Tank Size: Provide a tank of at least 20 gallons for a single Blue Gourami. Larger tanks are better for multiple Gouramis or a community setup. Water Parameters: Maintain stable conditions with a temperature range of 72-82°F (22-28°C), a pH level of 6.0-7.5, and slightly soft to moderately hard water. Filtration: Effective filtration is essential to maintain water quality and oxygenation. Aquascape: Include live plants, floating vegetation, and hiding spots. Blue Gouramis appreciate a well-decorated tank with subdued lighting. Tank Mates: They are generally peaceful but can be territorial during breeding. Choose tankmates carefully, avoiding fin-nipping fish. Diet: Blue Gouramis are omnivores, accepting high-quality flakes, pellets, live or frozen foods, and occasional vegetable matter.
