The only possible exception is that there might be some sand sifting gobies that do need substrate. If anyone can confirm, that would be great.
In terms of a 14 gallon tank, you can opt for many choices such as:
Randall's Goby
Wheeler's Goby
Yellow Watchman Goby

There are some sand sifting gobies that won't work, like the sleeper - but that's not a nano fish at all, same goes for an engineer.
I'd also be careful with fish like the Randall's and things like the A. Hectori - they sometimes can be VERY particular eaters and end up wasting away like Dragonettes.
If you want a FEW fish, look at the Neon Gobies - those guys are great, they're community oriented and are great in a tank, very colorful and cute as heck.
