Fix Zole (Metronidazole) – 250 mg & 500 mg Antibiotics for Fish & Birds

Fix Zole (Metronidazole) 250 mg & 500 mg is a powerful OTC fish antibiotic often referred to as “fish zole.” It effectively combats common aquarium diseases like hexamitiasis, spironucleus, and hole-in-the-head, helping fish regain their appetite and vitality. Meanwhile, metronidazole for birds addresses respiratory or GI infections caused by protozoa (e.g., trichomoniasis), making Fix Zole a versatile solution for multi-pet owners.

Whether you’re tackling stubborn flagellate outbreaks in freshwater or saltwater tanks, or managing avian parasites, Fix Zole provides broad-spectrum protection when used correctly. If you need a no-prescription approach (where legally allowed) to safeguard both fish and birds, Fix Zole is your one-stop antibiotic.

    Handles protozoan infections such as hexamitiasis, spironucleus, and trichomoniasis.

  • 250 mg or 500 mg Tablets
    Choose the dosage strength that matches your pet’s size and infection severity.

  • No Rx Hassle
    Easily available OTC, reducing vet prescription steps.

Wondering How to Use Metronidazole 250/500 mg?

  1. Check Dosage Guidelines

    • 250 mg suits mild/moderate infections; 500 mg targets more severe outbreaks.

  2. Administer Safely

    • Fish: Pre-dissolve in tank water or a separate tub for even distribution.

    • Birds: Mix crushed tablets into feed or water, ensuring full consumption.

  3. Stay Consistent

    • Continue daily for 5–10 days (or as a vet advises). Stopping early can cause relapse.

  4. Observe Recovery

    • Look for normalized appetite, improved activity, and reduced symptoms. If no progress, consult a pro.
