OK so you realize you rushed the stocking of your tank and didn't take precautions that you should have. BUT, when I was reading the fish list, I assumed you at least a 180 or bigger. That was WAY too many fish for a 90!! The clown tang is aggressive, the powder blue is very sensitive, the angel needs a bigger tank even without all the other fish. The Kole was fine and the clowns, of course. But, unless you have some serious filtration and do water changes a LOT, like twice a week, you were going to have losses.
Research more and have more restraint on stocking and you will have more success.
