Origin/Distribution

The popular Kissing Gourami, or ‘Kisser’, originates from the Indonesian island of Java, and is also found in Borneo, Cambodia, Malaysia, Thailand and Vietnam. It is commonly cultivated in the southern Indochina region as a food fish. These days virtually all specimens sold in the USA are commercially bred in Florida. Thailand and Signapore also commercially breed this species for the aquarium trade as well as for food consumption.

The common name, Kissing Gourami, is derived from what appears to be kissing; however scientists still aren’t sure of the true purpose of the behavior. It’s believed to be a harmless challenging behavior, which generally occurs between two males. This conjecture is supported by the fact that aging seems to diminish the need to challenge one another. With age the desire for mating territories diminishes.

Description

There are three colors variations of this fish; a pink or flesh colored form, a silver-green form often referred to as the Green Kisser, and a mottled or piebald variety. The pink variation does not occur as frequently in nature, and is the result of a reduction in pigmentation known as leucism. This trait has been selectively bred for the aquarium trade, due to the color preference by owners.

The green species is the naturally occurring coloration. It has has a dark bar bordering the dorsal and anal fins. The pink and green have at times been described as separate species, but they are all a single species. A mottled or piebald variation is also sometimes seen for sale, however it is less popular than the pink variety.

A mutation that has been bred for the aquarium trade is short and round, giving it a balloon-like appearance. This mutated strain is not as hardy as the naturally occurring varieties, and has a shorter lifespan.

Both sexes of Kissing Gourami look almost identical; from their oval shape to their thick fleshy lips. What you can’t see are the rows of fine teeth on the inside surface of those lips, which are used to graze on algae and vegetable matter. Another unseen structure in these fish is the labyrinth organ, which is present in all labyrinth fishes.

This organ enables them to take oxygen from the air, thus permitting them to survive in waters with low oxygen levels. In fact, the gills of labyrinth fishes are usually not capable of obtaining enough oxygen from the water to survive. Therefore, they must satisfy some of their oxygen requirement by gulping air at the surface of the water. That is why it is essential to provide them with access to the water surface.

Tankmates

Kissing Gouramis have been known to be quarrelsome with some species of fish, and should not be kept with smaller fish. Although they can be be kept in a community tank with medium to large size fish, owners should observe them closely to ensure they are not bullying other fish. Kissing Gouramis will sometimes rasp the sides of other fish, stripping them of their slime coat and potentially damaging their skin. If this occurs it is wise to separate the fish.

Habitat/Care

In nature Kissers are usually found in slow moving heavily vegetated ponds or marshes. They are a hardy fish that will tolerate a range of water conditions. However, they need a lot of space, with access to the surface, warm water and plenty of vegetation. Because they are fond of plant matter in their diet, use artificial plants or sturdy live plants such as Java Fern or Java Moss. Tender plants are likely to be eaten down to the stem.

In nature they grow to a size of a foot or more, but in captivity they generally remain about half that size. However, even a small Kisser will grow too large for an aquarium under 30 gallons, and should not be kept in the popular mini-tanks. With good care it is not unusual for these fish to live well over a decade.

Diet

Kissers accept a variety of foods, including; flake, frozen, freeze-dried, and small live foods, such as Tubifex and Brine Shrimp. They also will accept any kind of vegetable matter, and should be provided with plenty of Spirulina-based foods, as well as fresh vegetables when possible.

Periodically providing fresh romaine lettuce, cooked zucchini or peas, will keep your Kissers in optimal health. Take care when providing fresh vegetables, as uneaten portions will quickly foul the water.

Sexual Differences

It is almost impossible to determine the sex of these fish until they spawn. At that time the body of the female becomes round as it fills with eggs.

Breeding

Potential breeders should be conditioned with live foods, and provided with a large tank with soft warm water (80 F). Unlike other Labyrinth fish, Kissers do not build elaborate bubble nests, although the male may blow bubbles randomly at the surface.

Spawning begins by circling, progressing to nudging and dancing, followed by intense beating of tails, and finally kissing. Eventually the male wraps his body around the female, turning her upside down. The female will release hundreds or even thousands of eggs, which are fertilized by the male as they rise to the surface.

If floating plants or lettuce are placed on the surface before spawning, the eggs will adhere to them and the fry can feast upon the infusoria that grows on the vegetation. The parent fish should be removed following spawning, as they may eat their own young.

Eggs will hatch in approximately one day, and in another two days the fry will be free swimming. They can be fed very fine flake foods or small live foods such as freshly hatched brine shrimp.
