Shrimp goby/pistol shrimp with pair of jawfish?

[BlueSkyAT]

Hi all. I have a 120g with 60x18 footprint. I did some rock in the middle just to barrier the sandbed. Is it possible they might stay on "their" side, or will they just do whatever, and get along? yellow rose shrimpgoby and pair of yellowhead jawfish.

"Maybe" is all I could offer, although with a 120-gallon there's definitely enough real estate.
