• Selected tablet or capsule package quantities;
• Thomas Labs products when available;
• AquaSoma Labs alternatives;

Not every package count, format, brand, or product variation will be available at all times. Review the individual product page for current ingredient information, strength, quantity, format, manufacturer, stock status, expiration information, and important product notices.

Sulfamethoxazole 800 mg and Trimethoprim 160 mg

Fish Sulfa Forte products are commonly associated with a combination of sulfamethoxazole 800 mg and trimethoprim 160 mg per applicable tablet or unit.

Because this is a combination product, customers should confirm both active ingredients and both listed strengths before completing a purchase.

Before ordering, verify:

• That sulfamethoxazole is expressly listed as an active ingredient;
• That trimethoprim is expressly listed as an active ingredient;
• The amount of each ingredient per tablet, capsule, or applicable unit;
• The total number of units included;
• The physical product format;
• The brand or manufacturer;
• The stated ornamental-fish application;
• The storage requirements;
• The available expiration information; and
• All applicable warnings and restrictions.

Do not purchase a product based only on the words “Fish Sulfa” or “Sulfa Forte.” Products with similar names may differ in ingredients, strengths, quantities, manufacturers, or official directions.

Available Package Quantities

Fish Sulfa Forte products may be offered in different package quantities depending on current inventory and supplier availability.

Available listings may include selected 30-count, 60-count, 100-count, or other expressly stated package configurations.

The package count displayed on the selected product page and variation is the quantity included with that purchase. A historical package quantity mentioned elsewhere should not be used to determine the contents of a current listing.

Some products may also be offered as multipacks. A multipack contains the number of separate bottles or packages expressly stated in the listing and should not be confused with the number of tablets or units contained in each bottle.

Thomas Labs Fish Sulfa Forte

Thomas Labs has historically been associated with the Fish Sulfa Forte product-family name.

Original Thomas Labs inventory may be limited, discontinued, or unavailable. The appearance of a familiar Fish Sulfa Forte name does not automatically mean that the current product is manufactured by Thomas Labs.

Before ordering, review:

• The displayed brand;
• The current manufacturer or supplier;
• The complete active-ingredient combination;
• The listed strength of each ingredient;
• The package quantity;
• The physical product format; and
• The current availability.

AquaSoma Labs Sulfa Products

FishFlexFishMox may offer sulfamethoxazole and trimethoprim aquarium products from AquaSoma Labs when available.

AquaSoma Labs products should be reviewed according to their own current labels, ingredient strengths, quantities, packaging, intended applications, and manufacturer information.

A product from one supplier should not automatically be considered identical to an older Thomas Labs product solely because it contains a similar active-ingredient combination.

Compare Every Product Carefully

Products within this collection may differ in several important ways. Before ordering, compare:

• Active ingredients: Confirm that both sulfamethoxazole and trimethoprim are expressly listed;
• Strengths: Verify the stated amount of each active ingredient;
• Quantity: Confirm the total number of tablets, capsules, or other units included;
• Format: Review whether the product is supplied as tablets, capsules, powder, or another format;
• Brand: Check the current manufacturer or supplier;
• Intended use: Confirm the species and application stated on the product page and label;
• 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, tablet appearance, label color, photograph, or similarity to another product name.

Safety-Sealed Packaging

Available products may be supplied in safety-sealed bottles or other manufacturer-approved packaging.

The applicable packaging may display:

• The complete product name;
• Both active ingredients;
• The strength of each ingredient;
• The package quantity;
• The intended ornamental-fish or aquarium application;
• The manufacturer or supplier;
• The expiration date;
• Storage information; and
• Important warnings or directions.

Always review the physical label and packaging supplied with the product. Do not use directions taken from another brand, package quantity, strength, product format, or discontinued listing.

Product Availability May Change

Fish Sulfa Forte availability may change because of:

• Manufacturer production schedules;
• Supplier inventory;
• Product discontinuations;
• Packaging or branding changes;
• Active-ingredient availability;
• Distribution and transportation conditions;
• Customer demand;
• Legal or carrier restrictions; and
• Other operational considerations.

An unavailable Thomas Labs product may not return to stock. When appropriate, a separately identified product from AquaSoma Labs or another selected supplier may be offered within this collection.

The addition of an alternative product does not mean that it is identical to a previously available product. Review the complete current listing before ordering.

Expiration Dates and Inventory Freshness

Expiration dates vary according to the product, manufacturer, supplier shipment, production batch, and inventory available during fulfillment.

FishFlexFishMox works to maintain active inventory and provide practical expiration dates from the stock available when each order is prepared.

Customers who require expiration information for a particular listing may contact customer support before ordering.

A specific lot number or expiration date is not guaranteed unless it has been expressly confirmed for the applicable order.

Product Packaging May Vary

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

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

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

Inspect Products After Delivery

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

Do not use the product if:

• The bottle, package, 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.

FishFlexFishMox does not provide:

• Human medical advice;
• Human diagnoses;
• Human prescriptions;

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 sulfamethoxazole and trimethoprim product is appropriate.

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 particularly 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;
• The animal is receiving another product;
• More than one product is being considered;
• An unexpected reaction occurs;
• The selected product has not produced the expected result; or
• The correct product or course of action is uncertain.

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

Avoid Unapproved Product Combinations

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

Using several products together without appropriate guidance may:

• Increase the possibility of adverse effects;
• Affect aquarium water conditions;
• Create product interactions;
• Reduce product effectiveness;
• Affect sensitive fish or aquarium organisms; 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 or unauthorized use.

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