Who has a Yellow Watchman Goby?

[fkshiu]

I have a Diamond Watchman Goby which is pretty much the same thing as a Yellow Watchman. He is inseparable from the pistol shrimp and they make a great sand sifting team without displacing to much sand like a Sleeper Goby would. They've done such a great job that their little patch has been the only part of the sandbed that hasn't had any cyano issues. They live about a foot away from a pair of Sexy Shrimp and the goby has never shown as interest.
