Hi y’all! Need all the advice I can get Noticed these spots on my clown yesterday, seems like it may be Ich? I may be clueless but I was under the assumption that they contract ich from adding new fish but my tank has been stable and no new additions in a long time. If anyone has more insight on this I’m very confused with the mixed information online and in my marine books. Also, if anyone has any experience with the Fritz coppersafe I need any and all advice on the best way to treat with that product or if I should purchase something else? Thanks so much in advanced! Also, I have quarantined both of my clowns in separate tanks at this time.
