Trichogaster lalius, commonly known as the Dwarf Gourami, is a small, colorful freshwater fish native to South Asia. They thrive in slow-moving waters like ponds, rice fields, and streams. Known for their vibrant red and blue stripes, these peaceful fish exhibit labyrinth organ breathing, allowing them to gulp air.

Trichogaster lalius, commonly known as the Dwarf Gourami, is native to South Asia. It is primarily found in the northern regions of India, including the states of Assam, Bihar, and West Bengal, as well as in Bangladesh. The species is also reported in parts of Pakistan and Nepal.

The Dwarf Gourami typically inhabits slow-moving waters such as ponds, lakes, and rivers with abundant vegetation. The environmental conditions of these habitats include warm temperatures ranging from 22°C to 28°C (72°F to 82°F), a neutral to slightly acidic pH level typically between 6.0 and 7.5, and soft to moderately hard water. The presence of aquatic plants is crucial, as these provide both shelter and foraging opportunities.

Trichogaster lalius occupies the ecological niche of a small omnivorous fish, feeding on a variety of food sources available in its habitat. This includes small insects, larvae, and plant matter. The species is adapted to survive in environments with low oxygen levels, utilizing a specialized labyrinth organ that allows it to breathe atmospheric air.
