A dragon goby or banded sleeper goby

[Daylilly]

My goby is not eating any if the food I put in for the other. I just see him going for sand etc. I think he has became a bit skinny since I got him 3 weeks ago. Is he gonna starve? Will the stuff in the sand be enough for him to live?

What size is your tank and how long have you had it? What types of food have you offered? Sometimes garlic guard will help them want to eat. From what I have found on them they are wild caught which means they may not know what prepared food is.
