Shop Fish Zole and Fish Zole Forte

Fish Zole and Fish Zole Forte are familiar product-family names associated with metronidazole-based products intended for expressly labeled ornamental-fish and aquarium applications.

The current collection includes:

• Fish Zole™ – Metronidazole 250 mg – 60 Tablets;
• Fish Zole™ – Metronidazole 250 mg – 100 Tablets;
• Fish Zole Forte™ – Metronidazole 500 mg – 60 Tablets; and
• Fish Zole™ – Metronidazole 500 mg – 100 Tablets.

Current availability can change. Review each individual product page for the active ingredient, strength, tablet count, supplier, stock status, expiration information, and important product notices before ordering.

Fish Zole Metronidazole 250 mg

Fish Zole listings are commonly associated with metronidazole 250 mg products for expressly stated ornamental-fish applications. Current options include 60 tablets and 100 tablets.

Before purchasing a Fish Zole product, confirm:

• That metronidazole is the listed active ingredient;
• That the selected strength is 250 mg;
• The number of capsules, tablets, packets, or other units included;
• The brand or supplier displayed on the current listing;
• The intended species and application;
• The storage and handling requirements;
• The available expiration information; and
• All applicable warnings and restrictions.

A 250 mg Fish Zole product should not be confused with a 500 mg Fish Zole Forte product. Carefully verify the selected strength and package quantity before completing checkout.

Fish Zole Forte Metronidazole 500 mg

Fish Zole Forte listings are commonly associated with metronidazole 500 mg products offered in selected package quantities. Current options include 60 tablets and 100 tablets.

Fish Zole Forte contains a different listed strength from Fish Zole 250 mg and should not be treated as interchangeable.

Review the complete product listing to confirm:

• The active ingredient;
• The listed 500 mg strength;
• The package count or net quantity;
• The capsule, tablet, packet, or powder format;
• The current manufacturer or supplier;
• The stated ornamental-fish application; and
• All product-specific instructions and notices.

Current Product Format: Tablets

The current Fish Zole and Fish Zole Forte collection contains tablet products only. Each tablet provides a clearly identified amount of metronidazole per unit.

Before ordering, confirm:

• The active ingredient is metronidazole;
• The selected strength is 250 mg or 500 mg per tablet;
• The selected package contains 60 or 100 tablets;
• The product page and physical label identify ornamental or aquarium-fish applications; and
• The current expiration, storage, warnings, and supplier information meet your requirements.

Powder packets, bulk powder, capsules, or other formats may have been offered historically or may become available separately, but they are not currently listed in this collection. Different formats should never be assumed to be directly interchangeable.

Available Package Quantities

The current collection offers 60-tablet and 100-tablet bottles in both 250 mg and 500 mg strengths.

• 250 mg – 60 Tablets;
• 250 mg – 100 Tablets;
• 500 mg – 60 Tablets; and
• 500 mg – 100 Tablets.

The quantity displayed on the selected product page, cart, checkout page, order confirmation, and physical bottle determines the exact quantity included with the purchase.

Availability may change without notice, and a previously offered count or format may become limited, temporarily unavailable, or discontinued.

Continuing the Thomas Labs Quality Standard

Thomas Labs has long been associated with the original Fish Zole and Fish Zole Forte product-family names.

FishFlexFishMox offers current products selected to continue the clear identification, dependable packaging, and quality standard customers have long associated with Thomas Labs. Visit our Thomas Labs Legacy collection to learn more.

Current products should not be represented as original Thomas Labs inventory unless the individual product page and physical packaging expressly identify them that way.

Before purchasing, review:

• The displayed brand;
• The current manufacturer or supplier;
• The complete active ingredient;
• The listed strength;
• The package quantity;
• The physical product format; and
• The current stock status.

Current Suppliers and Product Identification

Current Fish Zole products may be sourced from FishFlexFishMox-selected suppliers. The current product page and physical bottle remain the final references for the manufacturer, supplier, active ingredient, strength, format, package quantity, lot number, expiration date, storage instructions, and cautions.

A current product should not automatically be considered identical to an older Thomas Labs product solely because it contains the same active ingredient or uses a familiar product-family name.

Compare Every Product Carefully

Products within this collection may differ significantly. Before ordering, compare:

• Active ingredient: Confirm that metronidazole is expressly listed;
• Strength: Verify whether the product is 250 mg, 500 mg, or another stated concentration;
• Quantity: Confirm the number of capsules, tablets, packets, or the net powder weight;
• Format: Review whether the product is supplied as capsules, tablets, packets, or bulk powder;
• Brand: Check the current manufacturer or supplier;
• Intended application: Confirm the species and purpose stated on the listing;
• Instructions: Read the directions associated with the exact product purchased;
• Storage: Review temperature, moisture, light, and container requirements;
• Availability: Confirm that the selected variation is currently available; and
• Restrictions: Read all applicable purchasing, shipping, and responsible-use notices.

