White cap goby & shrimp compatibility?

[ReeferHD]

Hey guys!
Was at the LFS today and saw they had a white cap goby, funny enough I was just looking at getting one of these last night, but I noticed they have it paired with a Randall’s pistol shrimp, i didn’t have enough time to observe them closely but I took some pictures. I read they only pair with one type of pistol (alpheus rubromaculatus)
So I’m wondering if anyone here has paired them with another type of shrimp, just wanna make sure they’ll get along in my tank,

Thanks

Put em on hold and picking them up later cause the price was too good, I’m reading that they’ll live together but won’t actually pair up, I guess I’ll be the guinea pig here to see if they are actually compatible lol, gonna keep yall updated.
