A friend in Ohio having trouble he’s is wanting a second opinion on what this is, he’s not a newbie. These guys are in qt now one died last night. He has had them for about 4 days they looked good when they arrived except the 1 but not like it was near death.
thanks

The last 2 pics, I am not seeing anything. How is this reefer QT'ing? The 1st pic I am not sure as it doesn't look like Ick or Velvet. I always start from day 1, with frozen food soaked in Focus and GC to help with internal parasites.