Never select a product based only on its bottle design, capsule appearance, package color, photograph, or similarity to another product name.

Product Availability May Change

Fish Zole and Fish Zole Forte availability may change because of:

• Manufacturer production schedules;
• Supplier inventory;
• Product discontinuations;
• Packaging or branding updates;
• Ingredient availability;
• Distribution and transportation conditions;
• Changes in customer demand;
• Legal or carrier restrictions; and
• Other operational considerations.

An unavailable historical product may not return to stock. When appropriate, a separately identified metronidazole product from a selected supplier may be offered within this collection.

Current Listed Expiration: 08/2027

The current catalog-listed expiration date for the Fish Zole and Fish Zole Forte product family is 08/2027.

Expiration dates may vary by supplier shipment, manufacturing batch, strength, package quantity, or product variation. The date printed on the physical bottle received is the final product-specific expiration date.

Review our Fish Antibiotic Expiration Dates collection for current listed expiration information. Customers who need confirmation for a particular product may also contact customer support before ordering.

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

Packaging May Vary

Manufacturers and suppliers may update bottle styles, labels, logos, package colors, closures, safety seals, packet designs, or other visual details without prior notice.

The product received may therefore look different from an older photograph while still matching the essential active ingredient, strength, quantity, format, and supplier displayed on the current product page.

Contact customer support promptly if the product received does not match the essential details shown in your order.

Inspect Products After Delivery

Before opening or using a product, inspect the shipping package, product container, label, seal, and contents.

Do not use the product if:

• The bottle, packet, jar, or container is broken or leaking;
• A required safety seal appears missing or compromised;
• The label is missing or unreadable;
• The product differs from the item ordered;
• The contents appear inconsistent with the listing; or
• The shipping package shows substantial damage.

Retain the product, shipping box, shipping label, and all protective packaging. Report the issue through our Contact Us page and include clear photographs.

Important Ornamental-Fish Notice

Products in this collection are intended only for ornamental fish, aquarium fish, pet fish, or another non-human application expressly identified on the applicable product page and official labeling.

Unless the official product label expressly states otherwise, products in this collection are:

• For ornamental or aquarium fish use only;
• Not intended for human use;
• Not intended for human consumption;
• Not offered as human prescription medicines;
• Not intended for food-producing fish or animals; and
• Not a substitute for professional veterinary care.

Never Use Fish Zole for Humans

Fish Zole, Fish Zole Forte, metronidazole powder products, and other products offered in this collection must never be taken, administered, or used by humans.

FishFlexFishMox does not provide:

• Human medical advice;
• Human diagnoses;
• Human prescriptions;
• Human dosage recommendations;

• 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.

Responsible Aquarium Care

Visible signs in aquarium fish may result from water-quality problems, temperature instability, overcrowding, environmental stress, nutritional deficiencies, parasites, injuries, or other health conditions.

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

Before selecting any fish-care product:

• Test the aquarium water;
• Review temperature and environmental conditions;
• Observe all affected fish carefully;
• Review recent aquarium changes or additions;
• Read the complete product page and physical label;
• Confirm the stated species and application;
• Avoid combining products without appropriate professional guidance; and
• Consult a qualified veterinarian or aquatic-animal health professional when the cause is uncertain.

Consult a Qualified Professional

Professional veterinary or aquatic-animal guidance is especially important when:

• The underlying problem cannot be identified confidently;
• Several fish are affected;
• The condition is severe, recurring, or worsening;
• The aquarium contains sensitive species;
• The fish has another known health concern;
• More than one product is being considered;
• An unexpected reaction occurs;
• A product has not produced the expected result; or
• The correct product, measurement, or application is uncertain.

Our customer-support team can provide general product information displayed on FishFlexFishMox.com but cannot diagnose an animal or prescribe treatment.

Avoid Unapproved Product Combinations

Do not combine metronidazole products with other fish antibiotics, parasite-control products, aquarium treatments, supplements, or chemical products unless the combination is expressly supported by the applicable instructions or directed by a qualified veterinarian.

Using multiple products without appropriate guidance may increase risk, affect aquarium conditions, reduce product effectiveness, or make it more difficult to identify the underlying problem.

Storage and Handling

Store each product according to the directions provided on its physical label, packaging, product page, or manufacturer documentation.

Unless different instructions are supplied, products should generally be kept:

• In their original labeled container;
• Securely closed;
• Protected from excessive heat and moisture;
• Away from direct sunlight;
• Away from children and unauthorized users;
• Separate from food and human medicines; and
• In a secure location that helps prevent accidental use.

Do not transfer products into unlabeled containers. Retain the original packaging for identification, directions, expiration information, and lot details.
