Penicillin is an antibiotic primarily effective against gram-positive bacteria. This means it has a narrower spectrum of activity compared to some other antibiotics, making it most effective when the specific type of bacterial infection is known.

Common Fish Diseases Treated with Penicillin (Fish Pen):

• Some forms of fin rot and tail rot (when caused by gram-positive bacteria)
• Certain skin ulcers and lesions
• Other infections caused by susceptible gram-positive bacteria

How to Use Fish Pen (Penicillin):

• Dosage: Follow the instructions on the product label carefully. Dosage is 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 caused by gram-positive bacteria before using penicillin. It will not be effective against gram-negative bacteria, viral, fungal, or parasitic infections.
• Monitor Water Parameters: Penicillin can affect the beneficial bacteria in your filter. Monitor ammonia, nitrite, and nitrate levels closely during treatment.
• Consult a Veterinarian: If you are unsure about the diagnosis or treatment, consult a qualified aquatic veterinarian.
