How to Use Fish Doxy (Doxycycline):

  • Dosage: Follow the instructions on the product label carefully. Dosage is typically based on the volume of water in your aquarium.
  • Water Changes: Perform a partial water change (25-50%) before starting treatment and between doses.
  • Treatment Duration: Complete the full course of treatment as recommended on the product label, even if symptoms improve.
  • Quarantine Tank: It is highly recommended to treat infected fish in a separate quarantine tank to avoid disrupting the biological filter in your main aquarium.

Important Considerations:

  • Accurate Diagnosis: Ensure the fish’s illness is indeed bacterial before using antibiotics. Doxycycline will not be effective against viral, fungal, or parasitic infections.
  • Monitor Water Parameters: Doxycycline can affect the beneficial bacteria in your filter. Monitor ammonia, nitrite, and nitrate levels closely during treatment.
  • Light Sensitivity: Doxycycline can be light-sensitive. It’s best to dim the aquarium lights during treatment.
  • Consult a Veterinarian: If you are unsure about the diagnosis or treatment, consult a qualified aquatic veterinarian.
