Pink Kissing Gourami (Helostoma temminckii) — 2cm

Overview

The Pink Kissing Gourami, scientifically known as Helostoma temminckii, is one of the most recognizable and characterful tropical fish uk species available to aquarists. Famous for its distinctive "kissing" behavior and soft pink coloration, this hardy Southeast Asian native brings personality and charm to larger community aquariums. The common name refers to the fish's habit of pressing their thick, fleshy lips together—a behavior that appears affectionate but is actually a form of social interaction, dominance testing, or territorial display. Growing to an impressive 30cm in well-maintained aquariums, the kisser fish requires a spacious setup of at least 400 litres and proves itself a robust, long-lived companion suitable for aquarists ready to provide appropriate space and care. Available for sale UK through aquatic retailers, juveniles are commonly offered, but prospective owners must plan for their substantial adult size.

Appearance

The pink kissing gourami displays a uniform pale pink to silvery-pink coloration across its entire body, with no distinct patterns or markings. The body is deep and laterally compressed, with a slightly arched back. The most distinctive feature is the terminal, protrusible mouth with thick, fleshy lips equipped with small teeth-like denticles used for scraping algae. The fins are semi-transparent with a pinkish tint. Juveniles appear similar to adults, just smaller and slightly paler. There is also a green/wild-type color variant with grey-green coloration, though the pink form is far more common in the aquarium trade. The eyes are relatively small, and the overall appearance is somewhat plain compared to more colorful species, but the unique mouth structure and behavior make this fish instantly recognizable.

Natural Habitat

Kissing gouramis inhabit slow-moving rivers, ponds, canals, and flooded areas across mainland Southeast Asia, including Thailand, Cambodia, Laos, Vietnam, Malaysia, and Indonesia. They're also established in introduced populations in other tropical regions. In the wild, these fish graze extensively on algae growing on submerged surfaces, supplementing this with small invertebrates and plant matter. Natural habitats range from clear, well-oxygenated streams to murky, oxygen-poor floodplains—the labyrinth organ allows them to breathe atmospheric air, providing tolerance for varied conditions. Aquarium setups should offer warm, clean water with ample swimming space and surfaces for grazing.

Aquarium Setup

A suitable aquarium for adult pink kissing fish must prioritize space. A minimum of 400 litres is essential, with 600+ litres preferred for keeping multiple individuals or a tropical community fish setup. These are active, constantly-swimming fish that need room to roam. Use smooth gravel or sand substrate, and incorporate driftwood, rocks, and robust artificial plants (live plants may be grazed or uprooted). Provide excellent filtration with strong biological capacity—these are messy fish that produce substantial waste. Ensure good surface agitation for oxygen exchange, though the labyrinth organ allows tolerance for less-than-ideal oxygen levels. A secure lid is recommended, as gouramis can jump when startled or during disputes.

Feeding

The diet should be primarily vegetable-based to reflect the species' natural grazing behavior. Offer spirulina flakes, algae wafers, blanched vegetables (zucchini, cucumber, spinach), and quality herbivore pellets. Supplement with protein-rich foods like bloodworms, brine shrimp, and daphnia 2-3 times weekly. Feed multiple small portions throughout the day if possible, or 2-3 times daily. These fish are enthusiastic eaters and prone to obesity if overfed protein-rich foods. Allow natural algae growth on tank surfaces for grazing—many keepers rotate rocks or decor from a sunlit location to provide algae-covered surfaces. The constant grazing behavior helps control algae naturally while fulfilling nutritional needs.

Behaviour

Despite their peaceful-sounding common name, kissing gouramis are semi-aggressive and quite bold. The famous "kissing" behavior occurs between individuals testing dominance or defending territory—mouths lock and push against each other, sometimes for several seconds. This is rarely harmful but indicates social tension. Males are territorial with each other, particularly in smaller aquariums. These fish are constantly active, swimming throughout all levels of the tank and investigating every surface for food. They're curious and interactive, often approaching the glass when people pass. The combination of active swimming, grazing behavior, and occasional "kissing" displays makes them entertaining and engaging tank inhabitants.

Tank Mates

Suitable companions must be similarly sized, robust, and capable of holding their own. Large peaceful community fish, other substantial gouramis, large barbs, rainbowfish, and large tetras work well. Avoid small fish that will be bullied or outcompeted for food. Also avoid slow-moving, long-finned species vulnerable to nipping, as well as timid fish that will be stressed by the kissing gourami's bold personality. Very aggressive fish should also be excluded, as kissing gouramis, while bold, are not equipped to defend against serious aggression. Shrimp and small invertebrates will be eaten. In a properly sized aquarium with appropriate tankmates, kissing gouramis integrate well into peaceful tropical fish communities despite their size.

Breeding

Breeding is possible in very large, well-maintained aquariums with soft to moderately hard water. Males construct bubble nests at the surface among floating plants, then court females with displays and gentle nudging. Spawning occurs beneath the nest, with eggs floating to the surface. Parents do not provide further care and may eat eggs or fry, so removal or heavy planting is necessary for fry survival. Fry are tiny and require infusoria or liquid fry food initially, graduating to newly hatched brine shrimp as they grow. Breeding kissing gouramis is uncommon in home aquaria due to space requirements and the challenge of raising large numbers of fry, but it's achievable for dedicated breeders with appropriate facilities.

Special Considerations

The kissing gourami lifespan can exceed 15 years with proper care, making this a long-term commitment. Adult size and activity level demand substantial tank space—attempting to keep them in undersized aquariums leads to stunted growth, aggression, and shortened lifespan. While hardy and tolerant of a range of water conditions, maintain stable parameters and excellent water quality through regular large water changes. The labyrinth organ requires access to atmospheric air—never seal the tank completely, and keep water level a few centimeters below the lid to ensure adequate air space. Monitor for common gourami diseases like bacterial infections or parasites, treating promptly if issues arise.
