At this point, I have tried so much, I don't know if my poor fish is getting worse because of the disease or the stress.
I moved him to a new tank, with a better filter and after the Epsom salt she appeared to be better, still not eating (over a month now) but since a few days ago, the bloating got completely out of control.
I went to a pet store that claims to know a lot about fish and showed them a picture, they said it is septicemia, which is in itself, terrible and told me to treat with Maracyn-Two.
I started the treatment three days ago and now he doesn't even swim and the swelling, everything seems worse!! His scales were raised a little because of the bloating but now it seems like dropsy all the way.
Please help me figure out what is the best way to keep her as comfortable and healthy as possible at this point, it is so sad to see him like this.
I am posting a picture so you can see him, he was a little less swollen yesterday, but this is taken as I write this.
Thanks for all your comments and help.
