Pearl Gouramis are compatible with many peaceful species. They do well with tetras, rasboras, and small catfish. Tank mates should be non aggressive and calm.
They can be kept singly or in small groups. Providing enough space reduces territorial behavior. Males may display mild dominance during breeding periods.
Avoid fin nippers and very active fish. Aggressive species can cause stress and hiding. Compatibility improves in larger aquariums.
Bottom dwellers like Corydoras are suitable companions. Community tanks work best with similar sized fish. Stable groups promote natural behavior.
Pearl Gouramis prefer calm aquariums with gentle filtration. They thrive in well planted tanks with floating vegetation. Plants help diffuse light and provide a sense of security.
Water parameters should be stable and slightly acidic to neutral. Regular maintenance keeps them healthy and stress free. They are sensitive to sudden changes in conditions.
The aquarium should include open swimming areas. Decor such as driftwood and roots is beneficial. A covered tank prevents heat loss and air temperature issues.
They use a labyrinth organ to breathe atmospheric air. Warm, humid air above the water surface is important. This supports proper respiratory function.
Pearl Gouramis are omnivores with a broad diet. They accept flakes, pellets, and small sinking foods. High quality prepared foods form a good base diet.
Live and frozen foods improve conditioning. Brine shrimp and daphnia are readily accepted. These foods enhance color and vitality.
Occasional vegetable matter is beneficial. Blanched spinach or spirulina flakes can be offered. This helps maintain digestive health.
Feed small portions once or twice daily. Remove uneaten food to avoid water quality issues. Consistency is key for long term health.
Pearl Gouramis are bubble nest builders. Males construct nests using saliva and plant material. Floating plants are important for nest support.
During breeding, males become more colorful. They actively court females beneath the nest. Spawning occurs in calm, warm water.
Eggs float into the bubble nest after spawning. The male guards the nest and eggs. Females should be removed after spawning.
Fry hatch within a few days. Infusoria and fine foods are needed initially. Gradual growth requires stable conditions.
