So I've had new tangs in my quarantine for a little over a week now (Yellow, Sailfin and Blonde Naso). The Yellow Tang who died a few days ago (which seemed pretty sudden as its behavior seemed normal the night before). Then yesterday I noticed subtle black spots all over the blonde naso tang. It had to be really close to the glass to see them. After researching online and concluding it was Black Ich I treated the tank with Prazipro as directed on the bottle last night. This morning there are WAY more black spots, they are obvious from across the room, and they have also appeared on the Sailfin.
Is there something else I should do to treat this? I definitely was not expecting it to get worse after treatment.
