Seachem MetroPlex | Aquarium Fish Treatment | SMA

Seachem MetroPlex is an aquarium fish treatment containing metronidazole and is formulated for treating certain protozoan parasites and anaerobic bacterial diseases in ornamental fish. It can be used in both freshwater and marine aquarium systems and offers flexibility in how the treatment is administered. According to Seachem, MetroPlex can be dosed directly into aquarium water or incorporated into a medicated food mix for fish.

MetroPlex is commonly used for conditions such as Ich (white spot), Hexamita/Spironucleus-related infections and Velvet, although similar symptoms can occur with different diseases, so identifying the likely condition before treatment is important. Seachem also notes that MetroPlex can be used for both internal and external infections depending on the delivery method. When used as a medicated food mix with Focus, it can be particularly useful when targeting internal parasites while limiting medication entering the aquarium water.
