Disappearing albino shark?

I've had my tank set up for about 7 months now. I have a 29 gal with 1 albino rainbow shark, 2 angel fish, 3 mickie mouse platies, 5 gold danios and an albino bristle nose sucker. Today my albino rainbow shark disappeared. I've looked everywhere, even moving a couple rocks just to make sure he didn't get stuck. I've looked in the filter, in my sink and on the floor (where he would have fallen if he jumped) but cant find him anywhere! He was pretty much the biggest thing in there and had been in there the longest. Is it possible the 2 angel fish ate the whole thing overnight (not leaving any bit left)?? I just can't imagine where he went :-(
