Aquarium Metronidazole 500 mg

Aquarium Metronidazole 500 mg is an antibacterial and antiprotozoal medication used to treat various infections in freshwater and saltwater fish. It is effective against a range of parasitic and bacterial infections, including Hexamita (hole-in-the-head disease), Ichthyophthirius (Ich), and other protozoan infections. Metronidazole works by disrupting the DNA of microorganisms, ultimately killing them and preventing further spread of infection.

Uses:

• Hexamita (Hole-in-the-Head Disease) in cichlids, discus, and angelfish
• Ich (Ichthyophthirius multifiliis) and other protozoan infections
• Gill and skin infections caused by anaerobic bacteria
• Internal parasitic infections affecting the digestive system
• Secondary bacterial infections in fish

How It Works:

Metronidazole interferes with the DNA of harmful microorganisms, stopping their ability to multiply and spread. This helps eliminate infections and restore the health of aquarium fish. The medication can be administered through food or water, depending on the severity of the infection.

Dosage & Administration:

Method 1: Adding to Water

• Dose: 250–500 mg per 10 gallons of aquarium water
• Frequency: Every 24 hours for 3 to 5 days
• Water Changes: Perform a 25% water change before each new dose

Method 2: Adding to Fish Food (Recommended for internal infections)

• Mix 500 mg with fish food
• Feed once daily for 5–7 days

Common Side Effects:

• No significant side effects are commonly reported in fish
• Some fish may show mild lethargy during treatment
• Overuse may lead to bacterial resistance

Precautions:

• Remove activated carbon from filters before dosing, as it may absorb the medication
• Do not overdose, as excessive medication can harm beneficial bacteria in the aquarium
• Ensure good water quality and proper aeration during treatment
