Hikari Metro+™ Fish Medication

Hikari Metro+™ is a professional-strength powdered fish medication formulated with metronidazole to treat a variety of protozoan and internal infections in freshwater, saltwater, and pond fish. Designed for both bath treatments and medicated food, Metro+™ provides a versatile and highly effective solution for some of the most challenging fish diseases, including Hole-in-the-Head (HITH) and Head and Lateral Line Erosion (HLLE).

Unlike many metronidazole medications, Metro+™ also contains a proprietary slime coat replacer that helps support healing of damaged skin and scales while treatment is underway. Whether you're caring for discus, cichlids, tangs, angelfish, or other freshwater and marine species, Metro+™ delivers targeted treatment while remaining gentle on fish when used as directed.
