A large, heavily-built labyrinth fish famous for its 'kissing' behavior. This kissing is actually a form of territorial sparring, mostly between males asserting dominance. They are specialized filter-feeders and grazers that use their raspy lips to scrape algae. Because they grow surprisingly large (up to 10-12 inches) and are prone to eating live plants, they require spacious aquariums and specific diets.

Kissing Gourami Varieties
Each variety inherits the species defaults above. Only differences are highlighted.
Pink (Standard Adult)
The most widely available commercial morph. It is leucistic, lacking the dark pigments of the wild type, presenting as a uniform pinkish-white. Can be highly territorial with other Kissing Gouramis as they reach adulthood.
Differs in 1 trait from base species
Also known as: Pink Kissing Gourami, Standard Pink
Green / Wild Type (Adult)
The natural wild coloration, featuring a silver-green body with darker horizontal stripes and opaque fins. Less common in the trade but identical in care to the pink morph.
Differs in 1 trait from base species
Also known as: Green Kissing Gourami, Wild Type
Balloon Morph
Selectively bred for a shortened, 'balloon-like' spine. This drastically alters their body shape, making them more susceptible to swim bladder and digestive issues. They stay shorter in length but are extremely dense.
Differs in 4 traits from base species
Also known as: Balloon Kissing Gourami, Dwarf Kissing Gourami
Juvenile (Grow-out)
Typical size sold in pet stores (1.5 - 2 inches). While they can temporarily live in smaller community tanks, they are rapidly growing, heavy-eating fish that will quickly require a permanent large setup.
Differs in 6 traits from base species
Also known as: Baby Kissing Gourami, Small
Kissing Gourami Care Guide Summary
The Kissing Gourami, scientifically known as Helostoma temminckii, belongs to the Anabantoids family group. Adults reach a maximum size of approximately 25 cm and have a compressed body shape with a moderate growth rate. Classified as semi-aggressive, this species primarily occupies the surface and mid-level zones of the aquarium and produces a high level of biological waste.
To thrive, the Kissing Gourami requires a freshwater only aquarium with a minimum volume of 280 litres and a tank length of at least 120 cm. Water temperature should be maintained between 22°C and 30°C, with a pH range of 6–8 and a general hardness of 4–20 dGH. A low water flow is preferred.
The Kissing Gourami is a rewarding species to keep, provided its core environmental needs are met. This species is available in 4 varieties: Pink (Standard Adult), Green / Wild Type (Adult), Balloon Morph, and Juvenile (Grow-out). Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.
Kissing Gourami Habitat Setup
When setting up an aquarium for the Kissing Gourami, a low water flow best suits their natural preferences. Because this species occupies the surface and mid-level zones, the aquarium layout should prioritise adequate surface area with floating cover to make them feel secure near the waterline and open swimming space in the centre of the tank for free movement. Useful additions include an established tank with natural algae growth, as they depend on it as a primary food source. Keepers should note that live planted layouts may be difficult to maintain, as this species tends to uproot or consume vegetation.
Kissing Gourami Compatibility Notes
Classified as semi-aggressive, the Kissing Gourami is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, conspecific aggression can be intense, especially in smaller tanks and territorial behaviour may cause issues if hiding spots or floor space are limited. Selecting tankmates that favour different water layers from the surface and mid-level zones can help reduce competition and territorial overlap.

Fish Similar to Kissing Gourami
Moonlight Gourami
Trichogaster microlepis
A gracefully sloping, large labyrinth fish characterized by its beautiful, iridescent silvery sheen and exceptionally long, thread-like ventral fins (feelers). While peaceful and somewhat timid, they are notorious for nibbling on soft-leaved and fine aquarium plants. They require access to the surface to breathe atmospheric air.
Giant Gourami
Osphronemus goramy
The Giant Gourami is a massive, highly intelligent anabantoid that behaves more like a wet pet than a typical community fish. They grow extremely large and have voracious appetites, often completely consuming any live plants in their tank. Due to their immense adult size and extreme bioload, they require massive aquariums and robust filtration.
Banded Gourami
Trichogaster fasciata
The Banded Gourami is a robust and hardy labyrinth fish known for its striking diagonal stripes. Considerably larger than the Dwarf Gourami, they are active swimmers but generally peaceful in community settings. They require access to the water's surface to breathe atmospheric air. Males can be highly territorial toward each other.
Dwarf Gourami
Trichogaster lalius
A peaceful to semi-aggressive labyrinth fish native to South Asia. Famous for their brilliant metallic blue and red stripes. While generally suitable for community tanks, males are territorial toward each other and similar-looking fish. They are sensitive to water quality and prone to Iridovirus if stressed. Requires access to the surface to breathe.
Pearl Gourami
Trichopodus leerii
Widely considered the most beautiful and peaceful of the large Gouramis. They feature a 'mosaic' of iridescent spots and a distinct black line running through the eye. Unlike their aggressive cousins (the Three-Spot Gourami), Pearls are generally gentle giants, though males can be territorial towards one another. They are thermophilic (love heat) and require floating plants to feel secure.
Betta (Siamese Fighting Fish)
Betta splendens
The Siamese Fighting Fish is an aquarium icon known for its labyrinth organ (allowing air breathing) and vivid colors. While hardy, they require heated, filtered water (24-30°C). Males are solitary and fiercely territorial. Females are generally less ornate but can be kept in 'sororities' with strict precautions (minimum 5 females in 75L+).
