Thomas Labs Fish Sulfa Forte (Sulfameth / Trimethoprim)

Fish Sulfa Forte (Sulfameth/Trimethoprim) is a high-concentration antibiotic formulation designed to treat severe or persistent bacterial infections in aquarium fish, or for treating larger fish. As part of our commitment to providing comprehensive fish care solutions, we offer Fish Sulfa Forte within our Thomas Labs Fish Antibiotics category. For a broader selection of fish health products, please also see our Fish Medication category. At Thomas Labs Pet, we strive to provide quality medications for various fish health needs.

Fish Sulfa Forte contains a combination of sulfamethoxazole and trimethoprim (SMZ-TMP). This combination is synergistic, meaning the two drugs work together to be more effective than either drug used alone. The “Forte” designation indicates a higher concentration of these active ingredients, making it a more potent treatment option.

Common Fish Diseases Treated with Sulfameth/Trimethoprim (Fish Sulfa Forte):

  • Severe cases of fin rot, tail rot, and mouth rot
  • Stubborn or deep skin ulcers and lesions
  • Bacterial hemorrhagic septicemia
  • Columnaris infections that are not responding to other treatments
  • Other bacterial infections requiring a higher dose of SMZ-TMP

How to Use Fish Sulfa Forte (Sulfameth/Trimethoprim):

  • 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. Sulfameth/Trimethoprim will not be effective against viral, fungal, or parasitic infections.
  • Monitor Water Parameters: Sulfameth/Trimethoprim 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.
