The moonlight gourami (Trichopodus microlepis) is a beautiful freshwater fish. It's also called the moonbeam gourami. This fish comes from Indochina, a region in Southeast Asia. It's known for being peaceful. Many people like to keep it in their aquariums at home.
Moonlight gouramis belong to a special group of fish called labyrinth fish. They have a unique organ that helps them breathe air. This allows them to live in water with low oxygen.

About the Moonlight Gourami
An adult moonlight gourami can grow up to about 13 centimeters (5 inches) long. This measurement is called SL, which means "standard length." It measures from the tip of the nose to the base of the tail fin.
These fish have a shiny, silver color. They often have a soft green tint, like the gentle glow of moonlight. Their head slopes inward, which helps tell them apart from other types of gourami fish.
Telling Males from Females
It's easy to tell male and female moonlight gouramis apart. Males have orange or red pelvic fins. These fins are long and thread-like. Their dorsal fin (the fin on their back) is also long and ends in a point.
Female moonlight gouramis have pelvic fins that are clear or yellow. Their dorsal fin is shorter and more rounded. When it's time to lay eggs, the male's orange pelvic fins become a much brighter red.
Where They Live
The moonlight gourami naturally lives in the Mekong River and Chao Phraya basins. These rivers flow through countries like Cambodia and Vietnam. They have also been found in the Mekong basin in Thailand.
Sometimes, these fish escape from fish farms. This has happened in Colombia, where they now live in the wild.
Their Home Environment
Moonlight gouramis prefer quiet places. They live in ponds and swamps. You can find them in shallow water that moves slowly or stands still. These areas usually have lots of water plants. They are also common in the floodplains of the lower Mekong River.
What They Eat
Moonlight gouramis are not picky eaters. They enjoy a diet of small creatures. Their favorite foods include insects and tiny crustaceans. They also eat zooplankton, which are very small animals that float in the water.
How They Breathe Air
Moonlight gouramis are special because they can breathe air. Like all labyrinth fish, they have a unique organ. This organ works like a lung. It lets them take in air directly from above the water.
You might see them swim to the surface and gulp air. This ability helps them survive in water with very little oxygen. They can even stay alive out of water for several hours if they stay moist!
Reproduction and Life Cycle
Moonlight gouramis lay eggs, which means they are oviparous. They build special "bubble nests" to protect their eggs and young.
Building a Bubble Nest
The male moonlight gourami starts the process. He carefully builds a bubble nest on the water's surface. These nests usually don't have many plants mixed in. The bubbles might even float around freely.
Courtship and Spawning
Once the nest is ready, the male tries to attract a female. He performs a special "courtship dance" under the bubble nest. When the female is ready, the male wraps his body around her.
While they are wrapped together, the male turns the female onto her back. This makes her release her eggs. A female can lay up to 2,000 eggs at one time! As the eggs float up, the male fertilizes them. He then guides them into the safety of the bubble nest.
The eggs will stay in the bubble nest. They usually hatch after about two to three days.
