Harlequin Rasbora Aquarium Care Guide

Keeping Harlequin Rasbora in an aquarium requires the right conditions.

Aquarium Information

• Care level: beginner
• Temperament: peaceful
• Diet: omnivore
• Minimum tank size: 10 gallons (38 liters) for a small school
• Compatibility: Excellent community fish, compatible with other peaceful, similarly sized species such as other small rasboras, tetras, dwarf cichlids, corydoras, and small Loricariids.
• Special requirements: Requires a well-planted aquarium with subdued lighting and dark substrate to bring out their best coloration. They are schooling fish and should be kept in groups of at least 6-10 individuals to reduce stress and encourage natural behavior. Peat filtration or botanicals (e.g., catappa leaves) can help maintain the preferred acidic, soft water conditions.
