Dropsy?

Common Name: Dropsy
Pathogen/Cause: Various organisms (nonspecific), poor water quality.
Physical Signs: Bloated appearence with scales that stick out like a pine cone. Best viewed from above. Dropsy is not really a specific pathologic entity, it is to describe a general condition of fluid accumulation in the internal body cavity, which has many causes. Dropsy usually signals internal infection and multiple organ failure. It can be compared to ascites in humans in end stage kidney failure.
Behavioral Signs: Lethargy, lack of appetite, grave constitutional signs.
Potential Treatment: Unfortunately, dropsy is *usually* incurable and fatal; however, in rare cases, spontaneous recovery may occur. A strong antibiotic such as kanamycin sulfate can be tried, but because it is an internal infection, usually it does little good.
Other Notes: Take measures to improve water quality immediately. Fortunately, it is not highly contagious.
