Tang trouble

[SWFL Reefer]

Hi everyone, I have a powder blue Tang that is around 6 years old. He or she has started to nip at all of my Zoa's. Is this an indication that I need to provide more food as he/she grows? Do you think this fish will start to move on to other corals like LPS or SPS? I have 3 other tangs in the tank, will they learn this bad habit? Thank you.

Do you use Nori seaweed regularly in your tank? If not, you could try putting a sheet of this in the tank in order to maybe attract his attention from the zoas.

Feed the fish, probably trying to get algae. Fish that old should have at least a quarter nori a day.
