Ok ... so for the last 2 days she's been going to the bottom and just like lying down there (as if she's dead.) Obviously she's been breathing ... but the miraculous part is that she rests for 2 hours then gets back up and somehow reaches the top (and goes to the surface to get air maybe?) And then after about a minute or so she's goes back down to rest.
This has been happening for the last 2 days ... but every time she goes down she stays there for even a longer time. I had added the carbon in the filter, because I felt there could have been a lack of oxygen. Anyway, I removed the carbon ... and took the advise that you guys gave me. I brought her up to the surface with a net (but didn't take it out of the water), and kept poking at the fungus with a paintbrush. After 5 minutes, half of it finally came off. The fungus is significantly smaller now .. and she's gone back to the bottom.
I added the medication, and im hoping that she can make a miraculous recovery. Hopefully its not to late ... she a real fighter.
Thanks for all the help everyone
