About 4 days ago both my boys started acting sick. They wouldn't eat and hardly swam around at all but didn't have any actual physical symptoms that I could see so I moved them both to half gallon QT bowls to watch them and do 100% daily water changes instead of every other day like I normally do. In no time Valentine was better but Romeo was still very lethargic and wouldn't eat but still no other symptoms so I didn't know if I should treat with AQ salt or Epsom and just continued with clean warm water(80*). Today I woke up and he is barely moving at all and staying up at the top with his nose at the water line, he is extremely bloated and has raised scales like a pine cone.. yesterday he was neither bloated or had pine conning. I am about to do a water change and add Epsom 2 tsp to a gal but I'm worried that its to late and he will die because of me not seeing any obvious symptoms :(
Does it normally happen this way? And is dropsy or whatever caused it normally contagious?
