Fish Zole Forte (Metronidazole) is a high-concentration formulation of metronidazole designed to treat severe or persistent internal parasitic and protozoan infections in aquarium fish, or for treating larger fish. As part of our commitment to providing comprehensive fish care solutions, we offer Fish Zole Forte within our Thomas Labs Fish Antibiotics category. For a broader selection of fish health products, please also see our Fish Medication category. At Thomas Labs Pet, we strive to provide quality medications for a variety of fish health needs.

Metronidazole is an antibiotic and antiprotozoal medication effective against certain anaerobic bacteria and protozoans. Fish Zole Forte contains a higher concentration of metronidazole than standard Fish Zole, making it a stronger treatment option. This is beneficial for infections that haven’t responded to standard metronidazole or when treating larger fish that require a higher dose. It’s often used to treat Hexamita, which causes “Hole-in-the-Head” disease (lateral line erosion).

Common Fish Diseases Treated with Metronidazole (Fish Zole Forte):

  • Severe cases of Hexamita (“Hole-in-the-Head” disease/lateral line erosion)
  • Stubborn or persistent Spironucleus infections
  • Other protozoan infections requiring a higher dose of metronidazole
  • Some anaerobic bacterial infections requiring a higher dose

How to Use Fish Zole Forte (Metronidazole):

  • Dosage: Follow the instructions on the product label carefully. Dosage is based on the volume of water in your aquarium. Because this is a higher concentration formula, accurate dosing is especially critical.
  • Water Changes: Perform a partial water change (25-50%) before starting treatment and between doses.
  • Treatment Duration: Complete the full course of treatment as recommended on the product label, even if symptoms improve.
  • Quarantine Tank: It is highly recommended to treat infected fish in a separate quarantine tank to avoid disrupting the biological filter in your main aquarium.

Important Considerations:

  • Accurate Diagnosis: Ensure the fish’s illness is indeed parasitic or protozoan before using metronidazole. It will not be effective against most bacterial or viral infections (except for specific anaerobic bacteria).
  • Monitor Water Parameters: Metronidazole can affect the beneficial bacteria in your filter. Monitor ammonia, nitrite, and nitrate levels closely during treatment.
  • Consult a Veterinarian: If you are unsure about the diagnosis or treatment, consult a qualified aquatic veterinarian.
