The Kissing Gourami (Helostoma temminckii) is a unique and popular freshwater fish known for its distinctive behavior and appearance. Here's some information about Kissing Gouramis:

Kissing Gouramis have an elongated, laterally compressed body with a rounded head and a large mouth. They can grow up to 12 inches (30 cm) in length, making them relatively large aquarium fish. They have a mottled or marbled coloration with shades of green, brown, or gray. One of their most recognizable features is their protruding lips, which can be extended to "kiss" or lock with other Kissing Gouramis during courtship or territorial disputes.

Kissing Gouramis are native to Southeast Asia, specifically found in Thailand, Malaysia, Indonesia, and Borneo. They inhabit slow-moving or stagnant freshwater environments, such as lakes, ponds, and rivers with dense vegetation. They prefer warm water temperatures ranging from 75°F to 82°F (24°C to 28°C) and appreciate water with a neutral pH and moderate hardness.

Kissing Gouramis are generally peaceful fish, but they can become territorial, especially during breeding or when kept in cramped quarters. They get their name from their behavior of "kissing" or locking lips with each other, which is a display of dominance or courtship. They have a unique ability to produce loud croaking or grunting sounds by grinding their pharyngeal teeth together.

Kissing Gouramis require a spacious aquarium with plenty of swimming space. A minimum tank size of 55 gallons (208 liters) is recommended for a single adult, with larger tanks being preferable for a group or community setup. They appreciate the presence of hiding spots and dense vegetation, including floating plants. Regular water changes and maintenance of good water quality are important for their health.

Diet: Kissing Gouramis are omnivorous and have a varied diet. They are primarily herbivorous and will readily consume plant matter, including algae and aquatic vegetation. However, they also consume small invertebrates and other meaty foods. In captivity, they can be fed high-quality flake or pellet food designed for herbivorous fish, as well as supplemented with blanched vegetables, spirulina-based foods, and occasional live or frozen foods.

Tankmates: Kissing Gouramis can coexist with other peaceful fish species in a community aquarium. However, their territorial behavior and large size should be taken into consideration when choosing tankmates. Avoid keeping them with small or delicate fish that may be intimidated or harassed by their size or behavior. Compatible tankmates include similar-sized peaceful fish like other gouramis, larger tetras, barbs, and rasboras.

Breeding: Breeding Kissing Gouramis in captivity is challenging and rarely occurs. They are bubble nest builders, and breeding requires specific conditions, including warm water, floating plants, and compatible pairs. The male builds a nest at the water's surface, entices the female to spawn, and guards the nest and fry. However, successful breeding is relatively uncommon in home aquariums.

Kissing Gouramis are popular among aquarium enthusiasts for their unique behavior and appearance. With proper care, a suitable environment, and compatible tankmates, they can be an interesting addition to a larger community aquarium.
