Fish Zole 500 mg 60 Tablets – Metronidazole Fish Medication for Aquarium Use

Fish Zole 500 mg Tablets contain Metronidazole 500 mg, a powerful antimicrobial medication formulated to treat protozoan and anaerobic bacterial infections in ornamental and aquarium fish. Suitable for both freshwater and saltwater systems, Fish Zole is commonly used to manage internal parasites and conditions such as hole-in-the-head disease, hexamita, and certain anaerobic bacterial infections.

Metronidazole works by disrupting DNA synthesis in protozoa and anaerobic bacteria, preventing their replication and helping infected fish recover. Its targeted mechanism makes it especially useful for infections affecting the digestive tract, gills, skin, and internal organs.
