In the black bar on the fish there is a growth, kind of like a wart. The growth is pale in color and very round at the end. I am trying to find out what it is and am asking y'all for any ideas/advice/help. The growth protrudes ~1mm from the side of the fish. I initially treated for ick when it was just a small spot, but that didn't seem to help. I have not added any new fish, plants, wood, gravel, etc. for quite sometime.
