Fish Flex Forte
Ive tried a number of product for my fish, I have 24 different tanks, and once in a while one or two get infected with some form of bacterial infection. Time after time the Fish flex forte works.

fish flex immune booster+
Excellent. This potent 500mg should be administered with 250mg amoxicillin to offset the 'egg'. Good for large breeds.

Did the job
We got this for an unidentified pit bull skin ailment. It was a raised, bumpy rash on his back that spread to his sides. A friend with a pit bull recommended fish flex as a remedy for their myriad of skin problems.

We had to give it to him for about three weeks, but it did seem to work eventually. Definitely better than a zillion dollar vet bill!!!

Entirely Pets had the best price when you include shipping, and we got it really fast. Woo hoo!

Cost Effective
This is the second time I have ordered Fish Flex Forte for my dog. The product arrives quickly, and without the added expense of a visit to the vet and inflated cost of the product itself

Works for Dogs!
My dog has chronic skin problems and periodically goes on antibiotics. When his skin problems started for the third time, I sought a less expensive solution and found these. Worked perfectly! This is exactly the same thing my vet gives him at 1/2 the price (and no vet visit fee). Of course, always take your doggy to the vet first for diagnosis.
