Species: H. temminckii
Binomial Name: Helostoma temminckii
These guys have a very distinctive mouth. Their fish lips are thick and fleshy, lined with little horny teeth, hence they became popular for the fish's peculiar kissing behavior. As the each Kisser approaches each other their plump lips lock together for a brief time then release. Although scientist are studying these fish to determine the reason for their behavior, it is thought that it is a social test of strength and/or status. So actually, they are not kissing at all!
In the wild, they can grow to a maximum length of 12 inches (30 centimeters), however, they will only grow to the area. So if the Kisses are held in captivatiy they may not get larger than 5 inches. They are tropical, freshwater fish that are actually surface breathers. They grow very rapidly, and are extremely territorial. Kissing gouramis will bully, chase and torment other fish causing significant stress on other tank mates.
Kissing fish have no external sexual dimorphism. It is incredibly difficult to distinguish them sexually. The females are usually heavier than the males. They are found in two different colorations. There is a green coloration, that originated in Thailand, and a pink, rose, or orange coloration that originated in Java. There is also a dwarf or balloon, pink coloration which is a mutated strain of the pink gourami. 'Balloons' are named for their smaller and rounder bodies.
These fish are omnivores and feed on both plant and animal matter to maintain a balanced diet.
