I can see 2 tiny black spot on his body must be black spot. I just want to know will that be alright if I leave it for the time being? I don't have a QT and don't want to set up one. Also I don't want to catch it as he is so fast and I don't mess around with my rock works.
If I leave it alone in the main tank and if the black ich fell off will it come back to haunt the fish in future? And will ocellaris clown and chromis get them easily?
If the yellow tang is healthy in future and there are still presence of black ich in the tank will he get that again?
I am thinking of dosing copper right into the main tank. I am thinking of doing this FOWLR
tank anyway. Will not have any kind of coral and invert at all. But will get some blennies and gobies to do the cleaning instead.
