Dropsy

[kuatto]

Dropsy
Cause: bacteria that can only survive in "cold" water (cold to tropical fish).
Cure: Maracyn-Two
Effect: Swim bladder pain, making this disease easy to mistake for swim bladder disease, and puffy, black fins.
How to prevent: Raise temperature above 80oF (but don't fry your fish)

Did a quick search and if caught early,there is a good chance for survival.Lets hope you quarentined him in time and can get some meds to cure him.Will see if I can find more info.
