20g are that size that I find my favorite pico fish are hard to spot, but the larger fish are a bit too aggressive. If you really want clowns, get pink skunks as they are smaller and take longer to mature and spawn. I think they are usually less aggressive also.
Blennies stick with the tailspot, or similar sized guy.
Wrasses I would skip. The little guys are very secretive, but this is only from what I have heard. I have never kept the smaller ones.
Fun personality fish I have owned that would be good are clown gobies, masked gobies, neon gobies (a pair if you can find), shrimp and goby combination.
I like damsels in a small tank if you get the correct one. So far I have had good experience with talbots, azure and the Pavo one by Biota. These you can keep on in the tank with others just fine. Plus they have funny behaviors and good splash of color.
Links goby by Biota is secretive, but is a sand sifter and stays small. Court jesters are fun too.
For instance with masked gobies, you can get up to 3-5 in that tank without issue. They do not battle and it will have lots of space.
