How to Encourage Goby in Quarentine to Eat?

[LeanneP]

I just got a Goby and pistol shrimp a couple of days ago and they are currently in a quarentine tank. The Goby is very shy and hasn't come out to eat at all. There are only two rocks in the tank so probably not a lot of food for him. I have tried feeding him brine shrimp soaked in garlic and some algea sheets. Any suggestions in encouraging him to eat?
