Mosaic Gourami

Generally, gouramis have a long, flattened body with extended and filamentous ventral fins that are used as tactile organs to obtain physical information about objects. Furthermore, gouramis can use ventral fins for orientation in dark, muddy water habitats. Trichogaster leeri have a greyish body with remarkable white spots all over the body as well as a long black line from the head to the start of the caudal fin. Pearl gouramis have an average size of 4 inches (10 cm). Gouramis, like the rest of the Anabantoidei fish, can breathe atmospheric air. This ability occurs in Anabantoidei fish due to an organ located closed to the branchial apparatus, the labyrinth. The species have an average of 4 years lifespan.
The species have sexual dimorphism that is easier to recognize after the age of 7 months. Males have long pointed dorsal fins while females have short rounded dorsal fins. Breeding males have an orange-reddish coloration on the ventral side with filamentous extensions on the anal and dorsal fins.
