Who's your daddy?!?
Just did a YouTube search on feeding Mandarin Gobies and came up with three pages of hits. They may help you get an idea of what has worked for other folks. There are several videos that reference feeding Rod's, pods, worms, and feeding with a turkey baster so maybe there's something there that you can learn from. It is encouraging that the fish is picking at your rocks. It may be that it has found at least enough of a critter population to sustain itself. Get to the store and get it some more.
