They were moving around the tank and even eating a bit. Then woke up yesterday morning to find them all dead.
I am hoping for some insight into what might have killed them all. They didn't have any spots that looked like ick or velvet etc. All the corals and inverts look fine. Just the fish are dead.
My only idea is that maybe the oxygen levels dropped too much at night when all the photosynthesis stopped and everything in the tank was using oxygen up. I have good water circulation with a koralia nano and a HOB aquaclear filter splashing water back in which I assumed would be enough water movement to keep the water oxygenated. Salinity was 1.026 and ammonia, nitrate and nitrites were all 0. pH is about 8.2.
I don't want to get any fish again until I have some idea what might have done this. Is there any possible contamination in the tank that would specifically kill the fish and leave the inverts unaffected?
Thanks in advance for any insights,
Ron

The answer is very simple. You put too many fish in your tank at the same time and put the bioload out of order. At the very minimum in a tank your size I would only put one fish every two months.
BTW I would also not get a gramma as they are too aggressive in a small tank. I would put the orange last like 6 months from now to give your sandbed a chance to grow lots of critter.
