Marine Velvet or Ich? *PICS*

[apex82]

After my recent crash/poison episode my butterfly and triggerfish have started to get major symptoms for ich or possibly velvet. They have it had it for about 6 solid days now and are still eating. They look uncomfortable, scraping rocks at times and hiding a lot more than usual. Is it possible to have both at same time? Would they be dead by now if it was velvet? It always looks worse when lights come on in the morning. My camera is not the greatest, so symptoms can only really be seen on the butterfly. The trigger has lint type spots/residue on its head and a white film/residue on its fins that are hard to see on camera.

Please help advising if you think its Ich or velvet? Both if possible?

Notice Larger white spots but then thin white coat covering most of body
