Fix Zole – Metronidazole Fish Antibiotics

Targeted Treatment for Protozoan & Anaerobic Infections

Fix Zole (Metronidazole) supports aquarists in managing internal and external infections linked to protozoa (e.g., Hexamita) and anaerobic bacteria. Common use cases include hole-in-the-head, intestinal parasites, fin/tail issues secondary to protozoal infection, and certain internal bacterial problems. For best results, confirm a protozoan/bacterial cause and use a hospital tank when possible.

Why Choose Fix Zole

Protozoan focus: Useful against Hexamita/Spironucleus and related intestinal issues in ornamental fish.
Anaerobic coverage: Targets certain anaerobic bacterial infections.
Flexible dosing: 250 mg & 500 mg tablets make mg/gal calculations straightforward in hospital tanks.
Aquarium-focused: Formulated for ornamental fish; follow label directions to protect biofilters and livestock.

Best-Practice Guidance

Confirm the cause: Metronidazole treats protozoan/anaerobic issues—won’t resolve parasites like ich trophonts once encysted or purely fungal problems.
Hospital tank: Remove carbon/UV if directed; maintain aeration and stable temperature; monitor appetite and feces.
Complete the course: Dose at the specified interval/duration—don’t stop early.
Water quality: Perform partial water changes per label; monitor ammonia and nitrite.
After treatment: Restore filtration media; consider a bacterial supplement to restabilize the system.

FAQs

250 mg vs 500 mg?
Choose the strength that simplifies mg-per-gallon dosing for your tank volume; many aquarists keep both sizes for flexibility.

Display tank or quarantine?
Quarantine is recommended to protect beneficial bacteria and invertebrates and to control dosage precisely.

How fast will I see results?
Improvement often appears within 24–72 hours, but finish the full course to reduce relapse risk.

Mixing medications?
Avoid combining antibiotics/antiprotozoals unless an aquatic professional advises it.
