I'm on day 3 of the Maracyn and Ich-X treatment, no change so far. She has been in a quarantine tank for over a month. The fin damage was there when I got her, guessing it was from being the only female in a tank with 30+ males. The guy I got her from said the tail was healing and I had her for a month and it looked like it was. It started to get worse when I had a male in with her and he probably stressed her out.
I live in a rural area so getting a microscope or a vet. to look would probably be difficult.
