I dont understand what your asking? Is something wrong with the fish?
Im going to go out on a limb and say you my be experiencing a tank crash, your fish do not seem to be doing well at all, one already dead and another that may be on its way out. Im sorry to say, but in all honesty I think you have jumped the gun with stocking your tank and I dont think your tank has fully cycled, thus causing problems with the livestock. This is one of the biggest issues in the saltwater community IMO. You absolutly have to wait for the tank to be ready for live stock, and it takes some time, and then slowly add it, otherwise you blow the bio load.
