Cephalexin is a cephalosporin antibiotic effective against many gram-positive and some gram-negative bacteria. Fish Flex Forte contains a higher concentration of cephalexin than standard Fish Flex, making it a stronger treatment option. This is beneficial for infections that haven’t responded to standard cephalexin or when treating larger fish that require a higher dose.

Common Fish Diseases Treated with Cephalexin (Fish Flex Forte):

  • Severe cases of fin rot, tail rot, and mouth rot
  • Stubborn or deep body ulcers and skin lesions
  • Other external infections caused by susceptible bacteria requiring a higher dose

How to Use Fish Flex Forte (Cephalexin):

  • Dosage: Follow the instructions on the product label carefully. Dosage is based on the volume of water in your aquarium. Because this is a higher concentration formula, accurate dosing is especially critical.
  • 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. Cephalexin will not be effective against viral, fungal, or parasitic infections.
  • Monitor Water Parameters: Cephalexin 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.
