Like all pets, fish get sick. They need treatment, which often includes antibiotics. However, with so many antibiotics to choose from, it can be hard to pick the right ones. Read this guide to learn about the best types of fish antibiotics.

Fish Penicillin

You are probably familiar with some of the benefits of penicillin. It is important to know that fish have their own version of penicillin as well. Please note that fish penicillin should only be taken by fish. Fish penicillin treats flexibacter infections as well as common diseases such as tail rot and fin rot.

Fish penicillin is available in 250 and 500-milligram tablets. You can give your fish 250 milligrams of penicillin for every 10 gallons of water or 500 milligrams for every 20 gallons of water. Treatment should clear up diseases within 5 to 10 days of treatment.

Amoxicillin

If your fish gets bacterial infections often, amoxicillin can help eliminate symptoms and prevent the infection from spreading. Some common diseases that amoxicillin treats include dropsy, red pest disease, fin rot, tuberculosis, and scale deformities. Amoxicillin comes in 250 or 500-milligram capsules. Your tank or aquarium should use 250 milligrams of amoxicillin for every 10 gallons of water.

Metronidazole

Metronidazole treats bacterial and parasitic infections. Some examples of these infections include hole in the head disease and various gill diseases. Fish typically respond well to one 250 milligram tablet per 10 gallons of water for 5 to 10 days. Between treatments, you should do partial water changes. If fish do not improve after five days of treatment, it is important to call a vet.

Ciprofloxacin

Ciprofloxacin treats common diseases in freshwater and saltwater ornamental fish. Some diseases it treats include gill diseases, red pest, dropsy, and fin rot. Ciprofloxacin is available in 250-milligram tablets. You should give fish one tablet per gallon during every 1-2-hour bath treatment for seven days.
