Well there is a clear best way to feed nori without your fish ripping it to shreds and making a giant mess. The best part is, you don't need anything special. I have tried everything, built all kinds of contraptions, and my fish always rip it apart and down the overflow.
For no real reason I tried folding a sheet of nori like 6 times into a little dense rectangle and putting that on my seaweed clip. And my goodness it works. Don't believe me, just try it. There is no mess and it takes 3 yellow tangs, a sailfin tan, a blue tang, a moorish idol, and an angel fish quite a while to eat it all.
The seaweed on the clip in the picture is actually an entire sheet or nori folded up!
