Kissing Gourami (Helostoma temminckii) lives in freshwater across Southeast Asia. It feeds on algae and plants. Its conservation status is Least Concern.
Fascinating facts about the Kissing Gourami
- A single kiss can last seconds, but it isn't romance, it's a ritualized fight. Two fish meet head-on, jaws fully extended, and press mouths together for a few seconds. This "kissing" behaviour is described as and serves to establish dominance among conspecifics.
- When it comes to feeding, the kissing gourami has an additional joint. An and that H. temminckii is the only species known to use this articulation for that purpose. This mechanical advantage lets the fish thrive on benthic algae in slow-moving, vegetated waters.
- Reproduction is a race against time. In Thailand, spawning runs from May to October, "at the beginning of the rainy season" when adults migrate to shallow lagoons or flooded forests. A female drops an average of 1,000 spherical buoyant eggs, which hatch after just one day, and the fry become free-swimming two days later. The species reaches sexual maturity at three to five years.
- Size matters for both predators and hobbyists. In the wild, kissing gouramis grow up to a maximum of 30 cm (12 in) in total length, while in aquariums they can reach 30-40 cm (12-15.5 in). Their large, rounded pectoral fins and elongated soft rays give them a distinctive silhouette, and the species lacks any outward sexual dimorphism, making sex identification. Their substantial size and territorial nature explain why they quickly outgrow small tanks and can bully similarly sized tank mates.
- While the average lifespan in captivity and the wild is listed as five to seven years, individuals have been recorded living "in excess of 25 years". This potential for a quarter-century life means owners are making a long-term commitment.
