There are several different types of watchman and sleeper gobies that do that. They are reef safe in the sense that they will not eat corals and such, but I would not recommend one if you are using a DSB for denitrification. They will deplete your tank of beneficial infauna like pods, thereby decreasing (if not destroying) the effectiveness of a DSB.
I had one (an orange diamond goby) and he depleted a thriving pod population in a 175 gallon within a few weeks.

a few weeks???!!! geeze man... thats why i dont get these type of things:yes: although im getting an antenna goby:yes: for me pistol

Awsome pistol! I've never had an antenna goby, but they are certainly cool looking fish. :yes:
And yeah... the tank was just full of pods and within a month, there were almost none to be seen. Made me so mad... hard lesson learned about researching fish before purchasing. Now I'm waiting for the pod population to recover so that I can get a mandarin.

haha yea they are sucking up your pods! If your going to have these fish I recommend a fuge to replentish your pods
I have a phyco Green Mandarin (Synchiropus splendidus from the dragonets spec.), and I agree, they are fun to watch!

A Jawfish will dig a hole in the aggregate and spit out the grains to clear the hole - constantly. I saw one at the Shedd Aquarium and had to have one. They are jumpers though....

An Engineer Goby will do this as well. If you go to MacsReef.com you'll see this being done. You just have to download the movie but it's pretty interesting!
