The white bump is similar to the beginning pics of Goldie's, but does not look, at this point, like it could burst and there is no redness surrounding it or in it at all. it just showed up overnight and looks like a white zit you could pop.

Water params are the same as when I started this thread in the emergency room. He is eating normally and poop looks normal. There is still a slight curve to the spine, but better than previous. He does not seem lethargic. I have not treated anything since I last treated with kana about 2 1/2 months ago. I have a 12 gallon Eclipse tank and now only 1 platy, 1 balloon molly, 1 otto, and 2 cory cats are left.

Should I treat with anything?

Thanks!
