Are you looking to add some sparkle and elegance to your aquarium? Look no further than the Pearl Gourami! This beautiful fish, also known as the Lace Gourami, is a popular choice among fishkeepers for its stunning appearance and peaceful nature. Native to Southeast Asia, these fish are commonly found in slow-moving waters, such as rice paddies and swamps. In this care guide, we'll cover everything you need to know to create a healthy and happy home for your Pearl Gourami, from tank setup to breeding and beyond. So, let's dive in!
Origins and History
The Pearl Gourami (Trichogaster leeri) is native to Southeast Asia, where it can be found in the slow-moving waters of Thailand, Malaysia, Sumatra, and Borneo. These fish are commonly found in shallow, densely vegetated areas such as rice paddies, swamps, and slow-moving streams.
Pearl Gouramis were first introduced to the aquarium hobby in the early 1900s, and since then, they have become a popular and widely kept species. In the wild, Pearl Gouramis are threatened by habitat loss and pollution, but their popularity in the aquarium trade has led to successful captive breeding programs. Today, Pearl Gouramis are readily available in pet stores and online, making them a great choice for both beginner and experienced fishkeepers.
Species
The Pearl Gourami (Trichogaster leeri) is a species of labyrinth fish, which means that they possess a labyrinth organ. This organ allows them to breathe atmospheric air in addition to oxygen dissolved in water, which enables them to survive in low-oxygen environments.
Pearl Gouramis are a relatively large species, with males growing up to 5 inches (12.7 cm) in length and females reaching up to 4 inches (10.2 cm) in length. They have a distinctive appearance, with a pearlescent white body and iridescent blue and green markings. Males have longer dorsal fins and more vibrant colors than females.
In addition to their stunning appearance, Pearl Gouramis are known for their peaceful temperament and are often kept in community aquariums with other peaceful species. However, they can become territorial during breeding, so it's important to provide plenty of hiding spots and visual barriers in the aquarium.

Tank setup
When it comes to setting up an aquarium for Pearl Gouramis, it's important to provide a spacious and well-decorated environment that mimics their natural habitat. A tank size of at least 30 gallons (113 liters) is recommended for a pair of Pearl Gouramis, with an additional 10 gallons (38 liters) for each additional fish.
Pearl Gouramis prefer heavily planted aquariums with plenty of hiding spots and visual barriers. Live plants such as java fern, anubias, and Amazon sword plants provide both cover and food sources for these fish. Decorations such as driftwood, rocks, and caves can also provide hiding spots and territorial boundaries.
A dimly lit aquarium with subdued lighting is recommended for Pearl Gouramis, as they prefer low light levels. A dark substrate, such as sand or gravel, can help to enhance the fish's colors and create a natural-looking environment.
It's also important to maintain good water quality in the aquarium. Regular water changes and the use of a high-quality filter are crucial for keeping the tank clean and healthy for your fish.
Water parameters
Maintaining proper water parameters is crucial for the health and well-being of your Pearl Gouramis. These fish prefer soft, slightly acidic water with a pH range of 6.0-7.5 and a temperature range of 75-82°F (24-28°C).
Water hardness should be kept between 5-15 dGH, with a lower level preferred. If your tap water is too hard, consider using a reverse osmosis (RO) system or a water softener to lower the hardness.
It's also important to maintain good water quality by performing regular water changes and monitoring ammonia, nitrite, and nitrate levels. Ammonia and nitrite should be at 0 ppm, while nitrate should be kept below 20 ppm.
In addition, Pearl Gouramis are sensitive to high levels of dissolved organic matter and should be kept in a well-filtered aquarium with good water flow. A high-quality canister or hang-on-back filter is recommended for a Pearl Gourami aquarium.
Feeding
Pearl Gouramis are omnivorous and will eat a variety of foods in the wild. In the aquarium, it's important to provide a balanced diet that includes both plant and animal-based foods.
A high-quality pellet or flake food can form the basis of your Pearl Gourami's diet, supplemented with frozen or live foods such as brine shrimp, bloodworms, and daphnia. Vegetables such as blanched spinach or zucchini can also be offered as a treat.
It's important to avoid overfeeding your Pearl Gouramis, as they are prone to obesity and related health issues. Offer only as much food as your fish can consume in 2-3 minutes, and feed no more than twice a day.
In addition, it's a good idea to vary your Pearl Gourami's diet to ensure that they are getting all the necessary nutrients. A varied diet can also help to prevent boredom and encourage natural feeding behaviors.
Behavior and Compatibility
Pearl Gouramis are peaceful fish that can be kept in community aquariums with other peaceful species. However, they can become territorial during breeding and may exhibit aggression towards other fish of the same species or similar appearance. It's recommended to keep only one male Pearl Gourami per tank, with multiple females or a mix of males and females.
In addition, Pearl Gouramis are labyrinth fish and need access to the surface of the water to breathe atmospheric air. They may jump out of the water if they feel stressed or oxygen-deprived, so it's important to keep the aquarium well-covered to prevent escape.
Pearl Gouramis are active swimmers and appreciate a spacious aquarium with plenty of swimming room. They are also known to be surface-oriented fish and will spend a lot of time near the water's surface. Providing floating plants, such as water lettuce or water hyacinth, can provide both cover and an additional food source for these fish.
Finally, it's important to note that Pearl Gouramis are sensitive to changes in water parameters and can be stressed by sudden changes. It's important to acclimate new fish slowly to the aquarium and to maintain stable water conditions.
Diseases and Treatment
Like all aquarium fish, Pearl Gouramis are susceptible to a variety of diseases. The most common ailments affecting Pearl Gouramis include bacterial infections, fungal infections, parasites, and viral diseases.
Signs of illness in Pearl Gouramis include lethargy, loss of appetite, abnormal swimming behaviors, discoloration, and visible lesions or growths. If you suspect that your fish is sick, it's important to quarantine the affected fish and seek treatment immediately to prevent the spread of disease to other fish in the aquarium.
Treatment for diseases in Pearl Gouramis varies depending on the specific ailment. Bacterial infections can be treated with antibiotics, while fungal infections may respond to antifungal medication. Parasitic infections can be treated with medications such as praziquantel or metronidazole.
Prevention is key when it comes to keeping your Pearl Gouramis healthy. Maintaining good water quality, feeding a varied and balanced diet, and avoiding overstocking the aquarium can all help to prevent stress and disease. It's also a good idea to quarantine new fish before introducing them to the main aquarium to prevent the introduction of disease.
Breeding
Pearl Gouramis are relatively easy to breed in the aquarium, and breeding behavior can be triggered by providing the right conditions. To encourage breeding, it's important to provide the fish with a spacious aquarium, a varied and nutritious diet, and a peaceful environment.
During breeding, male Pearl Gouramis will develop bright colors and vertical stripes, while females will become noticeably plumper. Males will also build bubble nests at the water's surface, which can range from a few bubbles to a large cluster.
After spawning, the male Pearl Gourami will fertilize the eggs and guard the nest until the fry hatch. It's important to remove any other fish from the breeding tank, as they may eat the eggs or fry.
Once the fry have hatched, they will be tiny and may require special care. Feeding them infusoria or liquid fry food can help to ensure their survival. As the fry grow, they can be gradually transitioned to more substantial foods such as baby brine shrimp or finely crushed flake food.
Breeding Pearl Gouramis can be a rewarding experience for aquarists. However, it's important to remember that breeding can be stressful for the fish, and not all fish may be interested in breeding. If you are interested in breeding Pearl Gouramis, it's recommended to do additional research and consult with experienced breeders for more information.
