Hey guys, I have the same type of goby as well and I have seen him nip polyps on many occations.. He is always fat, so I am sure he's chomping down more then I'd like to know about. I personally have whitnessed him eating food out of the water column, but not much. I have noticed several of my acro colonies showing a lot less polyp extension then usual during the day.. Night time they are normal.. I have seen him mostly bugging my pink a. milepora collony. My frist thoughts on this were to let nature run it's course and just have the corals recover on their own.. But now it appears he is doing more damage then I'd bargained for.. Hope I can catch 'em..
