It's also a possibility that that is a sign of the fish not being healthy and starting to break down which could mean disaster for your main tank if you moved him into there. 3 days is not long enough to determine if the fish is healthy or carrying any pathogens. I would make sure your water quality in the QT is right and add some PVC
piping pieces into the tank for the goby to hide in. Once you have all that, it should help the fish feel better and more secure.
The reason you QT fish is to make sure they are healthy enough to survive in your main tank. If the fish does poorly in QT, it will most likely also do poorly in your main tank. I would never risk my main tank for a fish doing poorly in the QT tank.
