Last few weeks I had a ich out break so i removed all fish to a QT and used copper treatment in the QT. After the 6 weeks I put my fish back to my display tank(all ich seems gone). My purple tang got HLLE
which got better really fast after the water quality went back up(My QT is lack of filtration and 10% water change per day seems not enough for a 33g QT)
Now I found small black dots on both of my percula.The spots are way bigger than ich and doesn't looks like anything stick up from the grill.
There are about 3-4 spots on the body also tail.Both fish seems eating well, swimming well and didn't show sign of any problem.(at least for the 3 days out of the QT). Do u think it might just be some scratch that start healing?The funny thing is for one the fish the black spot only apeared on one side.I am not sure about the other.
Anyone might give at least some hint or direction for me to go find my answer?
