my opinion is if you want to fish with tip ups for perch, use fatheads for bait, small to med/small,(usually tiny to begin with). fish in 40 foot of water and fish it deep to start. then work your way up from the bottom until you find them. then as you would with a jig pole follow the school with your tip ups if you feel like moving them around or leave them be, I usually have them come back for rounds 2 and 3 through out the day.
