The species is native to Southeast Asia (Myanmar, Vietnam, Thailand, Malaysia, and Indonesia) but, has been introduced in different continents (Africa and South America). In general, gouramis occur in low oxygen, plant-choked, low mineral content, tea-colored/black-water areas. Furthermore, the water has a high amount of tannin due to the decomposition of leaves and wood. As a result of the human expansion, the original habitat of gouramis has altered and are found in pig farms and rice paddies (Colisa sp.), etc. In addition to the degradation of gouramis’ habitat, many species are in danger of extinction.
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
Pearl gouramis are an excellent choice for beginners because of their hardiness. It’s best to keep the species in a ratio of one male with two females as males can be territorial with the same species as well as with other species. It’s best to keep them in an only-species tank. In community tanks, the three-spot gourami is compatible with sturdy fish such as barbs and large characins.
Because of the natural habitat of three-spot gouramis should be kept in soft acidic water. A pH between 6.0-7.0, with a temperature between 26-30 Celsius, and hardness 50mg/l, suits the species.
Three-spot gouramis need big aquariums as they get stress easily and males are territorial. An aquarium with 120 liters of water is suitable for a pair of 2-3 gouramis. Plants are necessary as they provide shelter for stressed fish and their offspring, especially floating plants. Furthermore, the surface air should have a similar temperature of the water for the prevention of losses. Cover the aquarium to maintain a similar temperature above and under the water.
Three-spot gouramis are omnivorous and can eat prepared food and small live-foods such as brine shrimp, white worms, bloodworms, etc. In nature, their diet consists of small invertebrates, algae, insects’ larvae, hydra, e.t.c

For the survival of the young, the species is best to spawn in a breeding tank than an only-species tank with many individuals. For the reproduction of the species, an aquarium with dense floating plants and water depth of 10 cm suits for breeding three-spot gouramis. Like almost every fish, another key for breeding gouramis is diet. Besides prepared food, feed the pearl gouramis with a variety of high-quality foods such as live foods. Last, Remove the female after she releases the eggs and when the young are swimming-free, remove the male too.
