    Maintain the health of your pet fish using Fish Mox. This antibacterial product treats common bacterial diseases found in fish, for example, pseudomonas genera, aeromonas and mycobacterial diseases like chondrococcus and gill diseases. It exerts bactericidal action, so it is effective against both Gram-positive and some Gram-negative bacteria.

    Application of the drug involves adding the contents of the pull-apart capsules to every 10 gallons of water and repeating this treatment in 24 hours. A 20% water change and the use of a charcoal filter to clean the water should be done prior to each treatment. The type of infection and its severity will determine the treatment duration. However, the extended medication baths should be continued for a minimum of five days and a maximum of 10 days.

    This product is an amoxicillin antibiotic of standard pharmacy quality. Fish Mox is recommended for use in fish tanks, on aquarium and ornamental fish.

    Snappy Sneeze Smasher by Beali from Bronx NY02/05/2013

    I have two cats that go outside. I also do cat rescue and feed a small colony of cats. Recently during the winter, four of the cats, including mine, started sneezing. I was going on a trip and immediately ordered the Fish Mox which came before I left. I gave the cats Fish Mox and so did the cat sitter while I was away. When I returned four days later, none of the cats were sneezing. Very happy with the product.

    Fish Mox by NoDRs12/21/2012

    About three weeks ago my fish found himself with a bad case of strep throat. It was so bad that my fish was unable to speak, so my fish had to miss several days of work. My fish had had this happen once before, about three years ago, and the veteranarian had instructed my fish to take 250mg of Amoxicilin 3 times daily for 7 days. I tried to take my fish back to the veteranarian to have my fish examined this time as well, but the vet clinic wanted my fish to wait for three weeks before they would be willing to see my fish. My fish could not miss three weeks of work while waiting for these people to have an opening. Contacting you here at, I was able to purchase the antibiotics needed to treat my fish's infection and kill off the bacteria causing the strep throat so my fish could go back to living his life in comfort. The package arrived quickly and the medication was exactly what I had needed. Totallypets, my fish is very grateful for the services you offer. Thank you.

    works great by blessed acres09/19/2013

    Fish amoxy by Nancy from Chicago12/27/2013

    This product is a lifesaver for a feral cat when he can't be medicated any other way other than sprinkling in food. My guy had an abcess and this worked like a charm! Sprinkle l/2 of a 250 in the food....

    great product by jd04/30/2013

    The order was handled quickly and accurately. Product is excellent. Will continue to use this service.

    A few kittens began to look sickly so I was advised to buy Fish Mox and treat my 10 cats and 4 kittens by mixing one 250 mg capsule in 1 gallon of water and giving the cats only treated water.

    Wrong Item by Unsatisfied07/03/2012

    I received the wrong item and have yet to get my refund. I am very unhappy with this company and will recommend to anyone I talk to not to make a purchase from this company. I will also be emailing Amazon, which is how I found out about this company. Terrible customer service and terrible company.

    super happy!! by LLJZMM from Wake Forest, NC04/30/2013

    With 4 dogs, there's always some sort of issue, it seems! While not a proponent of overused antibiotics, there's a time and place for them, and it's nice to be able to provide what my dogs need without the costly veterinary office visit (and inevitable testing) that comes along with it. Will be keeping a stash of these from now on, to cover my bases for those 7-14 day stretches when I know that an antibiotic is in order for one of my fur kids!

    Fish Mox by Mountain Suze from Westcliffe, CO11/23/2012

    We have a Red Eared Slider Turtle. They carry Somenella. This product helps keep the algea down and hopefully reduces the Somenella. I am also happy with the coupon code toward $ off my next order.

    Good product by Jeff03/01/2012

    Good Product by Majestic Fish03/08/2014

    Fish Mox seems to be a good product. No issues with it. And EntirelyPets delivers rapidly. All-in-all, a good experience.

    Great Product and Customer Service by Cat Lady from Easton, PA02/04/2011

    I purchased this product after reading reviews on how well it worked on cats. I take care of several stray cats and one had a very serious upper respiratory infection. Since starting the medication, she has improved immensely. I also want to say that the customer service was great. I received the product in only 3 days after ordering. Keep up the great service. I would not think twice about ordering from them again.

    Good product by Bob10/23/2012

    Easy to use and effective. The variety of sizes makes purchasing quite easy. The order was filled quickly and efficiently. A very good experience

    by Bob07/31/2012

    Fish Mox was reccomended for my cats by a friend who used it on his. I have a barn full of cats that were kind of sickly all the time. I got the Fish Mox, dissolved one capsule in one gallon of water everyday. In about a week, I noticed that most of the cats looked alot better. Now it has been about three weeks and they all look fine. I continue to give it to them every day to make sure to get rid of the sickness completely.

    by krista11/12/2012

    while the value was good the fact that the two bottles of 100 tablets i purchased have an expiration date of december 2012. I ordered them in October. Doesn't give us much time to utilize them. I will try again though.

    good for respiratory onset! by Ms Ren06/06/2014

    I used this product to cure a 2 year old turtle-aquatic..750mg in water he lived in alone for 3 weeks..he is better , not listing and returned to the community pond. I was thrilled to fine this. Reptiles do not do well with injections due to inguinal area being near kidneys. This method of use allowed him to drink in the water-infused with the antibiotic- naturally while eating. Great service .

    Love this item! by ginrawls01/20/2013
