Fish Amoxicillin – Treating Dropsy (Edema)

Dropsy in an aquarium goldfish: Dropsy is a symptom where a fish’s abdomen swells and scales stick out like a pinecone due to internal fluid buildup​. It often results from bacterial infection (e.g. Aeromonas) causing kidney failure and fluid retention. Fish Amoxicillin is a broad-spectrum antibiotic that can help eliminate the underlying bacterial infection in cases of dropsy​. By targeting gram-positive and some gram-negative bacteria, amoxicillin can reduce internal infection and swelling, giving the fish a chance to recover.
