I'm currently using the Two Little Fishes nori clips on each side of my tank but I find that it gets real messy with pieces of nori floating around the tank. I usually take a sheet and cut it in fours then fold those down and clip them in the morning and at night. My Melanarus Wrasse loves to pick at it and sometimes it seems like he just likes to tear pieces off for the fun of it. Has anyone used different alternative clips (netted, Nori nibbler, etc) that doesn't create as much waste and floating nori all over the tank?
