Copperbands not for me

[sully08]

I guess I should listen and leave this fish to the reef pros. Tried to put one in my 8 month old tank and it died about 7 days into quarentine. Couple months later I tried another one and quarentined it for 2 weeks. He ate Mysis, looked really good, no signs of disease. I put him in my D.T and he was dead in 2 days, no idea why. I heard they were really hard to keep. Anyone had similar problems like this? All tank water tests were good.
