All my fish are dead

[corper]

I got up this morning only to find all my fish dead . I don't know what happened? I turned out the lights last nigh at ten, Went down to turn them on this morning at six and they were all dead. My corals are fine though. No power went out, temp is fine and water quality looks good. The only fish to survive was a damsel, sleeper goby, spotted watchman, one cleaner shrimp (not looking good) and both my starfish. The sleeper goby looks like he has some red by his gills and on his fins. But he seems to be ok for now. I lost my tangs, the rest of my damsels and clown fish. I'm so ****ed of right now . How could this happen? I moved two weeks ago, but the fish haven't shown one sign of distress. I kept them in their old tank water in a 33 and half the live rock. In alll honesty, they were actuall doing better. I just don't get it . Lucky for me I gave all my SPS and LPS corals to someone to look after. I kept my softies and leathers and their fine. All my crabs and snails seem to be intact. The worse part is that I planned on moving them into the 72 today. Should be much easier now (not funny) .
