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.

Why Choose Hikari Metro+?

  • Proven Active Ingredient: Contains metronidazole, widely used to treat microbial infections.
  • Systemic Treatment: Works internally to target affected areas.
  • Flexible Application: Can be used as a bath treatment or incorporated into medicated fish food.
  • Supports Recovery: Slime coat replacer helps aid external healing.
  • Broad Fish Compatibility: Suitable for freshwater, marine, and ornamental pond fish.
  • Extremely Safe: Designed for safe use when directions are followed.

Dosing Instructions

Bath Treatment:

  • Perform a minimum 30% water change before the first treatment and before each daily retreatment.
  • Use 1 capful (~10 g) per 20 gallons (76 L) of water daily to achieve approximately 5 mg/L of metronidazole.
  • 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.
