Brand new acan getting eaten

[ChiSox Rabbitfish]

Brand new acan in my tank opened up nicely but now my foxface keeps nipping at it he’s never nipped at any other coral in the tank not sure what to do I don’t have a spare tank to remove anything

You can try placing a basket/Tupperware with hole cut in it over it for now but once they start, its hard to break them of the habit
