Fish scared of veggie clip?

[tang_man_montreal]

Hey everyone,
I'm trying to feed Nori to my tangs... But they seem to be afraid of the veggie clip, or maybe don't like nori.
They havn't swam close to that area since I put it in.
Is this normal? And also, what size should I cut the nori that I place on the clip?
THanks!

i have the same situation but after a week or 2 they finally go over to it, in the begining i just a piece in 1" square approx for 4-5 hours and then take it out as soon as they figure it out u can put more in as they eat it
