Achilles death

[matt 76]

Just wanting feedback on what filthy creature of a disease would do this? This fish was quarantined in cupramine for 4 weeks when this showed up 3 days ago. I currently am in the process of refilling my HT with fresh saltwater and am about ready to do paragaurd. I have a good idea of what it is but I am wanting other users input before I influence their decision. Any other info needed let me know.
The spot where the flesh is missing was blackish and slightly inflamed before it just fell off
The red you see was a glare from the camera.

Urenoma will do this but this is by far the worst case I have seen especially in 3days time

Looks to me like a burn from a heater

I suppose this could have happened but being submerged in water, would the heater be capable of putting off this much heat? Maybe I need to move the heater to the top of the tank and position sideways. It has suction cups.

This was my thought. I have what I thought was marine velvet killing off my fish. So I caught all of them out of the display and put them in a 55 gallon HT with cupramine. They were in the HT for about 4 weeks. This should have been plenty of time to eradicate velvet or ich. Although they were going to have an additional 4 weeks in cupramine until today. I have read many many threads on this site and many others. Brook was the conclusion I came up with. Really a bad deal. Poor fish was perfectly healthy and chowing down on nori 3 days ago.

Sorry for your loss, it's always thought when fish are doing fine and then something like this happens

How carefully were you monitoring the copper dosage?

I was checking it with a seachem test kit. I tested it after I dosed. According to seachem, unchealated copper won't leach out or dissipate from the system so unless you do a water change you shouldn't have to replenish any cupramine.

I was at about .4

Evaporation/top off? I am asking because if the copper level dropped below therapeutic levels, it will mask parasites rather than eradicate them.

I was under the impression by the seachem statement that it stays in the water it would not evaporate... I did however perform 50% water changes once a week and at that point added more cupramine. My evaporation rate was very minimal maybe 8 cups of ro water every 2 days.

Update;
My purple, powder blue, blue hippo, vampire, naso, and yellow tang are eating well today. Their colors are also amazing. So far no problems with starting the paragaurd treatment by seachem. One question I could not find a definite answer about was wether or not I can run carbon in the HOB filer? I just put it in relying on their statement on the bottle being filter safe? Am I interpreting this wrong?
