Tank Size: Provide a tank of at least 10 gallons for a school of Harlequin Rasboras. They are social and should be kept in groups of six or more. Water Parameters: Maintain stable conditions with a temperature range of 73-82°F (23-28°C), a pH level of 6.0-7.0, and soft to moderately hard water. Filtration: Use efficient filtration to ensure good water quality and oxygenation. Regular water changes help maintain optimal conditions. Aquascape: Create an environment with live plants, driftwood, and open swimming areas. Harlequin Rasboras appreciate a well-decorated tank with hiding spots among plants. Tank Mates: They are peaceful and can be kept with other small, non-aggressive community fish that share similar water parameters. Diet: Harlequin Rasboras are omnivores and accept a diet that includes high-quality flakes, pellets, and live or frozen foods like brine shrimp, daphnia, and micro worms. A varied diet is important.
