A while back one of my male dwarf puffers had what looked like a white pimple on his head but it was there for as long as I can remember. I just got home from being gone for a few days and I noticed his whole head was covered in these white pimples. I've had ick before but this is bigger then ick, plus there has been no new fish in many months and none of the other fish have anything on them.
What do you think?
