Smelt, cisco and herring are all about as good, and you can usually find one or the other it the bait store, with smelt also being available as mentioned at grocery stores.
I use deadbait exclusively when I fish pike with tip-ups through the ice. Any of the three are excellent. I vary the depth, generally running one bait about a foot off the bottom and the second about half way up the water column.
