You talkin' about theb white sleeper head goby with the vivid yellow stripe? Notorius for perishing in tanks since they often don't take prepared foods. Good luck. Look at the bullet goby too. Not nearly as pretty, but they do move some sand too and eat better. Having said that, be wary of any of the goby's that like to pile sand up if you have corals placed on or very near the bottom. They tend to cover the corals with sand.
