Looks like ich to me.
Yup.

If they are persistent, they are not ich.
^love those little fish. The third pic def looks protruding out.
Its been one week its spots are gone and no sign of reoccurring yet. One different aspect compare to ich i have seen before is after the spots vanished they left a scar on its body. Its a bit like after pimples on our face are gone they leave a scar . It never shows any kind of behavior like twitching or rub against objects, no sign of rapid breathing. All other fish have no spots come up. I am really puzzled what the hell were these lumps.
I feel that it was ich (cryptocaryon irritans); they should magically reappear in the next life cycle.
Its been 7 weeks now since i posted this fish. During this period of time there is no any suspicious white "lump" reappeared nor any parasite associated behavior. None of the other fish show any ich as well. Is it long enough to say that those suspicious dots were not ich afterall?
