When you first posted the question, my thoughts were NO WAY do I want to try another one. Actually I was so depressed that I was wondering how I could just "get out of the hobby" for a while because the death of that fish took a toll on me. I don't get attached to my fish like I do with other pets like cats and dogs, probably because you don't really interact with fish too much. I don't name them, just call them their common names. On the other hand, I feel a huge responsibility to give the absolute best care I can for everything in my aquarium, especially the fish.
I made several major mistakes with this fish and what kills me inside is all the mistakes I knew better. I knew I should have QT'd the fish, but was just lazy. I knew there was a very very strong possibility of my potters angel attacking the tang, but I risked it at first and within just a minute of being placed in the tank a lot of damage was done. This particular fish was just shipped via 2 day air, not overnight for some reason, and then acclimated once when it was received, then again when I got it home that night, then placed into a tank and immediately attacked. Way to much stress and wounds from the start. I tried to do the best I could at the time, moved the tang to what I thought was a better environment, only to learn it wasn't. The next day (I got the fish home around 10pm and in the tank at 11pm) I setup a Hospital tank to do things properly at 11am the next day, only 12 hours after the fish first went into one of my tanks, but the damage was done and it was too much from that point on for the tang to handle. If I had done it correctly from the start I am sure it would have been a good fish.
But now, after several hours to go through the emotions, I am feeling better and now I think I probably will try another one when I can find it. Took me 10 years to find this one locally. I can probably find one online though, but getting one from one of the major reputable online places is difficult. Only seen them at a couple sites that I know nothing about.
