Always verify the physical product label before handling or using Fish Sulfa Forte. Confirm both active ingredients, the strength of each ingredient, the tablet count, intended species, expiration date, lot information, storage requirements, warnings, and current manufacturer instructions.

Two Active Ingredients Per Tablet

Every Fish Sulfa Forte tablet is identified as containing two active ingredients:

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

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

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

• Sulfamethoxazole/Trimethoprim 800/160 mg;
• Sulfamethoxazole 800 mg plus trimethoprim 160 mg;
• 800 mg/160 mg combination tablets; or
• 960 mg combined active ingredients per tablet.

These formats describe the same two-ingredient strength and should not be interpreted as separate product options.

Verify the Complete 800/160 mg Strength

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

The correct product information should identify:

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

Do not select the product based only on the words “Fish Sulfa.” Products with similar names may contain different active ingredients, concentrations, strengths, formats, manufacturers, or package quantities.

Practical 60-Tablet Bottle

This listing includes one clearly identified bottle containing 60 Fish Sulfa Forte tablets.

The larger-count package provides twice the tablet quantity included in the separately listed 30-tablet bottle.

Before completing checkout, verify that the cart and order confirmation display:

• Fish Sulfa Forte™;
• Sulfamethoxazole/Trimethoprim;
• 800/160 mg;
• 60 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 product title, selected package option, cart, checkout page, order confirmation, and physical bottle determine the exact quantity included with the purchase.

Never rely only on a product photograph when confirming package quantity. Product images may remain in use after a manufacturer updates part of the label or packaging design.

30 Tablets vs. 60 Tablets

Fish Sulfa Forte may be offered in separately identified 30-tablet and 60-tablet package options.

• 30 Tablets: One bottle containing 30 tablets;
• 60 Tablets: One bottle containing 60 tablets.

Both package sizes contain the same listed combination of sulfamethoxazole 800 mg and trimethoprim 160 mg per tablet. The principal differences are the total number of tablets, product price, supplier, packaging, inventory batch, and availability.

This product page is specifically for the 60-tablet bottle. Customers seeking the smaller package should select the separately listed Fish Sulfa Forte 800/160 mg 30-tablet version.

Different package quantities may be supplied from separate manufacturing or inventory batches and may therefore display different lot numbers, packaging details, and expiration dates.

Understanding the Fish Sulfa Forte Listing

Fish Sulfa Forte is the product-family name used for this sulfamethoxazole-and-trimethoprim combination aquarium product.

This 60-tablet listing should be identified using the following essential details:

• Product family: Fish Sulfa Forte;
• 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; and
• Package quantity: 60 tablets.

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

Important Ornamental-Fish Notice

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

Unless the official product 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 Forte for Humans

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

FishFlexFishMox does not provide human medical advice, human diagnoses, human prescriptions, human 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 or ingestion, 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.

Appropriate animal care may depend on the species, size, weight, age, health history, environmental conditions, other products being used, the underlying concern, and qualified veterinary evaluation.

Use Fish Sulfa Forte 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 issues, temperature instability, filtration problems, overcrowding, stress, nutritional concerns, parasites, injuries, or other aquarium 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 all 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 intended species and application;
• Avoid combining products without professional guidance; and
• Consult a qualified aquatic veterinarian when the underlying concern is uncertain.

Follow the Exact Physical Product Label

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

Do not rely on:

• Information copied from an older product page;
• Information provided for the 30-tablet package;
• Instructions supplied for another sulfamethoxazole strength;
• Instructions supplied for another trimethoprim strength;
• Instructions supplied by another manufacturer or vendor;
• Information associated with a single-ingredient product;
• Advice from an unverified online 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 Forte with other fish antibiotics, aquarium medications, parasite-control products, supplements, water treatments, or chemical products unless the combination is supported by the applicable product 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 Forte according to the instructions supplied on the current physical product label and packaging.

Unless different instructions are supplied, 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 location that helps preserve product integrity.

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