Perhaps an infection? Normally when you treat parasites there is a secondary
infection where the parasite was attached when you kill off the parasites
(it's more or less an open wound).

I've been treating my fish for anchor worms and ich. The parasites seam to
be
gone, but now I'm noticing some black dots on some of the white fish and 2
lumpy things that appear to be under the scales of one fish. Are the black
dots
scars from the parasites? What are the lumpy things? Thanks in advance for
any
advice. Judi
