I found the following method to be really easy and effective after having one of my nori clips break.
I had three 5"+ rabbitfish in my tank who could absolutely RUIN nori. For them, I found that it was fine to just throw in about 1/8 of a sheet every time I walked by the tank (not clip it, but literally toss it on top of the water).
They would play tug-of-war with the sheet and tear off small enough chunks for themselves in the process. For you, estimate what fraction of a sheet your fish could finish in one "sitting" and adjust accordingly. I think once the fish realize the nori will be delivered at the surface rather than on the clip, this feeding method works fine.
