Stocking list for 20g fish tank

[clownfishluvr123]

I currently have a 20g fish tank. This is what I was planning to add in it:
2x ocellaris clownfish
1x Yellow watchman goby
1x royal gramma

Will this work? My tank is already cycled I just have to add fish.

Possibly but I'd reconsider the grama in a nano tank with 2 clowns that will be territorial.
