Using Metronidazole to Treat Aquarium Fish in the US
Metronidazole is an effective antibiotic medication used to treat a variety of bacterial and parasitic infections in fish tanks. Commonly sold under brand names like Seachem Metro, it can cure aquarium inhabitants suffering from hole-in-the-head disease, intestinal infections, cotton mouth disease, and more.
This guide will explore using metronidazole properly to heal sick fish in home aquariums across the United States.
What is Metronidazole?
Metronidazole is part of the nitroimidazole class of antibacterials and antiprotozoals. It works by disrupting the DNA of target organisms, killing both anaerobic bacteria and internal parasites.

How Metronidazole Works
Metronidazole is a 5-nitroimidazole compound. After entering target bacteria and parasites, it is reduced from an inactive form to its active state within the organism.
The activated metronidazole releases reactive molecules that disrupt DNA and inhibit cellular processes. This either kills the pathogens directly or prevents their replication, curing the infection.
Metronidazole has a wide safety margin for fish and is selectively toxic against anaerobes. With proper use, it does not harm beneficial nitrifying filter bacteria. This makes it an effective medication for US aquarium hobbyists.

With the correct aquarium dosage and careful monitoring, it can quickly restore sick fish back to health. However, misuse can be dangerous so always follow label directions closely.
