    Hi fish people,

    I noticed one of my koi (who jumped out of the water about a week ago) developed a black spot kinda under his skin near the tail, and the scales around the area got a little fuzzy. What I mean by that is the scales are not shiny and smooth anymore and gotten kinda like frosted glass and the skin underneath appears to be pink. Is this a bacterial infection? Also, he seems to have ich on the head.

    Attached are the pictures I took of him in the hospital tank. I tried to get better pictures but these are all I could manage. Please help me, thank you guy so much.

    Could be a protozoan like chillodonella

    could it be carp pox?

    plus I've been treating the tank with Seachem paraguard for a couple of days and it doesn't seem to be working

    okay, then it isn't that

    the white spot on the head is too big for ich right?
  6. DoubleDutchFishlore LegendMember

    Yes and paraguard should have handled that.

    any idea how I should treat this thing?

    Could the black spots be carp lice maybe ?.

    I don’t have a lotta experience with koi, does carp lice appear to be under the scales covered by almost frosted skin? I know the pic is pretty bad but I just can’t get a good shot. The fish is eating normally and behaving pretty calm.I upped the temperature today and he’s pooping like a champ...
