This female guppy just today started acting listless the others are all beating up on her.. after looking at her I wonder if she's starting to get ick (see pic) I have been battling a high nitrite spike in the tank for a week and a half now (previously made a post on this). I do 50-75% water changes a day and it still doesn't seem to be slowing the nitrite down. I even went without feeding for a day to see if that would help and it didn't. No doubt this has stressed her out. I have ick treatment but I also have tiny fry in a fry cage in the tank so I'm not sure if I can use it or what really to do at this point.
