Fire shrimp will take opportunity to eat parasites off of fish. They're just not as proactive at it as skunk cleaners. I had a fire shrimp that took a serious liking to a watchman goby for the longest time and then just not be interested anymore some several months down the line. Followed the fish everywhere. Would not leave his side. Though I never really saw the shrimp pick at him. Both are still alive. This was four years ago.
You also want to check the calcium and alkalinity levels. I'm on the second page and can't see if you had mentioned if this is a reef??? Calcium should be at 450. Alkalinity should be between 2.5 and 4.
Take care of the pH before dealing with the SG. One stress at a time. Double check the ammonia. What brand test kit are you using? Once you are absolutely sure there's no ammonia in the system, then tend to buffering the pH. I'm not familiar with Dolomite, but I do know aragonite can serve as a buffer by dissolving at 8.0, instead of 7.8 like crushed coral. There are powder and liquid marine chemical buffers you can use. Keep the pH from going below 8.0, but be sure the ammonia is down. It is natural for pH to go down when ammonia goes up. This helps keep the ammonia from being toxic. If the pH is rasied before the ammonia is down, you can poison the fish.
I know, this can be a PITA to deal with. Welcome to the hobby There is another use for garlic food soaks and that's to help keep parasites off the fish in case there are parasites. Get yourself a skunk cleaner. They'll live fine with the fire shrimp. They really are more proactive in eating parasites off of lots of things. They can help. I always get a manicure from them when I stick my hand in the tank...LOL. I had a scrape on my knuckle once and they went right for it picking and cleaning out all the nasties of the wound. You have a big enough tank for more than one. A good investment
BTW...Being on the floor of the tank or floating I highly doubt has any bearing to how the fish died. Whether a body floats or sinks depends on the gases inside of that body. Not how the body stopped functioning.
