Yellowheaded jawfish eating????

[NeonSand]

I'm not sure my new jawfish is eating. He has been in the tank for about a week and has burrows all over the place. I'm not positive if he is chowing down because he doesn't come out to feed, or atleast I haven't seen him.

 

Should I be concerned? Is there something I could do to make sure he gets food?

 

thanks.
