help dying fish

I bought a yellow tang two days ago and now its dead, I had a breakout of something about 7 months ago and all but one clown died, corals and all, I had water parameters checked and everything was fine and it is fine now, i then took out all the water, washed off the live rock, put new crushed coral in the bottom and let it cycle again, it is up and running again with two clowns and a goby in it, they have done fine ever since I put them in there, but when I put a bigger fish in there it dies in a couple days, I dont know whats happening, should I take out all the live rock and replace it? I am wondering if it is carrying some kind of disease in it? I have coral in there again and it looks to be doing pretty good... could i have a diseased coral killing the bigger fish? This is the second tang i have lost lately and they were healthy when I bought them, I just wake up and they are dead. Can anyone help?

Not to be terribly blunt, but stop buying tangs.

You're tanks aren't big enough to support larger fish, especially tangs, which are very disease prone, require quarantine and need a 120g or so to really thrive.

As already noted, your tank is far too small to support a tang. Here is some more information for you:

I hope you washed your LR in salt water, not fresh.
Are you quarantining new fish? if not you could be importing ich: read the * thread above on that ailment.
Tangs have an extremely high oxygen requirement. None of your tanks is large enough to accommodate one of these open-water, fast-swimming fish, and if you do not have a potent skimmer with high aeration, and probably a fuge, the water could be so oxy-poor that could be your reason for demise. You need a 75 g tank, ideally with a sump, 140g-rated skimmer, and fuge with cheato, to keep a yellow tang successfully.

You really should stay to goby-sized fish in those tanks: blennies, gobies, smallest jawfish, one firefish (they hate each other). Coral diseases don't affect fish. That's not an issue.
