Penicillin Fish and Bird Antibiotics

Keep your aquarium fish and birds healthy with our trusted penicillin fish antibiotics and effective bird antibiotics. Penicillin remains a classic, highly effective antibiotic widely used by aquarists and bird keepers to quickly control bacterial infections. Conveniently available without a veterinary prescription, it offers immediate, reliable treatment when your pets need it most.

Penicillin for Fish: Fast Treatment of Aquarium Diseases

Fish commonly encounter bacterial infections caused by stressful conditions or poor water quality. Penicillin quickly targets and treats:

  • Fin & Tail Rot: Accelerates healing of damaged fins and prevents further deterioration.
  • Open Sores & Ulcers: Promotes fast healing and prevents bacterial complications.
  • Mouth Fungus (Cotton Mouth Disease): Rapidly clears white, cottony growths around the mouth.
  • Bacterial Gill Disease: Quickly resolves infections that cause swollen, inflamed gills.

For effective aquarium treatment, dissolve one 500 mg tablet per 10 gallons of water daily for 5–7 days. Always remove activated carbon filters during treatment for optimal results.

Penicillin for Birds: Proven Infection Relief

Birds frequently suffer from bacterial infections that penicillin efficiently treats, including:

  • Respiratory Infections: Quickly alleviates sneezing, coughing, nasal discharge, and difficulty breathing.
  • Digestive Infections: Controls diarrhea, lethargy, dehydration, and loss of appetite.
  • Wound & Skin Infections: Promotes rapid healing of infected cuts, abrasions, and foot sores.

Administer penicillin by mixing it into drinking water or food daily for 7–10 days. Birds typically show marked improvement within several days of treatment initiation.
