Also I had an old platy die not to long ago that I posted about on another forum. It didn't have this dropsy but it showed similar signs. It's tail began to fray. The clear edge that holds three tail together per say, just withered away. So the tail was just all frayed and not attached. I tried everything for it. Then it's spine became curved and it finally died. No idea what it was. I just noticed this ones tail today starting to do the same thing. It's not fin rot. Looks nothing like it although I know my explanation makes you think that. Any ideas? My med for dropsy still hasn't came yet.
