Fish Zole™ – Metronidazole 250 mg – 100 Tablets

Fish Zole™ provides metronidazole 250 mg tablets in a clearly identified 100-tablet bottle for expressly labeled ornamental and aquarium-fish applications.

```

Each tablet contains a labeled strength of 250 mg of metronidazole. The active ingredient, strength, tablet format, and package quantity are clearly displayed to help aquarium keepers verify the exact product before completing an order.

This larger 100-tablet package is offered separately from smaller Fish Zole package quantities and higher-strength Fish Zole Forte products. Customers should confirm the active ingredient, 250 mg strength, tablet format, and 100-count package before checkout.

With more than 16 years of experience serving aquarium keepers, FishFlexFishMox is committed to clear product information, dependable sourcing, careful United States order processing, and responsive customer support.

Fish Zole Product Details

  • Product name: Fish Zole™
  • Active ingredient: Metronidazole
  • Strength: 250 mg per tablet
  • Package quantity: 100 tablets
  • Product format: Tablets
  • Product category: Fish antibiotics
  • Intended application: Expressly labeled ornamental and aquarium fish
  • Current listed expiration: 08/2027
  • Shipping coverage: United States only

Always inspect and verify the complete physical product label before opening, handling, or using Fish Zole. Confirm the active ingredient, strength, tablet count, intended species, expiration date, lot information, storage requirements, cautions, and current supplier instructions.

Metronidazole 250 mg Per Tablet

Each Fish Zole tablet is identified as containing 250 mg of metronidazole.

The clearly displayed active ingredient and strength help distinguish this product from aquarium products containing different ingredients, strengths, physical formats, or package quantities.

Before placing an order, confirm:

  • That metronidazole is identified as the active ingredient;
  • That the strength is 250 mg per tablet;
  • That the selected package contains 100 tablets;
  • That the physical product format is tablets;
  • That the expressly labeled ornamental-fish application matches the physical label;
  • That the displayed price and package quantity are correct;
  • That the available expiration information meets your purchasing requirements; and
  • That all applicable warnings, cautions, and storage information have been reviewed.

Do not select an aquarium product based only on the Fish Zole name. Always verify the complete product title, active ingredient, strength, physical format, package count, and current physical label.

Large 100-Tablet Bottle

This listing includes one bottle containing 100 Fish Zole tablets.

The clearly identified 100-tablet package provides a larger-count option for customers seeking this specific active ingredient, strength, and tablet format.

Before completing checkout, confirm that the product page, cart, checkout page, and order confirmation display:

  • Fish Zole™;
  • Metronidazole 250 mg;
  • 100 Tablets;
  • Tablets as the physical product format;
  • One bottle unless another configuration is expressly stated;
  • The correct product price; and
  • The correct United States shipping destination.

The complete product title, selected product, cart, checkout page, order confirmation, and physical bottle determine the exact product included with the purchase.

Never rely only on a product photograph when confirming the strength, format, or package quantity. Product images may remain in use after a supplier updates part of the bottle, label, cap, safety seal, or packaging design.

250 mg Fish Zole vs. 500 mg Fish Zole Forte

Fish Zole and Fish Zole Forte are traditional product-family names associated with metronidazole-based ornamental-aquarium products.

  • Fish Zole: Commonly associated with metronidazole 250 mg products;
  • Fish Zole Forte: Commonly associated with metronidazole 500 mg products.

This product contains 250 mg of metronidazole per tablet. It should not be confused with a 500 mg Fish Zole Forte product.

A difference in strength is significant. Always confirm that the product page, cart, checkout page, order confirmation, and physical bottle all identify the intended 250 mg strength.

Products containing the same active ingredient but different strengths should not be treated as interchangeable.

Compare Fish Zole Package Options

Fish Zole metronidazole products may be available in several separately identified strengths, package quantities, and physical formats.

Available or previously offered configurations may include:

  • Fish Zole metronidazole 250 mg – 30 Tablets;
  • Fish Zole metronidazole 250 mg – 60 Tablets;
  • Fish Zole metronidazole 250 mg – 100 Tablets;
  • Fish Zole Forte metronidazole 500 mg – 30 Tablets;
  • Fish Zole Forte metronidazole 500 mg – 60 Tablets;
  • Fish Zole or Fish Zole Forte powder packets; and
  • Other clearly identified supplier-approved configurations.

This listing is specifically prepared for metronidazole 250 mg in a 100-tablet bottle.

Different product options may vary in price, strength, supplier, manufacturer, packaging, physical appearance, lot number, inventory batch, and expiration date.

