Fish Mox 500 (Amoxicillin) – 500mg Fish Antibiotic Capsules

Fish Mox 500 (Amoxicillin) is a trusted antibacterial treatment used to manage common bacterial infections in aquarium and ornamental fish. It is widely used in both freshwater and saltwater systems where visible signs of infection require a reliable and structured treatment approach.

This broad-spectrum fish antibiotic works by targeting harmful bacteria responsible for tissue damage, internal infections, and external lesions, helping stabilize affected fish and support recovery when used correctly.

Common Conditions Treated

  • Fin and tail rot
  • Body ulcers and open wounds
  • Red streaking and hemorrhaging
  • Gill infections
  • Dropsy (bacterial-related swelling)
  • Mouth and skin infections

How Amoxicillin Works in Fish

Amoxicillin works by interfering with bacterial cell wall formation, preventing bacteria from surviving and spreading. This helps reduce infection pressure in the aquarium and allows the fish’s natural recovery process to take over.

Dosage & Treatment Protocol

  • Use 1 capsule (500mg) per 20 gallons of water
  • Repeat every 24 hours
  • Continue treatment for 5–10 days
  • Perform partial water changes between doses if needed

Best Practices

  • Remove activated carbon from filters during treatment
  • Ensure strong aeration in the aquarium
  • Monitor fish closely for response
  • Use a quarantine tank when possible

When to Use Fish Mox 500

Use when clear signs of bacterial infection appear, including fin deterioration, redness, swelling, or open sores. Early intervention improves recovery success.
