Need help picking out a goby for a 29 gallon

[AquaAlexCardinale]

I'm trying to come up with a goby I want to keep. First, I'll ask you which goby you would reccomend for a 29 gallon?
Here is the list I am thinking:
Pink Spotted Watchman goby
Candy Cane Goby
Yellow Watchman goby( usually come in very tiny in my area like the size of a elbow pasta or little bigger)
I'm looking for gobies that grow up to 4-5''
any ideas?

I love yellow watchman gobies. Some of the gobies with white body colors are harder to see in the tank.

How about a prawn goby paired with a pistol shrimp?

This is on my bucket list.
