? Tiger Goby ?
 

I am looking at two needs for a new tank I am setting up, sand sifting & a watchmen for my Randalls.

I can use separate fish for this BUT I have been reading and looking around at a Tiger Goby:

I am wondering though.... They are commonly found online as Tiger Watchmen Goby but yet they are in the family with the sleeper gobys (Valenciennea).... Is it a Prawn Goby or a Sleeper (sand sifter) Goby ?? Or is it a Sand sifter that will live with a shrimp? So theoretically then he'll be out of the den more....

I used to have a Yellow Watchman and he earned the name watchman as he was always with the shrimp. Maybe these Tiger Gobys are not as co-dependant as a YWG ? They get out and sift but yet go 'home' with the shrimps ?

Anyone got any experience with these fish ?

That is the problem with common name. People can call a fish any names they like. But the fact that the particular fish in question is in the Valenciennea genus tells me that the fish won't live with a pistol shrimp. It just sifts sand.
