Cephalexin 250 mg Per Capsule

Each Fish Flex capsule is identified as containing 250 mg of cephalexin monohydrate.

The clearly stated strength distinguishes this Fish Flex product from Fish Flex Forte products containing 500 mg per capsule.

Before ordering, confirm:

• That cephalexin monohydrate is identified as the active ingredient;
• That the strength is 250 mg per capsule;
• That the package contains 100 capsules;
• That the product format is capsules;
• That the intended ornamental-fish application matches the current label;
• That the current price and availability are acceptable;
• That the available expiration information meets your requirements; and
• That all warnings and storage information have been reviewed.

Do not select a product based only on the name “Fish Flex.” Fish Flex and Fish Flex Forte products may differ by active-ingredient strength, package quantity, supplier, product packaging, and availability.

Convenient 100-Count Bottle

This listing includes one bottle containing 100 Fish Flex capsules.

The 100-count format provides a larger package option than the separately listed Fish Flex 250 mg 30-count product.

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

• Fish Flex™;
• Cephalexin 250 mg;
• 100 Count;
• One bottle unless another configuration is expressly stated;
• The correct product price; and
• The correct U.S. shipping destination.

The quantity displayed in the product title, cart, checkout, order confirmation, and physical bottle determines what is included with the purchase.

30 Count vs. 100 Count

Fish Flex cephalexin 250 mg may be offered as separate 30-count and 100-count products.

• 30 Count: One bottle containing 30 capsules;
• 100 Count: One bottle containing 100 capsules.

Both products contain the same listed strength of 250 mg per capsule, but the total number of capsules and product price differ.

This listing is specifically for the 100-count bottle. Customers seeking the smaller package should select the separately listed Fish Flex 250 mg 30-count product.

Never rely only on a product photograph when confirming the package quantity. Review the complete product title, details, cart, and order confirmation.

Fish Flex vs. Fish Flex Forte

Fish Flex and Fish Flex Forte share cephalexin as their identified active ingredient, but they commonly differ in strength.

• Fish Flex: Cephalexin 250 mg per capsule;
• Fish Flex Forte: Cephalexin 500 mg per capsule.

Available collection products may include:

• Fish Flex cephalexin 250 mg – 30 Count;
• Fish Flex cephalexin 250 mg – 100 Count;
• Fish Flex Forte cephalexin 500 mg – 30 Count; and
• Fish Flex Forte cephalexin 500 mg – 100 Count.

A 250 mg product should not be confused with a 500 mg product. A 30-count product should also not be confused with this 100-count bottle.

Important Ornamental-Fish Notice

Fish Flex is intended only for ornamental fish, aquarium fish, pet fish, or another non-human application expressly identified on the current product page and physical label.

Unless the official product labeling expressly states otherwise, this product is:

• For ornamental and aquarium-fish use 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 animals; and
• Not a substitute for professional veterinary evaluation.

Never Use Fish Flex for Humans

Fish Flex, Fish Flex Forte, and 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 or ingestion, contact an appropriate poison-control resource or emergency service immediately.

Do Not Automatically Use Fish Products for Other Animals

A product identified for ornamental fish should not automatically be used for dogs, cats, birds, livestock, or another animal species.

Even when an active-ingredient name appears familiar, appropriate animal care may depend on the species, size, weight, age, health history, environmental conditions, other products being used, and professional evaluation.

Use this product only for its expressly identified species and application unless a qualified veterinarian provides appropriate direction and the use is permitted by applicable law.

Responsible Aquarium Care

Visible concerns in aquarium fish may be associated with water-quality problems, environmental stress, temperature instability, overcrowding, nutrition, parasites, injuries, or other conditions.

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

Before selecting 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 new additions;
• Confirm appropriate stocking conditions;
• Read the complete product page and physical label;
• Confirm the intended species and application;
• Avoid combining products without professional guidance; and
• Consult a qualified veterinarian or aquatic-animal professional when the underlying concern is uncertain.

Follow the Exact Product Label

Use and handle Fish Flex only according to the current physical product label, manufacturer information, and appropriate professional guidance.

Do not rely on:

• Information copied from an older product listing;
• Information associated with Fish Flex Forte 500 mg;
• Information provided for the 30-count product;
• Instructions supplied for another manufacturer or brand;
• Advice from an unverified online source; or
• Information intended for humans or another animal species.

FishFlexFishMox customer support can assist with product information displayed on our 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 Flex with other fish antibiotics, aquarium medicines, parasite-control products, supplements, or chemical treatments unless the combination is expressly supported by the applicable product information or directed by a qualified veterinarian.

Using multiple products without appropriate professional guidance may:

• Increase the possibility of adverse effects;
• Create product interactions;
• Affect aquarium water conditions;
• Reduce product effectiveness;
• Affect sensitive fish or aquarium organisms; or
• Make it more difficult to identify the underlying concern.

Storage and Handling

Store Fish Flex according to the information supplied on the physical product label and packaging.

Unless different instructions are supplied, keep the product:

• In its original labeled bottle;
• With the 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 preserve product integrity.

Do not transfer the capsules into an unlabeled bottle or container. Retain the original packaging for product identification, warnings, expiration information, and lot details.
