Another update, so far the fish still seems to be getting better. I'm pretty sure the lump is gone and hasn't returned yet and her prolapse hasn't returned either. She's still getting twice daily epsom salt baths and is still in the quarantine tank. She's starting to eat again too, it looks a bit more difficult for her though, I tried to give her blood worms and she went over to eat them but couldn't seem to get them in here mouth, however she can eat small flake food and isn't spitting it back out.
How long do you think I should keep her in quarantine?
