bacterial infection

[jodi.con]

i recently purchased a pearlscale goldfish, after quarantining her i added her to my main display tank. which was good until i noticed aggression between her and my larger male fancy goldfish. after noticing the aggression i spotted white spots at the bottom of the tank that i mistook for eggs. they were instead my female pearscales, scales. i immediately separated them, but it was already too late as a lot of her scales were already bumped off. since this incident i’ve been treating her with maracyn, to help prevent a bacterial infection. i’ve since noticed a white/transparent  stringy coating is coming off of her. she also hasn’t been very active. this is my first time keeping pearlscales, and i haven’t been able to find much information. if anyone could give any advice i would appreciate it so much!!!
