Dead Fish

If he's only 1" long and you have lots of crabs and scavengers then they'd probably eat it before there's a spike in the nitrates. If I put any meat in my tank, then my chocolate chip sea star is on the move in seconds.
 
It is always a good idea to try and figure out why your fish died though.

Did you cycle your tank with that fish or did you add him afterwards?
