One of the tanks I maintain has a Banded Jawfish, boring colors but lots of character, he will watch for the food to hit the surface and then bolt out lightning fast to the top and back down. It's cool to watch. He'll eat when he gets hungry, I wouldn't worry too much about it.
My tanks: 120 Reef w/L2 Algae Scrubber, 60 Reef Pond w/floating Algae Scrubber, 40 Breeder Reef w/L2 UAS Tester Algae Scrubber
I maintain: 144 SW Reef w/L2 Algae Scrubber | 200 SW Reef w/L4 Algae Scrubber
