By your description, it could have been dropsy. Without an image or exam though, this cannot be determined definitively. Dropsy is a symptom of underlying illness, rather than a specific disease. Maintaining a clean tank, stable water chemistry and proper environmental parameters will go a long way in prevent illness. Separate any sick fish will keep disease from potentially spreading in the tank.
