What to add

I recently got this 37gal display 10 gal sump and only have a mini clownfish. Any stock ideas are appreciated

Smaller tank - a Hector's Goby or Rainford Goby would be good for algae assistance.

Are you looking for specific colors? Springeri Damsels add a nice pop of blue to the tank and are good at eating some pests.

Clown Gobies come in a variety of colors.

Pistol Shrimp and prawn goby of some variety would be nice.

I'd do a possum or a pink streak wrasse once the tank gets a bit older, for now add a goby that you like (anything but a diamond watchman) and a pistol shrimp, maybe a pair for the clown? Then a tailspot blenny adds character and eats algae

Blennies and gobies are always a good choice. You could do a royal gramma as well. A smaller wrasse species is a good option.