Never use product details or instructions associated with another strength, format, manufacturer, or package quantity.

Understanding the Fish Zole Product Name

Fish Zole is the traditional product-family name used for certain metronidazole-based ornamental-aquarium products.

This product should be identified using the following essential specifications:

  • Product family: Fish Zole;
  • Active ingredient: Metronidazole;
  • Strength: 250 mg per tablet;
  • Physical format: Tablets;
  • Package quantity: 100 tablets; and
  • Intended application: Expressly labeled ornamental and aquarium fish.

The physical bottle may display Fish Zole, Fish Metronidazole, Metronidazole 250 mg, or another supplier-approved presentation.

A difference between the ingredient-focused website title and the product name displayed on the physical bottle does not necessarily indicate that an incorrect product was supplied.

The essential identifying details are the active ingredient, strength per tablet, tablet format, total package quantity, supplier information, expiration date, and expressly labeled species or application.

Fish Zole vs. Other Fish Products

Metronidazole is a separately identified active ingredient and should not be confused with other products in the FishFlexFishMox catalog.

  • Fish Zole: Metronidazole;
  • Fish Mox: Amoxicillin;
  • Fish Flex: Cephalexin;
  • Fish Doxy: Doxycycline;
  • Fish Flox: Ciprofloxacin;
  • Fish Pen: Penicillin;
  • Fish Flucon: Fluconazole;
  • Fish Min: Minocycline.

Products should not be treated as interchangeable merely because they are offered within the same aquarium-products category.

Always verify the exact active ingredient on the product page, cart, checkout record, order confirmation, and physical bottle.

Verify the Physical Product Label

The physical bottle and product label supplied with the order remain the final product-specific references for:

  • The complete product name;
  • The active ingredient;
  • The strength per tablet;
  • The tablet count;
  • The manufacturer, supplier, or distributor;
  • The expressly labeled species and application;
  • The lot or batch number;
  • The expiration date;
  • The storage requirements; and
  • All applicable warnings and cautions.

Review the complete physical packaging before opening, handling, or using the product.

Do not rely exclusively on an older product page, third-party description, search-engine summary, social-media post, or photograph associated with another Fish Zole strength, count, format, or supplier.

Current Listed Expiration: 08/2027

The current catalog-listed expiration date for Fish Zole is 08/2027.

Expiration dates may change when new supplier shipments or production batches are received. The expiration date printed on the physical bottle supplied with the order is the final product-specific expiration date.

Different strengths, formats, and package quantities may come from separate inventory batches and may therefore display different lot numbers, packaging details, label designs, or expiration dates.

A particular lot number, production batch, packaging design, supplier, or expiration date is not guaranteed unless expressly confirmed for the applicable order.

Customers requiring expiration confirmation before purchasing may contact us through our Contact Us page.

Product Label and Packaging

Fish Zole should arrive in its original, clearly labeled bottle or supplier-approved packaging.

The physical packaging may identify:

  • Fish Zole, Fish Metronidazole, or another approved product-family name;
  • Metronidazole as the active ingredient;
  • 250 mg as the strength per tablet;
  • 100 tablets as the package quantity;
  • The expressly labeled ornamental-fish application;
  • The manufacturer, supplier, or distributor;
  • The lot or batch number;
  • The expiration date;
  • Storage information; and
  • Important warnings and cautions.

Manufacturers and suppliers may update packaging details without prior notice, including:

  • Bottle shape, size, or color;
  • Cap or safety-seal design;
  • Tablet appearance;
  • Label layout;
  • Typography;
  • Logo or branding placement;
  • Supplier information;
  • Lot-number placement; and
  • Expiration-date placement.

The product received may look different from an older photograph while still matching the essential active ingredient, strength, tablet count, physical format, supplier information, and intended application displayed on this page.

Inspect Fish Zole After Delivery

Before opening or using Fish Zole, inspect the shipping package, bottle, physical label, safety seal, tablets, package quantity, lot information, and expiration date.

Do not use the product if:

  • The shipping package or product bottle is substantially damaged;
  • The bottle is broken, open, or leaking;
  • A required safety seal appears missing or compromised;
  • The physical product label is missing or unreadable;
  • Metronidazole is not identified as the active ingredient;
  • The strength is not 250 mg per tablet;
  • The physical contents do not match the tablet format;
  • The package quantity does not match the 100-tablet listing;
  • The expiration date has passed;
  • The tablets appear damaged, contaminated, or inconsistent with the listing; or
  • The supplied product does not otherwise match the order confirmation.

