I can see cichlidmaster's got this one under control, but plasmah, have you read about cycling a tank? You should do so. If you put all those fish (too many big fish for a 20 gallon IMO) in a week ago, I would bet my next aquarium that your elephant nose died from ammonia poisoning, and your fish are susceptible to ich for the same reason. I'd start doing some serious twice a day water changes if you want to save any of those fish. Just my 2 cents worth.
