There is a lot wrong with what you wrote here and you're learning some hard lessons. First, your saltwater tank is way too new for a fish never mind how many you put in there before it cycled. Secondly you have to research what fish go in when. you can't throw a tang into a brand new 40 gallon tank and you'll be hard pressed to ever find a tang happy in a 40. So now you have a serious issues because ich is in your tank now. If a fish survives you should leave it there by itself for quite some time now. ich has about a month cycle, google the marine ich cycle to understand. if you add a fish with ich still in the water it'll contract it and start over again. really you should leave your tank empty for a couple of months but most people just setting up a tank decide not to follow this as they've just spent a lot of money on a glass box with rock. It sucks cause its not like a fresh water tank where you add blue medicine and ich goes away. Marine ich is super tough and you have to let it dye out or if you want to kill it with coper or hyposalinity you'll knock out whats living in your tank. So now you have to make some choices about how you're going to deal with this. Some people just leave it, you may have a clown survive and you can just enjoyhim for acouple of months and others go the kill it route. i guess it depends on what you have to loose at this point.
Once you're in the clear do a lot of research about your tank and what you can do to keep it thriving. Read about cycles and water parameters. Find out what fish are cool in a 40 gallon and what will stress and die. Its complicated and can be overwhelming but once you get it, its pretty rewarding....
