I agree on the cyanide,,,,, and lets all hope all efforts to stop it, work....
The Kole never showed any signs of ich,,,, not a single bit.. In fact, he never showed any signs of anything until that last day.
The powder brown looked perfect in the store, but he had only been there 1 day. I knew it was a risk, but I knew he wouldn't still be there in a few days if I didn't get him, and they won't hold them at this store. When I got him home I acclimated him over 3 hrs and all went well. I put him in the QT and he seemed very active, and I could tell he didn't like that small tank. About 2 days into it, I noticed a couple of small specs on his side, but I didn't want to treat just yet as I was hoping his natural immune system would do the work. He wasn't flashing or anything at this point, but still very very active. On day 4 I noticed him starting to flash against the pvc fittings and such, and there were more white specs on him, so I decided to treat with coppersafe. The treatment went well, and all specs were gone within 2 days and the flashing had stopped. Knowing these tangs don't do well with copper, I didn't want to leave it too long, but long enough to kill the ich. 3 days after all signs of ich was gone, I did a partial water change to dilute the copper somewhat. At this point he still was very active, but some sore spots were starting to develop and some discoloration in patches. Another day later it was worse, so I added some meds for the infections, but it never seemed to help, and the spots got larger. During this whole time he wasn't eating very much,,,,, just a small amount here and there, and he was constantly swimming about and always pretty fast. Sometimes even just in circles or figure 8's, so I know the small tank was stressing him. Within a couple more days the spots had grown and his skin on those spots looked to be rotting. Another day or so and he was gone. He was the first one I had ever had to treat for an infection, and it obviously didn't go well, but I think I would have been better off with a larger QT to start with. He was never scared, would come right up to my hand as I was putting algae on the clip and would never hide, so I think he just wanted more space, and that was adding alot of stress, which definitely didn't help his situation. I don't remember what meds I used for his infection since I am at work now. It was some my neighbor had given me when he took his tank down, but it is for infections and I treated according to it's directions. I can try to look tonight for what kind it was.
