20 gallon long Stocking Options

[maxthegladiator44]

I have a 20 gallon long tank running for 1 year. It currently has 2 clowns and a yw goby. I have a HOB filter, protein skimmer, and oversized UV light.
I would like to add some colorful and practical fish.
Here are a few possible additions I came up with, which one do you all think will work better:
1:
- royal gramma, 6L wrasse, hectors goby
2:
royal gramma, springers or yellowtail damsel, hectors goby
OR
3:
royal gramma, 2 damsels

Thank you all very much
