Can a fish recover from dropsy?
Dropsy is not easily cured. Treatment is geared toward correcting the underlying problem and providing supportive care to the sick fish. A broad spectrum antibiotic specifically formulated for gram-negative bacteria is recommended, like Mardel Maracyn® 2. Always follow directions for duration and dosage.
Can a fish with dropsy infect other fish?
Because dropsy is a symptom of an illness, its cause may or may not be contagious. However, it is standard practice to quarantine sick fish to prevent spreading the underlying cause to the other fish in the tank community.
