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

Two Active Ingredients Per Tablet

Each Fish Sulfa tablet is identified as containing:

• Sulfamethoxazole: 800 mg per tablet;
• Trimethoprim: 160 mg per tablet.

Together, these two active ingredients provide a combined listed strength of 960 mg per tablet.

The strength may appear on product labels, supplier records, or product listings in several equivalent formats, including:

• Sulfamethoxazole/Trimethoprim 800/160 mg;
• Sulfamethoxazole 800 mg plus trimethoprim 160 mg;
• SMZ-TMP 800/160 mg;
• Fish Sulfa 960 mg;
• Fish Sulfa Forte 960 mg; or
• 960 mg combined active ingredients per tablet.

These descriptions refer to the same total two-ingredient strength. The 960 mg figure is the combined amount and should not be interpreted as 960 mg of each active ingredient.

Verify the Complete 800/160 mg Formula

Before ordering, confirm that the product identifies both active ingredients and their corresponding strengths.

The correct product specifications should display:

• Sulfamethoxazole as the first active ingredient;
• 800 mg as the sulfamethoxazole strength;
• Trimethoprim as the second active ingredient;
• 160 mg as the trimethoprim strength;
• 960 mg as the combined active-ingredient strength;
• Tablets as the physical product format; and
• 100 tablets as the package quantity.

Do not select this product based only on the word “Sulfa.” Aquarium products with similar names may contain different active ingredients, strengths, ingredient ratios, formats, or package quantities.

Large 100-Tablet Bottle

This listing includes one bottle containing 100 Fish Sulfa tablets.

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

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

• Fish Sulfa™;
• Sulfamethoxazole/Trimethoprim;
• 800/160 mg or 960 mg combined strength;
• 100 Tablets;
• Tablets as the physical product format;
• One bottle unless another package 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 formula, strength, format, and quantity included with the purchase.

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

Understanding the 960 mg Strength

The 960 mg strength is calculated by combining the amounts of both active ingredients:

• 800 mg sulfamethoxazole;
• 160 mg trimethoprim;
• Total combined amount: 960 mg per tablet.

A listing that displays only “960 mg” should still be checked carefully to verify the complete active-ingredient breakdown.

Products containing sulfamethoxazole 400 mg and trimethoprim 80 mg have a combined strength of 480 mg and should not be confused with this 960 mg product.

Always rely on the complete physical product label to confirm the precise amount of each ingredient in the bottle supplied with your order.

Fish Sulfa and Fish Sulfa Forte

Fish Sulfa and Fish Sulfa Forte are product-family names associated with sulfamethoxazole-and-trimethoprim aquarium products.

The 800 mg/160 mg combination has historically been associated with the Fish Sulfa Forte name because it provides a combined strength of 960 mg per tablet.

This new listing uses the customer-facing title Fish Sulfa – Sulfamethoxazole/Trimethoprim 960 mg – 100 Tablets.

The physical bottle may display:

• Fish Sulfa;
• Fish Sulfa Forte;
• Fish SulfaTrim;
• SMZ-TMP;
• Sulfamethoxazole/Trimethoprim;
• 800/160 mg; or
• Another supplier-approved product presentation.

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

The essential identifying details are both active ingredients, the individual strength of each ingredient, the combined 960 mg strength, tablet format, 100-tablet count, supplier information, and expressly labeled application.

Compare Available Fish Sulfa Package Quantities

Fish Sulfa and Fish Sulfa Forte products may be offered in several separately identified package quantities.

Available or previously offered configurations may include:

• Fish Sulfa 960 mg – 30 Tablets;
• Fish Sulfa 960 mg – 60 Tablets;
• Fish Sulfa 960 mg – 100 Tablets; and
• Other clearly identified supplier-approved package options.

This product page is specifically prepared for the 100-tablet bottle.

Different package quantities may vary in price, supplier, manufacturer, packaging design, tablet appearance, inventory batch, lot number, and expiration date.

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

Understanding This Product Listing

This product should be identified using the following essential specifications:

• Product family: Fish Sulfa;
• First active ingredient: Sulfamethoxazole;
• First ingredient strength: 800 mg per tablet;
• Second active ingredient: Trimethoprim;
• Second ingredient strength: 160 mg per tablet;
• Combined strength: 960 mg per tablet;
• Physical format: Tablets;
• Package quantity: 100 tablets; and
• Intended application: Expressly labeled ornamental and aquarium fish.

Products containing different active ingredients, strengths, ratios, formats, or package quantities should not be treated as interchangeable merely because they appear within the same broader aquarium-products category.

Fish Sulfa vs. Other Fish Products

The sulfamethoxazole-and-trimethoprim combination is separately identified from other products in the FishFlexFishMox catalog.

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

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

Always verify the exact active ingredients shown 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;
• Both active ingredients;
• The strength of each active ingredient;
• The combined 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 Sulfa strength, ingredient ratio, package quantity, or supplier.

Current Catalog-Listed Expiration: 08/2027

The current catalog-listed expiration date for Fish Sulfa 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 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 it has been 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 Sulfa should arrive in its original, clearly labeled bottle or supplier-approved packaging.

• 800 mg as the sulfamethoxazole strength;
• Trimethoprim as an active ingredient;

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

• Label layout;
• Typography;

• Supplier information;
• Lot-number placement; and

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

Inspect Fish Sulfa After Delivery

Before opening or using Fish Sulfa, 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;

• A required safety seal appears missing or compromised;
• The physical product label is missing or unreadable;
• Sulfamethoxazole is not identified as an active ingredient;
• Trimethoprim is not identified as an active ingredient;
• The label does not identify the expected 800/160 mg formula;
• The combined strength is not 960 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 Sulfa 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 Sulfa for Humans

Fish Sulfa 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 active-ingredient names appear familiar, appropriate animal care may depend on the species, size, age, health history, environmental conditions, other products being used, and qualified veterinary evaluation.

Use Fish Sulfa 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 sulfamethoxazole-and-trimethoprim 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 Sulfa 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 Sulfa page;
• Information supplied for a 400/80 mg or 480 mg product;
• Information provided for a smaller package quantity;
• Instructions supplied by a different manufacturer or vendor;
• Information associated with a single-ingredient sulfa product;
• 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 Sulfa 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 Sulfa 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.
