A Focused Selection for Aquarium Keepers

FishFlexFishMox is designed for customers seeking specialized fish-care products without searching through thousands of unrelated items.

The collection makes it easier to compare products by:

• Complete product name;
• Active ingredient;
• Strength or concentration;
• Tablet or capsule format;
• Package quantity;
• Current brand or supplier;
• Live availability; and
• Intended species and application.

Current Product Formats

The current live Medicines collection primarily displays tablet and capsule products in clearly identified counts and strengths.

Tablets

Tablet products provide a pre-manufactured amount of the listed active ingredient per tablet. Confirm the strength per tablet, total tablet count, supplier, and intended application on the exact product page.

Capsules

Capsule products are offered in selected strengths and package quantities. Confirm the amount per capsule and total capsule count before checkout.

Powders, Packets, and Deworming Products

Powder jars, single-dose packets, and deworming or parasite-control products are not guaranteed to be included in the current live Medicines collection. They should be considered available only when a dedicated product page is actively displayed and clearly identifies the product, ingredients, format, intended species, and current stock status.

Thomas Labs Legacy and Current Suppliers

Thomas Labs has historically been associated with well-known product-family names including Fish Mox, Fish Flex, Fish Flox, Fish Doxy, Fish Zole, and Fish Pen.

Original Thomas Labs inventory may be limited, discontinued, or unavailable. The use of a familiar product-family name does not automatically mean that a current listing is manufactured by Thomas Labs.

FishFlexFishMox continues to organize products around familiar aquarium-care categories while clearly identifying the current product, supplier, strength, quantity, and format on each listing.

Products associated with Aqua Soma Labs or another supplier should be considered part of the current catalog only when that supplier is expressly identified on the applicable live product page and physical label.

Before purchasing, verify:

• The displayed brand or supplier;
• The complete active ingredient;
• The strength or concentration;
• The package quantity;
• The physical product format;
• The stated ornamental-fish or other eligible application; and
• The current availability and product notices.

Selected Bird-Care Products

Some products may be expressly labeled for both ornamental fish and selected pet-bird applications. Review the exact product page and physical label before use.

For products organized specifically around bird-care categories, visit the Bird Antibiotics, Bird Biotic, Bird Sulfa, and Bird Zithro collections.

A product labeled only for ornamental fish should not automatically be used for birds. A bird-labeled product should not automatically be used for another species.

Review Every Product Before Ordering

Products in this collection may differ significantly in ingredient, strength, format, package quantity, supplier, intended species, and official directions.

Before placing an order, confirm:

• The complete product name;
• The listed active ingredient;
• The strength or concentration;
• The tablet, capsule, or other expressly stated format;
• The package quantity;
• The current brand or supplier;
• The intended species and application;
• The storage instructions;
• The expiration information available;
• All warnings and restrictions; and
• The selected variation and checkout quantity.

Do not purchase a product based only on its appearance, bottle design, capsule or tablet color, photograph, historical name, or similarity to another listing.

Expiration Dates and Product Freshness

Expiration dates vary by product, supplier, production batch, and inventory available during fulfillment.

Visit the Fish Antibiotic Expiration Dates page for the current published information. The expiration date printed on the physical product supplied is the final product-specific reference.

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 expressly confirmed for the applicable order.

Packaging May Vary

Manufacturers and suppliers may update labels, bottles, package designs, colors, logos, closures, or safety seals without prior notice.

The product received may 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 the order.

Inspect Products After Delivery

Before opening or using a product, inspect the shipping package, 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 the Contact Us page and include clear photographs.

Responsible Product Use

All products must be used only for the species, applications, and purposes expressly stated on the applicable product page, physical label, packaging, or manufacturer documentation.

Customers are responsible for:

• Reading all instructions and warnings;
• Following the information supplied with the exact product purchased;
• Maintaining appropriate aquarium conditions;
• Using accurate measuring equipment when required;
• Storing products as directed;
• Keeping products away from children and unauthorized users;
• Confirming applicable purchasing or use restrictions; and
• Consulting a qualified professional when the correct product or course of action is uncertain.

Anyone seeking assistance with a human health concern should contact a licensed physician or pharmacist. In an accidental-exposure or ingestion emergency, contact an appropriate poison-control resource or emergency service immediately.

Consult a Qualified Professional

Water-quality problems, environmental stress, nutrition, parasites, injuries, and other conditions can produce similar visible signs in aquarium fish.

Consult a qualified veterinarian or aquatic-animal health professional when:

• More than one product is being considered;
• An unexpected reaction occurs;

Storage and Handling

Store every 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, moisture, and 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, instructions, expiration information, and lot details.
