      Black spots on fins, juvenile fish

      What might this be?
      Fish is behaving normally.
      2 other fish in same tank show no symptoms.
      How should I treat?

      Detail is not clear enough to see. It could literally be coloration forming. Does it look like there are parasites attached or....?

      Andrea is right, can't tell from photos, can you take clearer photos (I know they move all the time). Also some species during youth will show tiny black spots and that is just genetics, not saying that is it though. If the area turns red around area, than most likely parasites or fish rubs against pool sides and bottom.

      Daily water tests are good. I did have a nitrite problem, but that's resolved. All water parameters nominal.

      I am familiar with "cotton" fungus it's definitely not that.
      This tank did have a cotton fungus issue a while ago. But I treated with bay oil and water changes and it went away. It was in the tank but I never saw any on the fish. Anyway, that's been cleared up for quite a while now.

      It's also not ich.

      I've searched google for similar symptoms in images, but can't find anything.
      Most fungus infections are white.
      I will treat the tank with bay oil for fungus again and see if that helps.

      No red areas. I'll try to get a better photo. He does do some flashing, but not excessive.
