Overview
Helostoma temminckii is a species in the family Helostomatidae. Named for its distinctive lip-locking behavior between individuals, which is actually a form of sparring rather than affection. Can grow quite large at 25+ cm. Available in pink and green color forms. An efficient algae grazer that uses its specialized lips to rasp surfaces.
Taxonomy
- Family: Helostomatidae
- Genus: Helostoma
- Scientific name: Helostoma temminckii
- Other names: Kisser Fish
- Origin: Southeast Asia, Thailand, Java
Habitat
Native to Thailand and the Malay Archipelago, with introduced populations across Southeast Asia. Inhabits slow and standing waters with dense vegetation. The "kissing" behaviour is a mutual mouth-pushing display; the species filter-feeds and grazes algae and microorganisms. The sole member of the family Helostomatidae.

- Temperature: 22-28 °C
- pH: 6-8
- GH: 5-20 °dGH
- Water flow: low
- Adult size: 15-30 cm
- Lifespan: 5-7 years
- Difficulty: intermediate
Diet
Classified as omnivore. Recommended feeding frequency: 2x daily. In captivity, offer a varied diet appropriate to the species — quality prepared foods supplemented with frozen or live items of suitable size.
Compatibility
- Temperament: semi-aggressive
- Swimming level: middle
- Compatible tank mates: Large Barbs, Bristlenose Pleco, Large Catfish
- Avoid with: Small Fish, Delicate Plants, Slow Fish
Breeding
- Breeding strategy: egg-scatterer
- Breeding difficulty: advanced
Kissing Gourami (Helostoma temminckii) Breeding Guide
Overview
Helostoma temminckii is native to mainland Southeast Asia and the Greater Sundas, reaching up to 30 cm. Unlike most labyrinth fish in the trade it is an open-water egg scatterer rather than a bubble nester, and it does not build a nest or care for its young. Despite a 5-7 year average lifespan, it can exceed 25 years in captivity, and sexual maturity is reached at three to five years of age.
Sexing
Reliable external sexing is not documented for this species; both sexes show the same kissing or sparring behaviour, in which individuals meet mouths and push each other through the water. This rasping action is used by males to challenge the dominance of conspecifics and is not a courtship display.
Breeding Setup
Because spawning takes place under cover of floating vegetation, the breeding tank should include floating plants. In captivity, lettuce leaves placed on the water surface can serve as a spawning medium, providing the overhead cover the fish prefer.
Spawning Behavior & Trigger
Kissing gouramis are open-water egg scatterers, with spawning initiated by the female beneath floating vegetation. In nature spawning occurs from May to October in Thailand, at the beginning of the rainy season. Females release approximately 1000 eggs per spawning event.
Egg & Fry Care
The eggs are spherical, smooth and buoyant, each carrying a drop of oil that increases buoyancy, so fertilised eggs float to the surface. The adults do not guard them. Eggs hatch after about one day and the fry are free-swimming two days thereafter.
Common Challenges
The large adult size demands a correspondingly large spawning tank, and the late sexual maturity of three to five years means breeders must be fully grown before any attempt. Because there is no parental care, eggs and fry are vulnerable, so the floating cover and a separate rearing approach support survival.
