Fish Flex (Cephalexin)

is a broad spectrum antibiotic used to treat a wide range of non-specific bacterial infections during the most active and multiplying stages of infection.

Directions: Add contents of one capsule (250 mg) into aquarium for each 10 gallons of water to be treated. Repeat in 24 hours. It is suggested that a partial water change is made between treatments. While the duration of treatment depends on type and severity of infection, it is recommended that extended medication baths continue for a minimum of 5 days & for not more than 10 days. Discontinue treatment if no improvement is noted within 5 days.

Caution: For aquarium and ornamental fish only. Not for human use. Keep out of the reach of children. Keep container tightly closed and in a cool dry place. Not to be given to fish intended for food use.

Great product
This product works great. It does the trick for many incidental bacterial infections. I wish the experiration date wasn't so short, but it still works after the date has passed; just have to use more.

For my dog
Seasonal allergies mean breakouts for my dog. Rashes, scratching. A mess. The vet says Cephalexin twice a day. After too many vet visits to get the antibiotic, my dog takes this, which is the same thing. Cuts out the vet visit, since I do know what he needs to take. Do not skip the vet, though.

Cephalexin powder capsules
This borad range antibiotic is great for fish tanks but can also be applied to other rescue animals as long as rescue personnel know dosage, etc.

This has been a savoir for many cats in destressed colonies and while I'm not a vet, the practice shows the proof.

Understand the intent of the med and use it accordingly but use it for cats you cannot touch. In food it goes down without complaint.

Fish Flex
I bought this for my diabetic dog who has chronic urinary tract infections. Cost is less than what the vet would charge and I don't have to stress my dog out taking her to the vet just for antibiotics. Works well and fast shipping!

Best Purchase Experience Ever
Fish Flex works wonders! When I needed this broad spectrum antibiotic, I needed it quickly. I shopped around - EntirelyPets had the best prices. My original idea was to order it through EntirelyPets & to buy a small amount locally. I placed my order & in a day, I had my product! I have the good fortune of living in an area close to an EntirelyPets' warehouse - they process orders & ship so quickly! I have placed many orders over the years & have always received them in a day (with the regular shipping). I was sent the wrong product once. I called EntirelyPets Customer Service. They readily emailed me a postage paid label to return the wrong product; meanwhile they shipped the correct product & I received it the very next day! I am totally hooked on doing business with EntirelyPets! Great prices, excellent service, a user-friendly website, & polite, efficient customer service!
