How long can nori be in the tank?

[BuddyBonButt]

How long should I leave my Nori in the tank? I have green Nori and one younger Foxface. Very occasionally I'll catch him nipping at it but he will never finish it. I feed half of a square folded up into a tiny Square and I put it on a clip. But he never finishes it. He's fairly new to the tank like just under a week. How long should I leave uneaten Nori in the tank? I am currently fighting diatoms.

I would use a smaller amount. I would just change it daily. My nori gets smelling funky after one day. All that remains is what is between the jaws of the clip. I turn it sideways so most of that is exposed and the fish love it.

I just leave it. Im not sure if that is right though. My baby yellow tang, and my blue tang are the only ones that nip at it. My cleaner shrimp likes some, and I just figure the CUC will appreciate it around.

I cut the sheet to 1.5x1.5 and just fold it in half.
