Yasha goby pair or single watchman goby?

My watchman goby just jumped out of my 120 yesterday, and after that I instantly went and bought some mesh to put over the tank. So as the problem is fixed I was wondering should I pull the trigger and try to pair some yasha gobies? Or stay with one watchman?

What other fish you have in it? 120 gal is rather larger, a tiny pair of shrimp goby may get rather lost in there, Consider Randal Goby. They are much more beautiful than Watchman Goby, and significantly larger than Yasha Goby

I’ve always been weird and liked the having micro fish in a big tank so that I can see a lot more natural behavior out of them. I will look into those though they are beautiful! Do they pair with pistol shrimp as well? I have a tiger in there that was paired with the ywg