Keep the product, shipping box, shipping label, packing materials, and order documentation. Report concerns promptly through our Contact Us page and include clear photographs.

Important Ornamental-Fish Notice

Fish Zole is intended only for aquarium fish, ornamental fish, pet fish, or another non-food aquatic species expressly identified on the current physical product label.

Unless the official physical label expressly states otherwise, this product is:

  • For expressly labeled aquarium and ornamental-fish applications only;
  • Not intended for human use;
  • Not intended for human consumption;
  • Not offered as a human prescription medicine;
  • Not intended for fish raised for human consumption;
  • Not intended for food-producing aquatic animals; and
  • Not a substitute for professional aquatic-veterinary evaluation.

Never Use Fish Zole for Humans

Fish Zole and all other aquarium products offered through FishFlexFishMox must never be taken, administered, or used by humans.

FishFlexFishMox does not provide human medical advice, diagnoses, prescriptions, dosage recommendations, pharmacy services, or human treatment plans.

Anyone experiencing a human health concern should contact a licensed physician or pharmacist.

In the event of accidental exposure, ingestion, or another emergency, contact an appropriate poison-control resource or emergency service immediately.

Do Not Automatically Use This Product for Other Animals

A product identified for ornamental fish should not automatically be used for dogs, cats, birds, livestock, poultry, or another animal species.

Even when an active-ingredient name appears familiar, appropriate animal care may depend on:

  • The animal species;
  • Size and weight;
  • Age and general condition;
  • Health history;
  • Environmental conditions;
  • Other products being used;
  • The underlying concern; and
  • Qualified veterinary evaluation.

Use Fish Zole only for an expressly identified species and application unless a qualified veterinarian provides appropriate direction and the use is permitted by applicable law.

Responsible Aquarium Care

Visible changes or health concerns in aquarium fish may have multiple possible causes, including water-quality problems, temperature instability, filtration issues, overcrowding, stress, nutritional concerns, parasites, injuries, or other environmental conditions.

The presence of visible signs does not automatically mean that a metronidazole-based product is appropriate.

Before selecting or using a specialized aquarium product:

  • Test aquarium water quality;
  • Review water temperature and recent fluctuations;
  • Check filtration and aeration;
  • Observe affected fish carefully;
  • Review recent aquarium changes or newly introduced fish;
  • Confirm appropriate stocking conditions;
  • Consider whether sensitive plants, invertebrates, or other aquarium organisms are present;
  • Read the complete current physical product label;
  • Confirm the expressly labeled species and application;
  • Avoid combining products without professional guidance; and
  • Consult a qualified aquatic veterinarian when the underlying concern is unclear, severe, or persistent.

Follow the Exact Physical Product Label

Use and handle Fish Zole only according to the current physical product label, supplier information, applicable warnings, and qualified veterinary guidance.

Do not rely on:

  • Information copied from an older Fish Zole page;
  • Instructions supplied for a 500 mg Fish Zole Forte product;
  • Information provided for a smaller package quantity;
  • Information supplied for powder packets or another format;
  • Instructions supplied by a different manufacturer or vendor;
  • Information associated with another active ingredient;
  • Advice from an unverified source; or
  • Information intended for humans or another animal species.

FishFlexFishMox customer support can assist with factual product information displayed on the website but cannot diagnose an animal, prescribe a product, recommend individualized use, or create a treatment plan.

Avoid Unapproved Product Combinations

Do not combine Fish Zole with other fish antibiotics, aquarium products, parasite-control products, supplements, water treatments, or aquarium chemicals unless the combination is supported by applicable label information or directed by a qualified veterinarian.

Using multiple aquarium products without professional guidance may create product interactions, affect aquarium water conditions, interfere with filtration, affect sensitive aquarium organisms, reduce product effectiveness, or make the underlying concern more difficult to identify.

Storage and Handling

Store Fish Zole according to the instructions supplied on the current physical product label and packaging.

Unless different instructions are provided, keep the product:

  • In its original labeled bottle;
  • With the container tightly and securely closed;
  • At the temperature stated on the physical label;
  • Protected from excessive heat and moisture;
  • Away from direct sunlight;
  • Away from children and unauthorized users;
  • Away from pets and other animals;
  • Separate from food and human medicines; and
  • In a secure storage location.

Do not transfer the tablets into an unlabeled container. Retain the original packaging for product identification, warnings, expiration information, supplier information, and lot details.
