Feeding clip? I ahve had to stop using one. My tangs will pull the nori right out. so I have gone to splitting it up a bit smaller and hand feeding them. the SOhal and Naso are not shy about eating from my hand, and will let anyone hand feed them. the Purple is still a bit skittish but will steal from the others and they then come back for their replacement. the Naso will actually pull a good suction cup clip off the wall.
