I bought at two spot goby from the LFS last week and this guy isn't eating, at least from what I can see. The tank is very peaceful so I don't think it's stress related. I've tried flake food, pellet food, frozen cubes and even live brine shrimp the past two days and I don't see him eating anything. I know they do get a decent diet from scooping food from the sand, but I don't think my sand bed is really that dirty to sufficiently keep him healthy. I haven't spot fed before, and he'd likely run away if I did, but do you have any suggestions as to what I should do? I'd hate to lose $40 so quickly on a stubborn fish.
