densely stocked. Using tap water conditioner and proper maintenance tools available in MB Store makes this routine easier and safer, both for the aquarist and the fish.

Diet, feeding and health of Kissing Gourami

Helostoma temminckii is an omnivore with a clear tendency to consume plant material. In nature it feeds on algae, plant fragments, microorganisms and small invertebrates. In the aquarium, a varied diet is the foundation of good health, intense colors and natural behavior. A well-balanced base can be good quality granules or flakes for omnivorous and herbivorous fish, enriched with plant components such as spirulina.

To complement the diet, it is worth regularly serving blanched vegetables: zucchini slices, spinach, lettuce or cucumber. This not only supports the digestive system, but also helps satisfy the natural need to graze and nibble. Occasional portions of frozen or live food (bloodworms, brine shrimp, daphnia) are beneficial, but should not dominate the menu; too much protein can lead to obesity and digestive problems. The Kissing Gourami is quite greedy, so feeding should be controlled and divided into 2–3 small portions a day instead of one large one.

One of the health aspects to monitor is the condition of the fins and body. Visible damage, dull coloration or apathetic behavior may signal stress, inappropriate water parameters or infection. Good water quality and a balanced diet are the best natural “medicine”. Another important element is observing interactions in the group. Permanent strong aggression, constant chasing and “kisses” that escalate into injuries may require separating individuals or rearranging the decor, adding more hiding places and visual barriers.

Due to their labyrinth organ, Kissing Gouramis are sensitive to low oxygen content in water only to a limited extent, but this does not mean that aeration can be neglected. Proper filtration with surface movement ensures efficient gas exchange and helps maintain high oxygen levels. MB Store provides filters, air pumps and accessories that make it easier to create a stable environment conducive to fish health, while also supporting the clarity and aesthetics of the aquarium.

Preventive measures include quarantine of new fish and plants, especially in larger, established tanks. Introducing pathogens with new inhabitants is one of the most common causes of disease outbreaks. A separate small aquarium for quarantine, equipped with a sponge filter and heater, is a cheap and effective form of protection, and all necessary equipment can be easily obtained at MB Store.

Behavior, temperament and suitable tank mates

Although Kissing Gourami is often considered peaceful, its temperament is more complex. Young fish are usually quite calm and shy, but with age they become more territorial. Males in particular can demonstrate dominance through the characteristic “kissing” behavior. These contests usually do not end with serious injuries, but in smaller tanks can become a source of permanent stress. Therefore, appropriate space and a properly designed interior are crucial.

Helostoma temminckii is best kept in groups of several individuals in large aquariums, where each fish has the opportunity to mark its area and avoid constant contact with dominant neighbors. In smaller setups, keeping a single specimen is sometimes better than forcing a pair or trio into too tight space. Observation is key: if one fish is constantly chased, it may be necessary to modify the stocking or add more decorations that break the line of sight.

When choosing tank mates, it is important to focus on fish of similar size and temperament. Good candidates include larger barbs, some medium and large tetras, rainbowfish, and other species of gourami that are not overly aggressive. Avoid very small fish such as neon tetras, as they might be treated as potential food in the long run. Fin-nippers, such as some aggressive barb species, are also not desirable, as they may attack the long fins of gouramis.

Cichlids may be possible companions only in sufficiently large tanks and after careful analysis of species and individual temperament. Peaceful or moderately territorial cichlids from similar water parameters might coexist, but it is always associated with some risk. On the other hand, calm bottom dwellers like Corydoras or certain loaches often get along well with Kissing Gourami, because they occupy another part of the water column and rarely enter into direct competition.

Helostoma temminckii is active during the day, frequently exploring the entire tank, cleaning surfaces from algae, checking plants and decorations. It can sometimes appear clumsy due to its size, especially among delicate stems and roots. Therefore it is worth using solidly rooted plants and stable elements that will not be easily moved. Well-chosen equipment and decor, available at MB Store, help create a visually attractive environment that also respects the behavior and needs of fish.

Setting up a Kissing Gourami tank with MB Store equipment

Planning an aquarium dedicated to Helostoma temminckii is an excellent opportunity to design a spacious, natural-looking tank. The first step is choosing a suitable aquarium. Considering the size and activity of these fish, it is advisable to choose a long tank of at least 250–300 liters for a group. MB Store offers a wide range of aquariums that meet these requirements, from classic rectangular models to modern sets with integrated cabinets and lighting.

Next comes filtration. Since Kissing Gouramis are large and produce substantial biological load, efficient filters are crucial. External canister filters work very well, providing large space for filter media and stable water parameters. It is worth choosing a device with adjustable output, which allows to fine-tune the flow strength to the preferences of the inhabitants. MB Store supplies both compact filters for smaller setups and advanced filtration systems for large show tanks.

Proper lighting supports not only plant growth, but also the coloration and behavior of fish. Kissing Gourami looks particularly attractive in slightly warm-toned light that emphasizes its silver-pink sheen. LED lighting with adjustable intensity and spectrum enables precise adaptation to the needs of the aquarium. It is also energy-efficient and durable. In MB Store you can find various lighting systems, from simple ready-made sets to programmable lamps controlled via applications or controllers.

