Fish Supplies

Shop aquarium fish antibiotics from the Fish Aid Antibiotics range — amoxicillin (Fish Mox), metronidazole (Fish Zole), doxycycline (Fish Dox), cephalexin (Fish Ceph), clindamycin (Fish Clin), penicillin, and sulfamethoxazole/trimethoprim (Fish Sulfa). Fish keepers use these factory-sealed capsules and tablets to manage common bacterial conditions in ornamental fish, such as fin rot, mouth rot, columnaris, and septicemia, in both freshwater and saltwater tanks. Typical label directions dose one capsule or tablet per 10 gallons of aquarium water — always follow the directions printed on your bottle. Every order ships from the USA within 1–2 business days with tracking, and unopened items are covered by 30-day returns. For ornamental fish only; not for human use or animals intended for food.
