Broad-Spectrum Treatment for Bacterial & Parasitic Infections
Fish Zole 250mg is a trusted aquarium medication containing Metronidazole—effective against a wide range of internal and external fish infections. This powerful treatment addresses protozoan parasites and anaerobic bacterial diseases like Hexamita, Ich (white spot), gill flukes, and hole-in-the-head. Whether in freshwater or marine environments, Fish Zole supports a faster recovery and a healthier aquatic system.
What does Fish Zole treat? Fish Zole is used to treat protozoan parasites and anaerobic bacterial infections, including Hexamita, Ich, Costia, gill flukes, and internal bacterial conditions.
How does Metronidazole work? It interferes with DNA synthesis in parasites and anaerobic bacteria, stopping them from replicating and eliminating infection at its root.
Is it safe for all fish? Yes, when dosed properly. However, sensitive fish should be monitored. Invertebrates should be removed during treatment.
Can Fish Zole be used for prevention? No. This is a treatment—not a preventative—and should only be used when symptoms are present or confirmed.
Can I use it during quarantine? Yes. It is ideal for treating new fish showing signs of internal or external infections during the quarantine process.
How soon will results appear? Most users report visible improvement within 3 to 5 days. Fish typically regain color, appetite, and activity.
Will Fish Zole harm the tank’s good bacteria? No. It selectively targets anaerobic bacteria and protozoa, preserving your biofilter.
Can I combine it with other meds? Only under veterinary guidance. Unsupervised mixing of medications can reduce effectiveness or create toxic combinations.
How do I dispose of leftover capsules? Follow local guidelines. Do not flush or dispose of in water systems.
How should I store the product? Keep in a sealed container in a dry place at 59°F–86°F, away from moisture and direct sunlight.
