Can you define "fine sand"
For the Goby, they'll be fine with anything 1.0-2.0mm (aragonite) or smaller. But you may go with something even smaller just incase you want a wrasse one day that wants to burry in it. I prefer the latter because it doesn't eliminate fish choices as my taste changes but others will prefer the largest possible to avoid a sandstorm.
I like Caribsea Aragamax Sugar-sized Sand .0.2-1.2.
