Please Help Sick Fish

[Lauren Couch]

symptoms:
shiny scales, itching, (no white spots), white tuffs/fuzz patches on body followed by fin rot. what is it and how can I treat ?






I have scaleless fish and invertebrates in the tank so the medications can't interfear with them.
this is how it starts shiny itchy scales and a white tuff/fuzz patches on the body followed by finrot then death.

Aww that's so sad. I know petco has a combo pack of medication for different fish illness.

But I wouldn't do the recommended dose and since scalelless fish are so sensitive, I am not sure the best approach.
