Yes, the scobies will grow in layer form. Lots of people start peeling off the layers as they grow (super clean hands). Some refer to them as the "mother" and babies. You only need some scoby, and can prune it down. The longer you brew, the thicker the pancake layers will get. When I tossed mine recently it was about 8 inches thick cause I had let it get out of hand. It was huge.
