I have a platy with dropsy. She's bloated, pineconing and the whole shebang. I've tested for everything in the tank she came from and cant come up with anything but liver failure since the water is perfect. PH7.0 no amm/trites and 15trates. She's in hospital tank now and mostly just rests on the bottom though I do catch her swimming around a bit. She's been like this for 3 days now and nothing I have tried has helped her out. She's also not eating. I've tried epsom salts, anti bacterial and anti parasite and nothing seems to help. No other fish seemed effected at all. Anything you can think of I should be doing?
