  • Protozoan parasites: Hexamita (hole-in-the-head disease), Spironucleus (whirling disease), Cryptocaryon irritans (white spot disease)

  • Anaerobic bacterial infections: Gas пузырь disease, fin rot
  • Skin conditions: Ulcers, fin erosion

Can I Use Human Metronidazole for Fish?

While human metronidazole may work in a pinch, it’s not recommended for several reasons:

  • Dosage inaccuracies: Human formulations are typically much stronger and can easily overdose sensitive fish.

  • Antibiotic resistance: Overusing human antibiotics can contribute to antibiotic resistance in fish and humans.

Alternatives to Metronidazole:

In case of allergies or resistance to metronidazole, consider these options:

  • Kanamycin: Effective against bacterial infections, but can harm sensitive fish.
  • Ciprofloxacin: Broad-spectrum antibiotic, use with caution due to potential antibiotic resistance.