Heating is another key element. Stable temperature in the range of 24–28°C is a condition for the well-being of tropical species. Reliable heaters with thermostats, preferably with a small reserve of power, guarantee that the aquarium will remain safe even during cooler periods. MB Store offers heaters of different power ratings, which facilitates matching them to the volume and dimensions of the tank.

Substrate and decor should not only look good, but also serve the fish. A fine or medium-grained substrate allows easy rooting of plants and does not injure fish that occasionally pick food from the bottom. Roots and stones create natural hiding places and surfaces overgrown with algae and biofilm, which Kissing Gourami willingly scrapes. MB Store provides a wide selection of decorations, including natural roots, rocks and artificial elements that are safe for aquatic life and easy to arrange.

An often underestimated aspect of aquarium planning is maintenance equipment: nets, scrapers, siphons, water conditioners and biological supplements. Regular cleaning of the bottom, glass and filter, combined with water changes, guarantees stable conditions. MB Store offers comprehensive sets of accessories that make these tasks more convenient and less time-consuming. Thanks to them, caring for a Kissing Gourami tank becomes a pleasure rather than a burden.

Breeding and advanced care of Helostoma temminckii

Breeding Kissing Gourami in home aquariums is not as common as with smaller labyrinth fish, but it is possible for experienced aquarists. In nature they build floating nests of foam and plant fragments, similar to Betta or some other gouramis. In captivity, successful breeding usually requires a separate, well-prepared tank with calm water surface, plenty of floating plants and very good water quality.

Conditioning the breeding pair involves rich feeding with high-quality food, including live and frozen items, as well as plant components. A slightly higher temperature and increased frequency of water changes can stimulate spawning. The male typically builds a foam nest near the surface, where the female lays eggs. After spawning, as with many labyrinth species, it is often recommended to remove the parents to prevent them from eating the eggs or larvae, although some individuals may show a degree of care.

Raising fry demands delicate feeding with infusoria, then freshly hatched brine shrimp and finely powdered dry foods. Water must be crystal clean, but at the same time changes should be small and gradual to avoid stressing the fry. Good biological filtration, gentle aeration and constant monitoring of parameters are key. Equipment, food for fry and necessary accessories for breeding projects are readily available through MB Store, which makes organizing such an undertaking much more accessible.

Beyond breeding, advanced care focuses on long-term monitoring of fish condition. Kissing Gourami can live 7–10 years or more in good conditions, which means that we take responsibility for a relatively long-lived resident. Over time some individuals may become less active or more susceptible to infections, so regular observation, quick response to alarming symptoms, and adaptation of food portions to metabolism changes at older age are important.

Helostoma temminckii is a fascinating species that can become a central point of a large, well-planned aquarium. Thanks to its size, unique appearance and behavior, it draws attention of everyone who looks at the tank. At the same time it requires responsible and informed care: sufficient space, stable parameters, balanced diet and appropriate company. With the help of high-quality aquarium sets and accessories offered by MB Store, many of these challenges become much easier to meet, allowing aquarists to focus on enjoying the beauty and uniqueness of this remarkable fish.

FAQ

Is Kissing Gourami suitable for beginners?
Kissing Gourami can be kept by a beginner, but only if the person understands that this is a large fish requiring a spacious aquarium and good filtration. It is not ideal for small starter tanks. If a novice aquarist is ready to invest in a larger setup and learn basics of water chemistry and maintenance, Helostoma temminckii can be an interesting and rewarding species.

Do Kissing Gouramis really kiss out of affection?
The “kiss” is mostly a territorial and dominance behavior, not a sign of affection. Two fish press their lips together to test strength and establish hierarchy, especially males. In a large tank this usually does not lead to serious injuries. However, constant intense “kissing” in a small aquarium may indicate stress or overcrowding and should prompt review of stocking and decor.

What is the minimum tank size for Kissing Gourami?
For a single Kissing Gourami, an absolute minimum is about 150 liters, but this is rather a compromise. For a group and for long-term keeping, it is better to plan a tank with volume of at least 250–300 liters. The aquarium should be long, with a large surface area. This provides room for swimming, creating territories and reducing aggression, which directly affects wellbeing of the fish.

Do Kissing Gouramis eat live plants?
Helostoma temminckii eagerly nibbles soft plants and young leaves, so not all species will survive in its aquarium. It is better to choose tougher plants such as Anubias, Java fern or some hardy stems. Supplementing diet with vegetables reduces pressure on plants, but does not eliminate it. Proper plant selection and regular feeding help to keep the aquarium both green and safe for the fish.

Can Kissing Gourami live with small fish?
In theory they can coexist with small fish, but this is not always safe. Young Kissing Gouramis usually ignore tiny tankmates, yet adults may start seeing them as potential prey. There is also risk of stress for small fish caused by the size and activity of larger neighbors. Therefore it is better to choose medium or larger species as companions, which reduces risk of accidental predation and conflicts.
