Dropsy in Fish: Symptoms and Solutions

Dropsy is a condition characterized by abnormal swelling of the fish's abdomen, often causing the scales to protrude outward like a pinecone. It is usually the result of an internal bacterial infection or organ failure, rather than simple stomach distension.




Symptoms


Visibly swollen abdomen

Protruding scales

Lethargy and loss of appetite

Swimming difficulties



Treatment


- Immediately isolate the fish to prevent the spread of infection


- Promptly improve water quality


- Use effective antibacterial medications to treat the root cause of the condition

In the "Treatments and Supplements" section of the Betta Bite website, you can find potent medications designed to treat the bacterial infections that cause Dropsy symptoms—such as API Melafix, Seachem Kanaplex, and eSHa 2000 (combined with eSHa Exit).




Tip: Do not keep the affected fish in the main tank until it has recovered; isolating it helps reduce stress on the entire aquarium environment.
