Hikari Metro+ is a powdered treatment designed to help address hole-in-the-head disease and lateral line erosion in pond, freshwater, and marine fish. This metronidazole-based formula works systemically to target infected areas and support recovery.
The treatment can be applied directly to aquarium or pond water as a bath treatment, or incorporated into medicated food for internal infections. An included slime coat replacer helps support external healing during treatment.

- After 24 hours, complete another 30% water change before the next dose.
- Continue treatment for 5-7 days or until mortalities cease.
- If no improvement is observed within 6 days, discontinue treatment and consider other options.
Oral Treatment:
- Prepare medicated feed using gelatin-based or dry food methods.
- Feed at least twice daily the amount fish consume within 5 minutes.
- Remove uneaten food to maintain water quality.
- Continue feeding for at least 3 days after symptoms disappear.
- Do not use medicated food older than 10 days.
Warning: Do not use with permanganate-based treatments. Avoid sulfur or sulfinite-based water conditioners unless confirmed compatible.
PRO TIP
Before dosing, calculate the true water volume of your aquarium by measuring length x width x height and dividing by 238 to determine gallons, then subtract the volume displaced by substrate, rocks, and decorations to prevent overdosing.
