My Engineer Goby just love's brine shrimp. Shoot some into his home, and he'll eat it when no one's looking. It sounds like he's a little shy yet. Once he starts eating, on feeding days, he'll pop his head out to see if you brought something for him too. Don't overfeed though. Just shoot enough under the rock he lives in. He'll do just fine. Hope this helps! ....Angel :angel1:
