Hey all
I have a 20 gallon AIO with
2 clown fish
2 peppermint shrimp
3 turbo snails

I wanna add another fish but not sure what I can get away with/ won’t clash with my clowns

Any suggestions ?

Here’s a photo of tank for reference

A watchmen goby! They are super cool and a perching fish. A small blenny would be good too, those fish have fun personalities!
