Hi, everyone. Iām not exactly new to fishkeeping; however, I finally have a tank again after 18 years of break from the hobby. Iāve just started out again with a new cycled tank and some angelfish I purchased from Petsmart. After putting them into my aquarium I noticed something strange looking on one of the angelās fins. It appears to be Ich, but it doesnāt have the classic āsalt grainā look to it.
Itās also been on the fins, in the same place without change, for 5 days. My gut is telling me to treat the entire tank now to be safe, but these spots almost have an egg-like appearance. One friend believe itās Ich but isnāt confident. Is this really Ich? Any information is appreciated. Thank you.
