I go this little guy from SWSW last weekend. I also bought a pistol shrimp but it is in deep hiding - I haven't seen it at all. Anyway, this little guy is entertaining on its own.

Watchman Gobies come in several patterns and colors. That goby though is a Randall's Goby to be exact.
 
That's true. This guy's common name is orange striped prawn goby. I hope my pistol shrimp is still in my tank and that they find each other eventually.

From freshmarine.com

"The Randall's Goby is probably the most spectacular member of this genus. It is white with orange bands and a distinct spot on its first dorsal fin. This fish is well suited for aquarium life. It is not aggressive, except possibly towards conspecifics or towards other bottom-dwelling fishes, except for those that try to enter their preferred hiding place. More than one Randall's Goby can be kept in the same tank, as long as there is room for them to spread out on the bottom. Suitable hiding places should be provided to them and beware that the Randall's Goby may jump out of an open aquarium when startled. The Randall's Goby shares a burrow with one or more snapping. The mutualistic relationship between the Randall's Goby and alpheid shrimps that live together in the same burrow, has been known for many years.

The shrimp has poor eyesight. It builds and maintains the burrow while the Randall's Goby serves as a sentry at the burrow entrance. The shrimp spends much of the daylight hours "bulldozing" sand or rubble from the burrow. Each time it emerges from the burrow entrance, it rests one of its antennae on the body of the goby. If the Randall's Goby detects danger the posterior portion of its body quivers to alert the shrimp. The goby may also back into the burrow and block the shrimp's exit. If the threat escalates, the goby will dart straight into the burrow."
 
You know, I'm not sure. I have about 2" in my tank. I did have a jaw fish (may he rest in peace) who did quite well making multiple burrows. My biggest concern with this guy is that I might not have enough fine substrate - mine is more crushed coral. Also, he is not showing any sign of burrowing and I'm not sure if that is because my shrimp is nowhere to be seen or what that's about. The goby does eat like a little pig and seems otherwise fine.
