Aquarium Albino Ancistrus Male and Fry munching Brussels Sprouts

My Ancistrus love Brussels Sprouts. I use frozen sprouts because they are already blanched. I punch a hole in the Brussels sprouts with a large finishing nail and thread a piece of bell wire through and hang it in the tank. The Ancistrus come running. They will eat this in two ir three days depending on what else i feed them. They smell pretty strong when the first start eating. My theory is that there is sulfur in the Brussels Sprouts that gets released when they chew on the sprouts.
