About Fish Amoxicillin

Aquarium fish treatments and pet health supplies from one US store

Fish Amoxicillin is an online store run by Fish Amoxicillin Inc in Valdosta, Georgia. We sell treatments for ornamental aquarium fish alongside everyday health and care products for dogs, cats, horses and livestock, from established brands such as Aqua Soma Labs, Elanco, Ceva, Dechra and Merck Animal Health. Every product page shows the price, the available sizes and the stock status before you order.

What are fish antibacterials?

Fish antibacterials are capsules or tablets labeled for treating bacterial infections in ornamental fish, such as fin rot, ulcers and columnaris. Our range includes fish amoxicillin (Fix Mox), cephalexin (Fix Flex), metronidazole (Fix Zole) and doxycycline (Fix Doxy), plus ciprofloxacin, penicillin, azithromycin, clindamycin and SMZ/TMP, in 250 mg and 500 mg strengths where available. They are sold for aquarium use only: not for human use and not for food-producing animals.

How to use aquarium treatments responsibly

  • Check the water first. Test ammonia, nitrite and temperature: many symptoms come from water quality rather than an infection.
  • Use a hospital tank. Treat sick fish in a separate quarantine tank where possible, and remove activated carbon from the filter during treatment.
  • Follow the label. Dose as directed on the product label and finish the full course, even if the fish look better sooner.
  • Ask your veterinarian before treating pet birds, and before starting any new medication or supplement for dogs, cats, horses or livestock.
