Will lower lip/jaw grow back?

[one clownfish]

My Clown Tang decided he wanted to take a piece of krill from my Crosshatch Triggers mouth and it didn't go so well. The lower lip is now missing and some jaw is exposed. Hes eating well and seems happy but he doesn't look good. Will it grow back?

over time yes.. might take 2 weeks or so but ya eventually it will.
