This morning I noticed those dark spots on my yellow tang. So he has been in Copper, 2.1, for 6 days. he was eating but was very skittis. I did a water change yesterday and didn’t notice the spots but I didn’t spend a lot of time with them. I usually sit next to the QT tank while working. I also noticed his right fin is tore up a bit, not sure if he got it in the circulating pump. The QT has been up and running for about 4 months and the nitrites were 0 and the nitrates were 20-50 before the 50% water change.
