I have no fish at this time.

Thanks for the guide on fish stocking.

My vote would be for possum wrasse and clown goby. Here are mine:

I’d add to the pink streak wrasse to your list to consider as well. All though, it seems possums are easier to find these days. 
 

I love yellow clown gobies, but there’s a couple things you should know about them before deciding on one. First, they’re one of the harder nano fish to get to eat frozen/flake/pellets. I’d ask the store to feed, to see if it’ll eat frozen before buying it. Secondly, if you plan on keeping SPS, there’s a good chance he’ll munch on the polyps of the SPS. They are adorable though! 
 

You could also do just about any of the shrimp gobies (yasha, high fin, yellow watchman, wheelers, etc.) and a candy cane pistol shrimp. 

Shark nose gobies are also great nano fish. 

 

If you want to get a blenny, a tail spot or two spot blenny would be the way to go. Both are herbivores, so they’d probably be best once your tank has matured some, and has algae for them to graze on.
