I wind up adding more to the clip several times through out the day. My
question is; what am I doing wrong here?

I use a rubber band to hold nori on a polished oyster shell. I hung the
oyster shell about halfway up the tank with some fishing line and
another rubber band. It makes it harder for the Tang to just wolf down
or rip off a bunch of nori. Instead of 10 minutes, the Nori usually
lasts about 6 hours. I replenish whenever I see it empty which is about
twice a day.

I also learned to cut the nori into 4" by 1/2" strips. It seems to work
better. It only takes me a minute with a scissors.
