Found these super awesome Rainford Gobys while diving in Raja Ampat! Can't wait to get a pair for my tank!

IMO, they are an excellent addition to an established reef. Just check that they are eating whatever you plan on feeding them.
I just watched a documentary on that area! They were trying to tag pregnant manta rays so they can find out where they go to have their babies! Cool reef area!
They are fairly shy in the presence of some fish, and seem to be film-eaters, so mature tank! Beautiful vid!
Definitely second a mature reef, gobies are either the easiest fish to keep in our systems or very finicky with low survival; this one falls to the latter.
Mine rarely eats any food I put in the tank but is nicely plump. I frequently see him sand-sifting -- fun to watch. Probably helps that my sand was live -- collected from the Gulf by Tampa Bay Saltwater.
Yes, a well established tank is a must. I added one a few months ago and he and my 2 Conch's keep my sand immaculate. Since I've had him I haven't seen him eat any of the food I feed my fish, he sifts the sand all day long and when he's not sifting the sand he's picking at algae film around the tank.
Another good thing about them is they don't make a mess with the sand. Unlike some other sifters that rise into the water column when sifting he sifts close to the sand so none of it gets blown around and I have the very fine sugar type sand too. The worst is a light dusting here and there on some corals that eventually comes off with the current, I never had to dig out any corals.
