Default Most stressful fish I've ever owned

Well its been just over a month since I've acquired my achilles tangs. I currently have one in my LPS tank and one in my sump. Although both are eating nori and swimming around normally, they are both very icky.
I have to say for the past month, everyday I wake up in the morning anticipating or wondering if I will find a dead fish and so far so good; these guys are still alive and definitely toughing it out.
But I'm at the point where I am starting to regret acquiring these fishes just because they are so day by day and just not knowing if they will make it another day or two, or three or whatever. The achilles in my LPS tank was so covered with ick at one point it looked like a swimming ghost. Now most of it is gone but still there and its now its getting secondary skin diseases of some sort. At this time, I just don't know if they will live and if they do, for how long. Kinda sucks....

I just thought I should share with everyone my experience with these tangs so far.
Quick background:
I went to Hawaii on November 8 where I liaised with a local pet store to get some achilles tangs. Six were caught by a local diver in Hawaii and brought to the pet store on a Monday. They varied in sizes from 3 to 4.5 inches (1 @ 3", 1 @ 3.5", 2 @ 4" and 2 @ 4.5"). All of them were in prime ick-free condition when I had them packed and shipped on the Friday. The six fishes were individually packed in LARGE bags, 1/3 bag full newly made IO saltwater that had been aerated for 4 days, the remaining 2/3 filled with pure oxygen. They arrived at my place approximately 15 hours after being packed into the bags. Water temp was about 75 degrees which was excellent for 15 hours of shipping.
2 fishes stayed with me: 4.5" and 4"
4 fishes were sold to locals.

Treatments:
1 achilles was given a FW dip and it died the following day.

1 achilles was acclimatized for and placed into a hyposalinity FOWLR tank at 1.10 ppt. This fish acted normal and it ate nori, mysis, and pellets for about 1.5 weeks when it developed a few specks of ick. The ick disappeared and seemed to have been cured when at the 2 week mark, it suddenly just died. The other fishes in this tank began to die at the rate of one every 3 days and after losing about 8 fishes, the salinity was slowly increased over 2 week period (since the hyposalinity condition was obviously not working properly). The fishes were developing patchy spots of some sort of fungus fuzzy stuff on their bodies. The tank has lost a few more fishes since and its still being monitored. The tank was a 120g with 40g sump, 80lbs live rock and rs135 euroreef skimmer for filtration. Aside from the few specs of ick, there was no signs of the fungus on the achilles before it died.

1 achilles was placed into quarantine tank with a 25 w UV sterilizer and skimmer for about 1 week. Some ick developed and some copper was used in the QT tank. This fish acted very well eating mysis and nori like a pig. When the ick was cured after a week in the QT, it was placed into a FOWLR where it continued to do well. At around the three week mark, it just died.

So that leaves only three of the six which are alive at this time. As I stated, both my achilles seems to be a day by day with ick but otherwise eating and swimming around normally. I didn't give them any dips or treatments, and I'm running ozone at 450 mv and 100 watts of UV.

The third achilles at another reefer's place is not very icky and seems to be doing really well. No dips or treatments and that tank is running 80w of UV.

Conclusion:
Well I can't make any conclusions based on 6 fishes but I will point out the following:
- I had complete control of the way they were packed and the time these fishes spent in bags was kept to a minimal (15 hours)
- they were in perfect condition when they arrived at the store and when they arrived in Vancouver
- of the 6, only three are still alive
- the three that died were given special "treatements" - 1) FW dip 2) hyposalinity, and 3) copper.
- of the three that are still alive, two are very icky and one is OK. At this point, only time can well what will happen with them.
- I had an achilles before that died after a FW dip and I spoke to another experienced reefer in Calgary whose achilles also died after a FW dip. It would appear that achilles tangs are hyper-sensitive to freshwater dips.

So if there was any advice I would give to others about these tangs, I would not recommend getting them. They are probably one of the most beautiful tangs out there but owning one is stressful and even when the best shipping conditions were provided, there is still a high mortality rate.

I will update on my tangs as required.
