Pearl Gourami (Trichogaster leerii)

Pearl Gourami Care Guide with Aquarium Size Requirement:

1. Species Overview:

• The Pearl Gourami (Trichopodus leerii) is a captivating and peaceful freshwater fish native to Southeast Asia. Known for its vibrant coloration and distinctive pearl-like scales, it is a popular choice for community aquariums.

2. Aquarium Size:

• Provide a tank with a minimum size of 30 gallons for a single Pearl Gourami. If keeping a pair or a small group, consider a larger tank of 50 gallons or more.
• Ensure the tank has ample swimming space and hiding spots created by plants and decorations.

3. Water Parameters:

• Maintain a stable water temperature between 77°F to 82°F (25°C to 28°C).
• Aim for a slightly acidic to neutral pH level, ideally between 6.0 and 7.5.
• Keep the water hardness in the soft to moderate range, around 5 to 12 dGH.

4. Size of the Fish:

• Pearl Gouramis can grow to a size of about 4 to 5 inches (10 to 12.7 centimeters).

5. Tank Decor:

• Set up the aquarium with live plants, floating vegetation, and driftwood to mimic the natural habitat of the Pearl Gourami. Provide open spaces for swimming.
• They appreciate dimmed lighting, so use floating plants to create shaded areas.

6. Diet:

• Pearl Gouramis are omnivores. Feed them a varied diet that includes high-quality flakes, pellets, and live or frozen foods like brine shrimp and bloodworms.
• Offer a mix of protein-rich and plant-based foods to ensure a balanced diet.

7. Behavior:

• Pearl Gouramis are peaceful and can be kept in community tanks with other non-aggressive species. They may show territorial behavior during breeding.
• They are labyrinth fish, meaning they can breathe air from the surface, so provide access to the water's surface.

8. Tank Mates:

• Choose tank mates that are compatible in size and temperament. Suitable companions include other peaceful community fish such as tetras, rasboras, and dwarf cichlids.
• Avoid keeping them with aggressive or fin-nipping species.

9. Tank Maintenance:

• Conduct regular water changes of 20-30% every two weeks to maintain good water quality.
• Use a reliable filtration system suitable for the tank size.

10. Breeding:

• If breeding is desired, provide a separate breeding tank with dense vegetation and floating plants. Pearl Gouramis are bubble nest builders, and the male creates a nest at the water's surface.
• Once eggs are laid and fertilized, remove the adults to prevent them from eating the fry.

By following these care guidelines and providing an appropriately sized and well-maintained aquarium, Pearl Gouramis can thrive, displaying their graceful movements and adding beauty to a community tank.
